About this tool
Change playback speed by resampling; the pitch changes together with the speed.
How to use
- Choose the local file you want to process.
- Set the available options, then run the tool.
- Inspect the result and download the output. Your original file is unchanged.
Processing stays in this browser. Input codecs depend on browser support. Output is uncompressed 16-bit PCM WAV, not MP3 or AAC. Use files up to 25 MB, with decoded duration no more than 10 minutes and at most 30 million audio samples. This is simple interpolation resampling. It does not preserve pitch or provide a mastering-quality time stretch.
