About Change Audio Speed
Change the playback speed of any audio file from 0.25x (quarter speed) to 4x (quadruple speed), entirely in your browser. The pitch is adjusted automatically to avoid chipmunk or slow-motion effects –voices sound natural at any speed. This tool is ideal for speeding up podcasts and lectures for faster listening, slowing down music for practice or transcription, or creating time-stretched audio effects. Supports MP3, WAV, OGG, AAC, FLAC, and M4A formats. Uses FFmpeg for local processing –your files never leave your device.
