Overview

Chunk Audio is a browser app that uses ffmpeg.wasm to split audio files into 10-minute chunks and package them as a downloadable ZIP. Use it at chunkaudio.briansunter.com.

Why I Built It

When working with long recordings, it’s often faster to split source audio into predictable segments before transcription, analysis, or editing. Chunk Audio packages that workflow into a single repository.

Use Cases

  • Preparing long recordings for transcription pipelines
  • Creating smaller files for iterative AI processing
  • Simplifying manual review of large audio sources
  • Building repeatable batch workflows for audio preprocessing
