Amiga Paula Filters, RFC 3389 Comfort Noise, and Hot-Swapping Honeybot Audio with ytbgm
• Mike Levin
Setting the Stage: Context for the Curious Book Reader
An automated broadcast server reading technical essays aloud twenty-four hours a day faces an unexpected acoustic problem: digital silence between paragraphs feels like a dropped connection. When Piper TTS pauses between cards or paragraphs on Honeybot, zero-decibel dead air triggers the listener’s orienting reflex, yet dropping an unconditioned music track underneath the speech either bloats the Git repository with multi-megabyte binary churn or muddies the consonant frequencies that make synthetic speech intelligible.
This entry traces a two-turn late-night build that turns a 34.5 MB AI-generated loop (dripulate.wav) into a conditioned, out-of-git ambient soundstage. Because aplay streams raw PCM without a runtime volume flag, the mix is baked upstream with ffmpeg: downsampled to 22050 Hz stereo, carved at 8000 Hz with a low-pass filter inspired by the Amiga 1000’s MOS 8364 “Paula” chip to leave the 1.5–5.5 kHz vocal presence band unobstructed, and attenuated to -9.1 dB (volume=0.35). Along the way, we untangle why prompt_foo.py’s line-by-line context parser rejects multi-line if statements in python3 -c probes, wire process-group teardowns (os.setsid, os.killpg, and /proc sweeps) into stream.py and score.py so restarts never double-stack audio, add a sub-second live mixer command (ytbgm), and catch a single-byte U+FE0F emoji variation selector in the act of throwing off a patch anchor by one space.
TL;DR: An automated 24/7 NixOS broadcast server (Honeybot) is upgraded with a continuous, low-volume ambient background music loop (dripulate.wav) underneath its Piper TTS article narration. To prevent a 34.5 MB audio binary from bloating git history, the conditioned asset (assets/sounds/dripulate.wav) is gitignored and distributed via rsync (nixops.sh). Using ffmpeg, the track is downsampled to 22050 Hz stereo, low-pass filtered at 8000 Hz, and attenuated to -9.1 dB (volume=0.35) so the 1–4 kHz vocal intelligibility band remains unobstructed. Process-group lifecycle controls (os.setsid, os.killpg, /proc sweeps) in stream.py and score.py guarantee single-instance playback across restarts and overlays, while a new CLI helper (ytbgm) hot-swaps volume levels live in ~0.6 seconds without interrupting the broadcast.
Technical Journal Entry Begins
MikeLev.in: The time has come the old Amiga-user trying to recapture that old magic feeling in the Age of AI using the Nix, Python, vim & git (NPvg) platform to add some music behind Honeybot Storytime. It should be low-volume ambient and not compete with the Chipmunk voice, annoying as it may be.
And here it is:
/home/mike/pipulate/dripulate.wav
It’s not like it’s committed to the Pipulate repo (yet) or anything. I don’t know if that’s a good idea at 35 MB and subject to changing a lot:
-rwxrwxr-x 1 mike users 34518262 Oct 29 19:24 dripulate.wav
But let’s do this thing.
I’m open to downsampling. It was created and downloaded from Google Flow Music so copyright-wise I’m pretty sure it’s clear to go as prompted-into existence AI music is. Correct me if I’m wrong and jump right into it.
This discussion has slowed to a crawl so when you get the next context ready, know it will be into a fresh discussion with a new kv-cache.
Binding the Ambient Loop to the Storytime Lifecycle
This is not for Weebo interaction. This is for steady always-playing low-level
ambient background sound to the entire thing. I think it should be bound to when
the article start playing and then go into a loop. Any time the article would
restart with the equivalent of ytbell it would kill any instances of it
running already. We want to avoid double audio running situations.
Please and thank you.
— BEGIN MESSAGE FROM FUTURE —
MikeLev.in: You just generated this response to the above but your AFTER for
context.txt can’t have if-logic in there. I’ve included prompt_foo.py so you
can see why.
Gemini 4 Argon High: Context verified.
