Audio Tools
Trim, join and adjust MP3 or WAV recordings, then export privately as MP3 or WAV.
Choose MP3 or WAV files. Drag the waveform handles to keep or delete a section, add fades, arrange clips and export one joined recording. Your audio stays on your device. A small MP3 encoder downloads from this site only when you choose MP3 export.
Up to 10 files, 50 MB total and 10 minutes combined decoded audio. Large recordings can exceed your device’s memory. MP3 export is lossy; keep your originals.
Volume above 100% can cause distortion. Output is stereo, 44.1 kHz. Enter precise trim times as mm:ss.ss, or drag the red waveform handles. Fades last up to half a second.
MP3 encoding uses LAME via lamejs 1.2.1 (LGPL). License · Library source
