Audio Cutter Features Built Around the Cut
Audio cutter for files and videos
Use one audio cutter for MP3, WAV, M4A, FLAC, OGG, WebM, and video files. Upload a screen recording, clip, lecture, or short video and trim only the audio track.
Waveform audio cutting
Drag the handles on the waveform or type exact start and end times. The selected range stays visible while you make the cut.
Fade controls for cleaner cuts
Fade in and fade out are built into the audio cutter, so clipped music, voice notes, and video soundtracks can start and end smoothly.