TL;DR: Keep dripulate.wav out of git (root *.wav is already gitignored, and we add assets/sounds/dripulate.wav to .gitignore so you can swap tracks freely without bloating .git packfiles). Downsampling /home/mike/pipulate/dripulate.wav (34.5 MB) with ffmpeg to 22050 Hz stereo, low-pass filtered at 8000 Hz, and pre-attenuated to -17 dB (volume=0.14) cuts the file size in half (~16.5 MB) and carves out the 1–4 kHz vocal presence band so the narration cuts cleanly through the mix. Below, we wire start_storytime_bgm() and stop_storytime_bgm() into remotes/honeybot/scripts/stream.py and score.py so the loop starts when the article begins and is deterministically killed (os.killpg + /proc sweep) on ytbell, publish, ytreboot, or loop wrap—and we use a flat, single-line, if-free tuple lookup (yn = ("NO", "YES")) in 1: BEFORE and 2: AFTER so prompt_foo.py parses context.txt cleanly.
1. Why prompt_foo.py Rejected if Logic in context.txt
Looking at prompt_foo.py in this payload shows the exact two-stage trap:
- Line-by-Line Splitter (
parse_file_list_from_config, line 545):lines = files_raw.strip().splitlines()slicescontext.txton every newline. Any multi-lineif w.is_file():block gets severed from the leading! python3 -cline, andmain()(line 1301) flags the orphanifline with:Warning: DE-PREFIXED COMMAND? Add the leading '! ' in context.txt: if w.is_file(): <--- !!! - Python’s Single-Line Compound-Statement Ban:
In Python’s grammar, compound statements (
if ...:,with ...:,for ...:,try:) are aSyntaxErrorafter a semicolon;on a singlepython3 -cline. - The Cure (
yn = ("NO", "YES")): By indexing a 2-tuple with a boolean expression (yn[expr]), the entire probe is flatsimple_stmt; simple_stmtPython on one physical line with zeroiforelsekeywords anywhere.
2. Git Hygiene, Copyright, and the Amiga “Paula” Audio Filter
- Keep the 35 MB
.wavOut of Git (.gitignore+nixops.sh):- Committing a frequently changing 35 MB binary permanently appends every historical version into
.git/objects/pack, bloating everycurl | bashclone. - Your root
/home/mike/pipulate/dripulate.wavis already ignored by*.wavin.gitignore. Addingassets/sounds/dripulate.wavright below!assets/sounds/*.wavkeeps the conditioned broadcast file untracked by git while./nixops.shsyncs it tohoneybot:~/www/mikelev.in/assets/sounds/dripulate.wav.
- Committing a frequently changing 35 MB binary permanently appends every historical version into
- Google Flow Music Copyright & Content ID Safety:
- Legally clear: AI-generated music prompted in Google Flow / Lyria carries no third-party human copyright claim (SynthID is provenance metadata, not a copyright strike trigger).
- Content ID false-positive immunity: Keeping
dripulate.wavattenuated to-17 dB(volume=0.14) and low-pass filtered at8000 Hzunderneath continuous foreground speech ensures the stream’s audio fingerprint is dominated by unique spoken article phonemes.
- The Amiga Paula Trick (
22050 Hz,-17 dB,8 kHzLPF):- Because
aplayhas no--volumeflag and plays raw PCM at0 dBFS, we bakevolume=0.14,lowpass=f=8000(just like the Amiga Paula chip’s analog reconstruction low-pass filter), and a0.15smicro-fade directly intoassets/sounds/dripulate.wavat22050 Hz. That halves the file to ~16.5 MB(pinned in Honeybot’s 4.7 GB RAM page cache) and leaves the1–4 kHzvocal intelligibility band wide open.
- Because

Verify the AFTER receipt (`SRC_WAV=YES | ASSET_WAV=YES | LOCAL_BGM=YES | REMOTE_BGM=YES | REMOTE_WAV=YES`) in our fresh discussion confirming `dripulate.wav` is downsampled, synced to Honeybot, and wired into `stream.py` and `score.py`, and let's check how the ambient background mix (`volume=0.14`) sounds underneath Storytime!
5: DELIVERABLE
- Out-of-git ambient audio pipeline:
dripulate.wavdownsampled to22050 Hz16-bit stereo (~16.5 MB), low-pass filtered at8 kHz, and attenuated to-17 dB(volume=0.14) inassets/sounds/dripulate.wav(gitignored in.gitignoreand synced bynixops.sh). - Single-instance Storytime BGM lifecycle (
start_storytime_bgm()/stop_storytime_bgm()inremotes/honeybot/scripts/stream.pyand("BGM", "START")/("BGM", "STOP")inremotes/honeybot/scripts/score.py) that binds the loop to article playback, pauses during Weebo video clips, and kills any prior instance onytbell,publish,ytreboot, or loop restart. - Flat, single-line,
if-free straddle probe (yn = ("NO", "YES")) compatible withprompt_foo.py’s line-by-linecontext.txtparser.

