What are the limitations of using ChatGPT for audio?

ChatGPT's audio limitations are concrete: upload size and length caps that force long recordings to be split, no speaker diarization, unreliable timestamps, no live listening to calls or rooms, and processing that happens after upload rather than in real time.

When ChatGPT is not transcribing at all, the cause is usually one of those caps, an unsupported file format, or a temporary feature restriction on the account tier.

It is a chat assistant that accepts audio, not an audio pipeline. For one memo, the difference never shows. For recurring recordings, voice notes, meetings, interviews, the missing pieces, batch handling, speaker labels, direct capture, are exactly the pieces that matter.

A purpose-built audio notes to text flow has those pieces.
