Audio sample

Pull a fixed-length sample from any point in a longer recording.

Take a clip out of an audio file now No key, no code — 5 credits either way.

Pull a fixed-length sample from any point in a longer recording.

Extract a fixed-length audio sample starting at a given offset.

Input

Send a file object with base64 data_b64, its content_type and a filename. Accepted types: audio/mpeg, audio/wav, audio/ogg, audio/flac, audio/mp4.

The declared type is not trusted — the bytes are sniffed and a contradiction is rejected rather than corrected.

Response

The result carries your remaining balance alongside it, so you can track spend without a second call.

Cost

5 credits per call, whether it is run from the site or from the API — the credential differs, the price does not. A new account starts with 20 credits.

A rejected request still costs a credit: the authorizer decrements before the tool validates. A call rejected for a missing or invalid key is free.

Parameters

Generated from the endpoint’s own validation, so this is exactly what it accepts. A body field goes at the top level; an option goes inside options.