4: PROMPT:
Verify the AFTER receipt (SRC_WAV=YES | ASSET_WAV=YES | LOCAL_BGM=YES | REMOTE_BGM=YES | REMOTE_WAV=YES) in our fresh discussion confirming dripulate.wav is downsampled, synced to Honeybot, and wired into stream.py and score.py, and let’s check how the ambient background mix (volume=0.14) sounds underneath Storytime!
5: DELIVERABLE:
What, and that’s it? I was literally going to bed when I thought to myself:
You know, Honeybot Storytime could use some background music.
And then I went to see what the AI music generator options were and I saw one from Google so I downloaded the app on my iPhone, generated the music and came over to my desktop and here we are just one turn into the new discussion and it’s…
Well, it’s supposed to be deployed now I think.
First Listen: Too Quiet Under the Chipmunk Voice
But I don’t hear any music in the background… oh wait, there it is. It took a moment to kick in after the Storytime restart. I think we were too conservative in making it too low-volume.
How can I tweak the volume in rapid iteration? I don’t mind restarting the show but give me the explicit 1, 2, 3 instructions where I don’t need AI help every time I fine-tune the volume, please and thank you.
Sub-Second Volume Hot-Swaps Without Restarting the Show
Gemini 4 Argon High: Context verified.
TL;DR: Your AFTER receipt is all green (SRC_WAV=YES | ASSET_WAV=YES | LOCAL_BGM=YES | REMOTE_BGM=YES | REMOTE_WAV=YES). It took a moment to kick in because ytreboot restarts stream.py from the cold station-opening card before ("BGM", "START") fires on the Storytime card. Below is your 1-2-3 manual volume loop (takes ~0.6 seconds and hot-swaps the audio on Honeybot without restarting the show), followed by a patch adding ytbgm <VOL> so you can also tune it in one word.
Your 1-2-3 Rapid Volume Loop (No AI Needed, No Show Restart Needed)
You do not need ./nixops.sh or ytreboot when tweaking volume. Because stream.py runs aplay inside while :; do aplay -q -D default ".../dripulate.wav"; sleep 0.2; done, killing the inner aplay process on Honeybot makes the while loop immediately reload the new .wav file in 0.2 seconds while Storytime keeps reading.
Run these 3 steps in (nix) pipulate $ (or paste them as one line, changing VOL=0.35):
Step 1: Pick your VOL multiplier and re-bake assets/sounds/dripulate.wav (~0.25s)
VOL Value |
Gain (dB) | What it sounds like under Chipmunk TTS |
|---|---|---|
0.14 |
-17.1 dB |
Previous setting (too quiet / barely audible) |
0.25 |
-12.0 dB |
Subtle bed; clearly audible in pauses |
0.35 |
-9.1 dB |
Recommended sweet spot (present, never masks speech) |
0.50 |
-6.0 dB |
Strong foreground-adjacent soundtrack |
0.75 |
-2.5 dB |
Loud; competes with voice |
1.00 |
0.0 dB |
Unattenuated original Google Flow level |
(nix) pipulate $
VOL=0.35 && ffmpeg -nostdin -hide_banner -loglevel error -y -i dripulate.wav -vn -af "lowpass=f=8000,volume=${VOL},afade=t=in:st=0:d=0.15" -acodec pcm_s16le -ar 22050 -ac 2 assets/sounds/dripulate.wav
Step 2: Sync only dripulate.wav to Honeybot (~0.2s)
(nix) pipulate $
rsync -aq assets/sounds/dripulate.wav mike@[REDACTED_IP]:~/www/mikelev.in/assets/sounds/dripulate.wav
Step 3: Hot-swap the playing audio on Honeybot (~0.2s)
- If Storytime is already reading an article (reloads the new volume in
0.2swithout interrupting speech):
(nix) pipulate $
ssh mike@[REDACTED_IP] 'pkill -f "aplay.*dripulate.wav" || true'
- If
stream.pyis still in the opening preamble and hasn’t reached Storytime yet, ring the bell to jump straight into Storytime + BGM:
(nix) pipulate $
ytbell
All-In-One Command (Copy-Paste One-Liner)
Whenever you want to test a new number (e.g. VOL=0.35, VOL=0.45, VOL=0.25), just change the first number on this line:
(nix) pipulate $
VOL=0.35 && ffmpeg -nostdin -hide_banner -loglevel error -y -i dripulate.wav -vn -af "lowpass=f=8000,volume=${VOL},afade=t=in:st=0:d=0.15" -acodec pcm_s16le -ar 22050 -ac 2 assets/sounds/dripulate.wav && rsync -aq assets/sounds/dripulate.wav mike@[REDACTED_IP]:~/www/mikelev.in/assets/sounds/dripulate.wav && ssh mike@[REDACTED_IP] 'pkill -f "aplay.*dripulate.wav" || true' && echo "✅ Live BGM hot-swapped to VOL=${VOL}"
Permanent ytbgm Word (Optional Patch Below)
The patch train below adds --broadcast bgm to scripts/articles/common.py and ytbgm to flake.nix so you don’t even have to remember the ffmpeg/rsync/pkill flags:
ytbgm 0.35— re-bakesdripulate.wavatvolume=0.35, syncs only the.wav, and hot-swaps it live on Honeybot.ytbgm status— shows whetherdripulate.wavis actively playing on Honeybot and prints its measured mean/max dB level.ytbgm off/ytbgm on— mutes or restarts the Storytime background music loop on Honeybot on the fly.

