A free MP3 cutter and audio trimmer: cut and trim any song with sample-accurate precision. Nothing is re-encoded, so the audio you keep is untouched.
The audio cutter — equally an MP3 cutter, song cutter, or audio trimmer — trims a file down to the section you want, accurate to the individual sample: tens of thousands of possible cut points per second, rather than the coarse frame grid video editors work on. Cutting removes what you don't want without re-encoding what you keep, so the audio that survives is bit-for-bit identical to the source.
It's the tool for pulling a quote out of an interview, making a ringtone, topping and tailing a recording, or grabbing a loop to sample. The one thing that separates a clean trim from an audible click is where the cut lands: end on a zero crossing or a natural pause and the edit disappears; slice through the middle of a waveform and the sudden jump becomes a click. How to cut audio without losing quality shows the difference. For stripping many gaps at once, use the silence remover.
Our trimmer extracts precise start and end times down to the exact audio sample, rather than rounding to the nearest video-style "frame" the way some editors do, which matters if you're cutting tightly around a word, a breath, or a musical hit. The trim start and end sliders move in 0.1-second steps — click a slider to focus it, then use your keyboard arrow keys for even finer nudging once you're close to the exact point you want. This level of control is useful for trimming a ringtone, isolating a short clip for social media, or cleaning up dead air at the start or end of a recording. Always preview before downloading, since a trim point that looks right on the waveform can still land a fraction of a second off from where it actually sounds right.
Absolutely — click the "Play Selection" button to hear only your currently trimmed segment before committing to a download. The player automatically seeks to your start point, plays through, and pauses right at your end point, so you get an accurate preview of exactly what you'll download. This is the easiest way to catch a trim that's cutting off the first syllable of a word or clipping in too early on a beat, before you've wasted time downloading and checking manually. If the segment doesn't sound right, just adjust the sliders and hit Play Selection again — there's no limit to how many times you can preview before you're happy with it.
Not at all — your trimmed segment is extracted directly from the original decoded audio and saved as a standard high-fidelity file, with no re-compression step in between. Because there's no lossy re-encoding involved, you can trim the same file multiple times to fine-tune your cut without any generational quality loss building up. That said, the output can only be as good as what you start with — trimming a heavily compressed, low-bitrate MP3 won't restore detail that was already lost when that file was first encoded. For the best results, start from the highest-quality source file you have available, especially if you plan on doing further editing afterward.
Yes — it's an MP3 cutter, a song cutter, and a general audio trimmer in one. Load an MP3 (or WAV, FLAC, M4A, OGG, and more), set your start and end points on the waveform, preview the selection, and download just that part. "MP3 cutter", "song cutter", and "audio trimmer" all describe the same job this tool does: keeping the section you want and dropping the rest, without re-encoding what you keep.
