# Audio file input

Audio file input covers recorded uploads and is separate from realtime voice. Transcription, timestamps, speaker labels, and acoustic analysis are recorded as qualifiers only when documented.

## Current support at a glance

Audio file input: 5 supported, 0 partial, 0 unsupported, 26 unreviewed across 31 cataloged products.

- Reviewed current products: 5 of 31
- Supported: 5
- Partial: 0
- Unsupported: 0
- Unreviewed: 26
- Not applicable: 0

Unknown or unreviewed means insufficient published evidence; it does not mean unsupported.

This row covers recorded audio supplied as a file, not a live duplex voice session. Evidence should distinguish speech transcription from speaker diarization, timestamps, language identification, non-speech sound analysis, emotion or prosody claims, and native audio-model input.

Record formats, channels, maximum bytes and duration, language limits, transcript editability, retention, model and plan requirements, and whether tools or sub-agents receive the original recording or only a derivative transcript.