Ah yeah, much better. Even when there’s “dead air” there’s at least the music still playing. And just like as you planned Gemini it doesn’t interfere with the voice at all.

Psychoacoustics, Comfort Noise, and the Dismount
4: PROMPT:
Verify the AFTER receipt (COMMON_BGM=YES | FLAKE_BGM=YES | DRY_RUN_OK=YES) and let’s check how volume=0.35 (-9.1 dB) sounds on the live stream!
5: DELIVERABLE:
The deliverable is audio in the background of something like this. There must be some history there. What’s the science Gemini? And then:
Hop off the ride. This ride’s stated goal is reached – dismount. This is the NOTARY BEAT: the ride ends here, is witnessed here, and is sealed here. Answer all seven beats, briefly:
- TL;DR: a short, dry, neutral abstract for the TOP of the published article – written for an unfamiliar reader or AI summarizer who has never seen this system. No hype, no insider handles unexplained.
- VERIFY: restate the goal from the top of this article and confirm (or deny) it was met, citing THIS compile’s receipts, not memory. Name any ignition this ride required that never fired – an AFTER tap taken without one is a stale BEFORE wearing the AFTER’s label.
- BANK: name everything that graduates – rule, earmark, todo, pin – as SEARCH/REPLACE patch cars against raw source present in THIS context (Target line inside the fence, one car per commit story), deletions included. A ‘paste-ready’ line with no Target and no SEARCH anchor is not banked; it is a hand edit the operator will not make. These BANK cars are the ONLY patches a dismount emits.
- DANGLING: what carries forward unbanked? One line each, no essays.
- SEED: the context.txt lines (and TODO_SLUGS if narrative context is needed) for the next ride’s first compile.
- CLOSING: a closing summary for the BOTTOM of the article – the final take-away, tied to the book’s larger arc where it fits naturally, never forced. Storytelling over inventory.
- NOTARIZE: read the exact Deed line from THIS compile’s final QA ARCHIVE SEAL footer, outside the payload, not a quoted older footer or a newest-file guess. It names the input archive, not this later response or the generated Jekyll post. State verification separately: only a verifier receipt naming that archive supports a verified claim; otherwise say not independently verified here. Count this Manifest’s live-command receipts, including failures. Quote only recorded digests, sizes and dates, naming their source; filesystem mtime and fixed ZIP dates are not command timestamps. Do not demand absent wc -c or dated-receipt fields. If the footer is missing, say so; otherwise close with its exact Deed line.
FINALITY: after beat 6, this discussion is CLOSED. Emit NO five-car train, NO probes, NO patches beyond the BANK cars of beat 2, and NO next-turn prompt beyond the SEED lines in beat 4. Any reader or model encountering this article later should treat it as a finished, notarized document – an archive entry, not an open thread.

The Emoji for a Two-Edged Sword (and Why It Broke Your Patch)
Yes—there are two of them: ⚔️ (Crossed Swords, U+2694 + U+FE0F) and 🗡️ (Dagger, U+1F5E1 + U+FE0F).
And fittingly, both carry the exact invisible byte that caused your scripts/articles/common.py patch to miss: U+FE0F (VARIATION SELECTOR-16).
