millet-record 0.4.4

Lightweight capture-only subset of millet (formerly meetscribe-record): record dual-channel meeting audio (mic + system) with no transcription/diarization/summarization deps. Named after the Ottoman millet system. Part of the vezir ecosystem.

millet-record

Lightweight capture-only subset of millet (formerly meetscribe-record).

Records dual-channel meeting audio — your microphone on the left channel, system/remote audio on the right — into a single stereo WAV via PipeWire or PulseAudio + ffmpeg. Ships none of millet's transcription, diarization, summarization, or PDF dependencies; install footprint is ~30 MB instead of ~3 GB.

Full release history in CHANGELOG.md. Named after the Ottoman millet system. Part of the vezir ecosystem.

When to use which

Need	Install
Just record audio (e.g., for vezir thin clients, or local archival)	pip install millet-record
Record + transcribe + diarize + summarize + PDF	pip install millet-pipeline (depends on millet-record)

Install

pip install millet-record

System deps (apt example):

sudo apt install ffmpeg pulseaudio-utils

CLI

millet check                   # verify prerequisites
millet devices                 # list audio sources
millet record                  # record dual-channel WAV; Ctrl+C to stop
millet archive                 # compress past WAV recordings to OGG/Opus
millet request-permissions     # macOS Sequoia 15+: trigger Microphone /
                               # System Audio Recording TCC prompts
                               # (Apple removed the manual '+' button in
                               # System Settings, so apps must request)

millet record writes to ~/millet-recordings/meeting-YYYYMMDD-HHMMSS/...wav unless -o is passed. See millet record --help for options.

When millet-pipeline is also installed, additional subcommands (transcribe, run, label, sync, gui, ...) become available under the same millet command via Click entry-points.

Legacy meet command

The pre-rename meet console script keeps working for two minor versions (until millet-record 0.6.0). It prints a deprecation warning on each invocation and forwards to the millet group. Set MILLET_SUPPRESS_DEPRECATION=1 to silence the warning during transition.

Architecture

millet-record exposes a stable package millet_record containing:

• millet_record.capture — ffmpeg-backed dual-channel capture (RecordingSession, watchdog, drain buffer)
• millet_record.audio — stereo channel reading + ffmpeg-based audio compression
• millet_record.utils — formatting helpers (HH:MM:SS, file sizes)
• millet_record.languages — language constants used by capture flow
• millet_record.cli — millet console-script entry point

The legacy meet_record package name is still importable via a sys.modules alias + a meta-path finder, so existing from meet_record.X import … keeps working unchanged. Removed in millet-record 0.6.0.

millet-pipeline depends on this package and re-uses these modules, plus its own heavy modules (transcribe, label, voiceprint, summarize, sync, pdf, gui).

macOS (Apple Silicon)

pip install millet-record on macOS 14.4+ Apple Silicon ships a bundled meet-record-mac Swift sidecar that captures via Core Audio Process Tap + AVAudioEngine — no PulseAudio, no BlackHole, no extra install. millet record uses it by default.

Note: the Swift binary itself is still named meet-record-mac for now — renaming would require macOS code-signing bundle-path changes that aren't worth doing as part of the package rename. Tracked as a follow-up; doesn't affect end users.

First run prompts for Microphone and System Audio Recording permissions via the standard macOS TCC dialogs; both are required for full dual- channel capture (mic on left, system on right). See mac/README.md for the sidecar's CLI surface, level analysis recipes, and environment variables.

On macOS Sequoia 15+, Apple removed the manual + button from System Settings → Privacy → Microphone, so users can no longer add permissions before running the app. The millet request-permissions subcommand explicitly calls AVCaptureDevice.requestAccess(for: .audio) to trigger the TCC dialog. millet check will tell you which permission is missing and suggest running request-permissions.

Set MEET_RECORD_MAC=0 to force the legacy ffmpeg+PulseAudio path (diagnostic kill switch only — that path will fail on a stock macOS install because there is no PulseAudio device). Intel Macs and macOS < 14.4 are unsupported.
