What are the Audio Tools APIs?
The Audio Tools APIs are Pixazo's programmatic audio utilities — the audio operations you'd normally run in a desktop tool, exposed as simple API calls. Convert MP4 to MP3, or pull a clean audio track out of any video, through a dedicated endpoint on the same Pixazo API and authentication.
They're built to drop into an existing media pipeline: extract audio for podcasts, transcription, or archives automatically, at scale, without manual exporting. Each tool is in active development — open its page for the planned inputs, outputs, and options.
The Audio Tools APIs at a glance

How do the Audio Tools APIs work?
- Authenticate with your Pixazo API key (Bearer token).
- Send a video (or audio) URL or upload with your target format, sample rate and channels.
- The job runs asynchronously — poll its status or receive a webhook.
- Download the extracted audio; your source file is never modified.
Common use cases
- Podcast repurposing — turn video interviews into MP3 episodes.
- Transcription prep — extract a clean track to feed the Speech to Text API.
- Archiving — store meeting and webinar audio separately from heavy video.
- Audio datasets & search — batch-convert a video library to MP3.