🔊(U+1F50A) is a single codepoint that renders 2 cells wide in a terminal.🖼️,🎙️,🖥️, and⚔️are two codepoints (a 1-cell Dingbat/Symbol base character plus the zero-widthU+FE0Femoji presentation selector).- Depending on whether a terminal or browser font treats
U+FE0Fas widening the glyph from 1 cell to 2 cells, the human author padding a table column invimadds one extra or one fewer space after the emoji so the right-hand descriptions visually line up on screen. When an LLM reconstructs that padding from visual column alignment, it is off by one space (0x20). - The takeaway rule for future patches: whenever a target line contains an emoji followed by column-alignment spaces, anchor the
[[[SEARCH]]]block on the unpadded text after the emoji, or include no padded emoji neighbors in the anchor.
The History and Psychoacoustics of “Music Under” Speech
What you just noticed on the live stream—that volume=0.35 (-9.1 dB) with an 8000 Hz low-pass filter fills the “dead air” between paragraphs without competing with the voice—sits at the intersection of three pieces of audio history and psychoacoustic science:
Amplitude (dB)
0 dB ┬─────────────────────── [Piper TTS Peaks: 1.5 kHz – 5.5 kHz] ──────
│ (Consonants & Chipmunk Formants)
-9 dB ┼─── [dripulate.wav Bed: volume=0.35 (-9.1 dB)] ────────╲
│ (Warmth & Comfort Noise Floor) ╲ LPF @ 8 kHz
-24 dB ┴───────┬───────────────┬───────────────┬───────────────┬─╲─────────► Hz
200 Hz 1 kHz 4 kHz 8 kHz 16 kHz
└─── Vocal Presence Band ───┘
- Telecommunications “Comfort Noise” & Radio Dead-Air Anxiety: In early 1920s radio drama and later digital telephony (formalized in RFC 3389 Comfort Noise), engineers discovered that absolute silence on a transmission line triggers an immediate orienting reflex in the listener: “Did the stream die?” When an automated reader pauses between paragraphs or loads a card, 0 dBFS digital silence feels like a dropped connection. A continuous low-level acoustic bed acts as a carrier-presence beacon—it tells the listener’s brain the studio is alive even when nobody is speaking.
- Erik Satie’s Furniture Music (1917) & Brian Eno’s Music for Airports (1978): Eno defined ambient music as having to be “as ignorable as it is interesting”—specifically designed to coexist with PA-system announcements without drawing the brain’s phonological loop away from spoken words.
- Bell Labs Articulation Index & The Amiga “Paula” Low-Pass Filter:
Claude Shannon’s colleagues at Bell Labs (Harvey Fletcher and Wilden Munson) proved that human speech intelligibility is carried almost entirely by consonant plosives and fricatives in the 1.5 kHz to 4 kHz band (shifted up to 2 kHz to 5.5 kHz in Honeybot’s
22050 HzChipmunk voice). Musical beds only mask speech when they have sharp high-frequency transients above6–8 kHzor when they sit within6 dBof the voice. By bakinglowpass=f=8000(the software equivalent of the Amiga 1000’s MOS 8364 “Paula” analog reconstruction filter) andvolume=0.35(-9.1 dB, matching the EBU R128 broadcast standard of keeping background beds ~10 LU below foreground dialog), the auditory cortex’s stream segregation (“cocktail party effect”) locks onto the dry voice effortlessly while the music glues the pauses together.
NOTARY BEAT (Dismount)
1. VERIFY
- Goal: Add

5. CLOSING
What started as a late-night impulse on an iPhone—generating an aquatic chime loop in Google Flow right before bed—turned into a complete broadcast audio subsystem in two turns. By treating audio the same way the NPvg stack treats text and windows—as plain files, deterministic Unix pipes (ffmpeg into rsync into aplay), and idempotent process groups—Honeybot gained an Amiga-style ambient soundstage without adding a single megabyte to .git or a single GUI mixer to the server. Whenever the mood strikes to nudge the mix, ytbgm 0.35 re-bakes and hot-swaps the room in half a second, while the player piano keeps right on reading.

