Audio cutter - trim a song or recording on the waveform

Load the track, select the best 20-30 seconds, set Fade in to 0.5 s and Fade out to 1-2 s, and save as MP3 at 192 kb/s. A 30-second clip at that bitrate is about 720 KB (192 × 30 ÷ 8). Most Android phones accept an MP3 directly as a ringtone. iPhones need an M4R file: import the MP3 into GarageBand and export it as a ringtone from there.

Songs are protected by copyright, so cut them for your own private use only.

The waveform shows loudness over time: flat stretches are silence, tall spikes are drum hits or hard consonants. The cleanest cut lands in silence or just before a clear sound. Mark the section roughly on the waveform, then correct it with the sliders or time fields, which move in 0.1 s steps. The shortest possible clip is 0.1 s.

Fades can be set in 0.5 s steps up to 10 s, and never longer than half of the selected section. A fade in raises the volume linearly from zero; a fade out lowers it to zero. Even 0.2-1 s removes the click you hear when a cut lands mid-waveform.

The file is decoded to raw audio, trimmed and encoded again. WAV output (16-bit) adds no further compression loss. MP3 output is lossy, so pick 192-320 kb/s to stay close to the source; the bitrate menu offers 64 to 320 kb/s.

• One continuous section is kept per cut. To remove the middle of a recording, cut the two parts separately and join them with merge audio.
• The output is always MP3 or WAV - M4A, OGG and FLAC are not written back. Use the audio converter afterwards if you need another format.
• Tags and cover art are not copied.
• The whole file is decoded into memory, so recordings longer than an hour or two are best trimmed on a computer.

• Ringtone - 20-30 s, fades 0.5 s / 1-2 s, MP3 192 kb/s.
• Trimming a meeting recording - any length, no fades, MP3 96-128 kb/s.
• Podcast intro or jingle - 5-15 s, fade out 1 s, WAV for further editing.
• Sample for a presentation - 10-60 s, fades 0.5 s / 2 s, MP3 192 kb/s.

Cutting a scene from a film instead? Use trim video, or extract the soundtrack first with Video to MP3. All processing in this cutter stays in your browser, so private recordings never leave your device.
