Problem Description

When using https://borgcloud.org/api/v1 (from https://borgcloud.org/speech-to-text) I get

Exception: External: 400 Client Error: Bad Request for url: https://borgcloud.org/api/v1/audio/transcriptions
Unsupported MIME type: 'audio/wav'. Supported types are: audio/mpeg (.mp3), audio/mp4 (.m4a with AAC codec), audio/ogg (.opus).

Desired Solution you'd like

An option to encode audio for the OpenAI-compatible STT endpoint. Preferably Opus.

Are you tried to set Audio Supported MIME Types just for those types, e.g audio/mpeg, audio/mp4; codecs=ACC, audio/ogg; codecs=opus
