audio convert
Takes an audio or video file and returns the audio in the requested format — MP3, Opus, Ogg Vorbis, AAC in M4A, WAV or FLAC — with selectable bitrate for lossy formats, sample rate and mono or stereo. Only the first audio stream is converted; the content is not altered otherwise. Input and output are measured with ffprobe and both are reported, including size change. Output inline as base64, max 8 MB. Runs entirely on this machine; nothing is sent to third parties or stored. Billing per.
