More audio file type support in (openai-compatible) api?

Gemini API

i am trying to use audio in the openai compatible api:
however i get:
openai.BadRequestError: Error code: 400 - [{‘error’: {‘code’: 400, ‘message’: ‘Invalid audio format “m4a” for audio generation. Valid formats are: [wav, mp3]’, ‘status’: ‘INVALID_ARGUMENT’}}]

although this says more format are supported:

Supported audio formats

Gemini supports the following audio format MIME types:

  • WAV - audio/wav
  • MP3 - audio/mp3
  • AIFF - audio/aiff
  • AAC - audio/aac
  • OGG Vorbis - audio/ogg
  • FLAC - audio/flac

and this (Audio understanding (speech only)  |  Generative AI  |  Google Cloud) says even more format are supported:

Audio MIME type Gemini 2.0 Flash Gemini 2.0 Flash-Lite
AAC - audio/aac
FLAC - audio/flac
MP3 - audio/mp3
MPA - audio/m4a
MPEG - audio/mpeg
MPGA - audio/mpga
MP4 - audio/mp4
OPUS - audio/opus
PCM - audio/pcm
WAV - audio/wav
WEBM - audio/webm

sorry for the quick typing. time constrained. but thanks in advance!

what puzzled me and prompted me to try was that this (m4a) works at ai studio…

Hi,

The OpenAI comp runs against the Google AI Gemini API and there I do not see the m4a format as an accepted option either.

Cheers

is this an excuse for not accepting m4a? Aren’t we passing the base64 encoded version and a string for media_type?
