Audio Thing

Rust gRPC server plus Python workers for transcription and diarization.

ulti stage producer consumer pipeline with Postgres and gRPC

Components

• server/: Rust gRPC server that ingests audio and writes DB records.
• server/pyworkers/: Python workers for transcription (Whisper) and diarization (pyannote).
• proto/: gRPC definitions.
• migrations/: Postgres schema (goose).
• androidapp: Basic audio sampling grpc client.

Requirements

• Postgres running locally.
• Python env for server/pyworkers.
• GPU recommended for Whisper/pyannote.

Quick start

1. DB migrations:
   • make db-up
2. From server/:
   • make run

Notes

• DB env vars: POSTGRESS_USER, POSTGRESS_PASSWORD.
• Diarizer needs HF_TOKEN for the pyannote model.
