Takes an audio or video file (up to 24 MB) and returns the part between start_se
Takes an audio or video file (up to 24 MB) and returns the part between start_seconds and end_seconds as an audio file. The cut is sample-accurate because the excerpt is re-encoded rather than cut at the nearest frame. Optional fade-in and fade-out in seconds. If the end lies beyond the file, the excerpt ends with the file and this is reported. Output inline as base64, max 8 MB. Runs locally with ffmpeg; nothing leaves this machine. Fixed price per call.