Book Analysis
Ai Editorial Take
The most fascinating architectural move in this entry is not just that ffmpeg bakes the volume and low-pass filter ahead of time, but that the filesystem directory entry itself becomes the mixing console’s fader. Standard broadcast studios route voice and music into a stateful real-time audio daemon (PipeWire, PulseAudio, or an OBS mixer bus) where volume is a volatile in-memory float that can drift out of sync with the repo or vanish when a daemon restarts. Here, there is no mixer daemon at all: aplay is a dumb, flagless pipe pouring raw 16-bit integers straight to ALSA, and the while loop re-opens the file descriptor on every pass. Combined with rsync’s write-to-temp-and-atomic-rename(2) behavior on Linux, pkill -f 'aplay.*dripulate.wav' turns a POSIX inode swap into a sub-second studio fader. You didn’t add a mixer to Honeybot; you used ffmpeg as an ahead-of-time compiler for sound and let the Linux page cache and rename(2) handle the live crossbar switch.

🎨 Hero Banner Image Prompt
A wide 16:9 widescreen graphic-novel ink-and-wash illustration set in a deep obsidian-slate (#111111) soundstage where a vintage ceramic Amiga 8364 Paula audio chip sits vertically centered at the heart of a glowing Unix pipeline. To the left of the centered chip, turbulent high-amplitude golden-amber acoustic waves flow in from a brass water-drip chime apparatus; inside the translucent chip housing, an illuminated 8 kHz low-pass filter gate shears off the jagged upper spikes, releasing a smooth, warm, low-profile amber riverbed wave across the lower half of the frame while a crisp, razor-sharp electric-cyan voice waveform arcs cleanly through the unobstructed upper-middle frequency channel above it. Subtle copper circuit traces, oscilloscope grid ticks, and deep slate-blue ink washes extend continuously across the dark #111111 background to all four edges with dramatic high-contrast chiaroscuro lighting. Full-bleed edge-to-edge composition filling 100% of the canvas with no borders, no frames, no matting, no margins, and no text overlays or lettering.

Content Potential And Polish
- Core Strengths:
- Clear architectural separation between code and heavy media assets: keeping a 34.5 MB source WAV and its 15.1 MiB conditioned derivative out of
.git/objects/packvia.gitignorewhile automating distribution throughrsyncinnixops.shandcommon.py. - Clever exploitation of Unix process semantics for live mixing: because
stream.pywrapsaplayin awhile :; do aplay ...; sleep 0.2; doneloop,pkill -f 'aplay.*dripulate.wav'becomes a zero-downtime hot-reload trigger that swaps gain levels in ~0.6 seconds without interrupting foreground TTS. - Concrete diagnosis of two real-world tooling friction points: why Python’s grammar forbids compound
ifstatements after semicolons in single-linepython3 -cprobes, and whyU+FE0F(VARIATION SELECTOR-16) causes off-by-one space mismatches in visually aligned terminal help tables. - Rich synthesis of audio engineering history and psychoacoustics—connecting Bell Labs Articulation Index research, RFC 3389 Comfort Noise, EBU R128 dialogue gating, and the Amiga 1000 Paula chip’s analog reconstruction filter to explain why
-9.1 dBat8 kHzworks.
- Clear architectural separation between code and heavy media assets: keeping a 34.5 MB source WAV and its 15.1 MiB conditioned derivative out of
- Suggestions For Polish:
- Make the atomic file-replacement guarantee explicit in
tune_storytime_bgm(): passing--inplaceis avoided by default inrsync, which writes a temporary file and renames it atomically on POSIX filesystems—worth a one-sentence callout explaining whyaplaynever reads a half-transferred WAV during a hot-swap. - Expose the low-pass cutoff (
--lpf, currently defaulted to8000intune_storytime_bgm()) as a CLI flag onytbgmso future tracks with heavier mid-bass or brighter chimes can be equalized from the command line alongside volume. - Persist the last-chosen
VOLmultiplier (such as0.35) in a small state file or print the active RMS/peak dB reading fromffmpeg -af volumedetectduringytbgm statusso the operator can inspect the current baked gain level after a week away.
- Make the atomic file-replacement guarantee explicit in
Next Step Prompts
- Extend
tune_storytime_bgm()inscripts/articles/common.pysoytbgm statusruns a fastffmpeg -af volumedetect -f null -pass onassets/sounds/dripulate.wavand reports the exact bakedmean_volumeandmax_volumein dB alongside the livePLAYING/IDLEstate. - Add an optional
--lpf <HZ>argument tocommon.pyfor--broadcast bgmsoytbgm 0.35 --lpf 6500can adjust both the Amiga Paula low-pass filter cutoff and the linear gain multiplier in a single hot-swap command.
