## Recording Workflow
|
||||
|
||||
The MVP does not include its own audio recorder.
|
||||
|
||||
OBS Studio is the recommended reference recorder for online meetings. It can
|
||||
|
||||
capture system audio and microphone audio without joining the meeting as a bot.

||||

||||

# ADR 0009: Use External Audio Recording for the MVP
|
||||
|
||||
## Status
|
||||
|
||||
Accepted
|
||||
|
||||
## Context
|
||||
|
||||
Reliable simultaneous capture of system audio and microphone audio is highly
|
||||
platform-specific.
|
||||
|
||||
OBS Studio already provides stable, configurable and cross-platform audio
|
||||
capture. Reimplementing audio capture during the initial project phase would
|
||||
add substantial complexity without directly improving transcription quality.
|
||||
|
||||
The primary value of the Meeting Assistant lies in transcription, speaker
|
||||
diarization, analysis, structured knowledge extraction and export.
|
||||
|
||||
## Decision
|
||||
|
||||
The MVP shall not require an integrated audio recorder.
|
||||
|
||||
OBS Studio is the recommended reference recorder for online meetings.
|
||||
|
||||
The Meeting Assistant shall initially import existing audio recordings.
|
||||
|
||||
Initially supported input formats shall include:
|
||||
|
||||
- WAV as the preferred processing input
|
||||
- FLAC as a lossless import and archive format
|
||||
|
||||
Support for additional formats such as MP3, M4A and Opus may be added later.
|
||||
|
||||
The existing `recorder` module shall remain in the project architecture so that
|
||||
integrated recording can be implemented in a later phase without restructuring
|
||||
the application.
|
||||
|
||||
## Consequences
|
||||
|
||||
- Development can focus on transcription and downstream processing.
|
||||
- Platform-specific audio capture complexity is deferred.
|
||||
- OBS configuration remains outside the Meeting Assistant.
|
||||
- Users must start and stop the initial recording separately.
|
||||
- Imported recordings require validation before processing.
|
||||
- A future integrated recorder remains possible.

# Module Responsibilities
|
||||
|
||||
## Input and Ingest
|
||||
|
||||
Responsible for importing existing recordings into the application.
|
||||
|
||||
Initial reference source:
|
||||
|
||||
- OBS Studio
|
||||
|
||||
Initial supported formats:
|
||||
|
||||
- WAV
|
||||
|
||||
- FLAC
|
||||
|
||||
Responsibilities:
|
||||
|
||||
- validate the input file
|
||||
|
||||
- collect technical metadata
|
||||
|
||||
- calculate checksums
|
||||
|
||||
- copy or move the recording into the meeting directory
|
||||
|
||||
- create the initial Recording domain object
|
||||
|
||||
The ingest component must not perform transcription or modify the audio content.
|
||||
|
||||
## Recorder
|
||||
|
||||
Responsible only for capturing audio.
|
||||
The recorder module is reserved for a future integrated recording implementation.
|

||||
Input:

Studio as the recommended reference recorder.

## Initial Recording Strategy
|
||||
|
||||
The MVP does not implement platform-specific audio capture.
|
||||
|
||||
OBS Studio is the recommended reference recorder for online meetings.
|
||||
|
||||
The application initially processes existing WAV or FLAC recordings. Integrated
|
||||
|
||||
recording remains a future extension and must not be required by transcription,
|
||||
|
||||
diarization or analysis modules.

# Storage Strategy
|
||||
|
||||
The domain model is independent of the storage backend.
