An Audio Speed Changer is a tool that adjusts how fast or slow an audio file plays. It changes the tempo of the track without necessarily affecting the pitch. For example, speeding up a song can make it more energetic, while slowing down audio can help with learning or transcription purposes.

No software installation needed. The tool works directly in your browser and supports both mobile and desktop devices. Just upload, modify, and download.
Changing speed affects how fast the audio plays. Changing pitch affects how high or low the sound feels. This tool focuses on adjusting speed while keeping the pitch the same, unless otherwise specified.
We value your privacy. All uploaded files are automatically deleted after processing. Your audio never gets stored or shared.
With the Bulk Audio Speed Changer, you can easily adjust the tempo of multiple audio files at once. It’s the perfect solution for professionals and casual users alike who want fast, reliable, and high-quality speed editing — all online and for free.
