+# 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.
