Free browser-based audio tools for editing, converting, analyzing, and testing sound
Each utility solves a single task — convert, trim, compress, transpose, test, or analyze — so you never have to navigate a heavyweight editing suite.
Convert and export between MP3, WAV, M4A, FLAC, OGG, AAC, AIFF, WMA, Opus, AMR, ALAC, and WebM, including pulling audio out of common video containers.
Decoding, editing, and analysis happen on your device, so files are not uploaded and no login is needed.
Find BPM, song key, chords, and loudness, tune string and chromatic instruments, and generate printable chord charts.
