MP3 cutter
Trim a recording, keep one section of a song, or cut the silence off the ends. Drag the start and end on the waveform, add a fade if you want one, listen to the piece, and save it as MP3 or WAV. Everything runs in your browser.
This page needs JavaScript for the tool itself. Open it in a browser to use it.
How it works
Drop the file on the page. Your browser decodes it and draws the waveform. Drag on the waveform, use the sliders, or type times to a tenth of a second to set where the piece starts and ends. Play the piece to check it, then save. The encoder runs in a background thread and the file is offered for download from your device.
Fades
A fade in and a fade out of half a second remove the click a hard cut can leave. Two or three seconds make a natural ending for a section taken from the middle of a song. Fades are applied to the saved file and to the preview, so what you hear is what you get.
MP3 or WAV
Save as MP3 for a phone, a message or a website; 192 kbps is a good default and 320 kbps the best MP3 can do. Save as WAV when the piece goes into an editor or a session, so it is not compressed a second time. The sample rate and channels of the source are kept.
What the browser can read
MP3, WAV, AIFF, FLAC, OGG, M4A and the audio track of MP4 and MOV video. The whole file is decoded in memory, so a phone manages a typical song or episode and a laptop manages hours of audio.
From the label's own toolbox
BeatRootRaga is an independent label. Cutting a reference section out of a long take is daily work, and this cutter is the one the label uses, put online for anyone. To convert a whole file rather than a piece, the audio converter is next door.

All guidesRaga Yaman (Kalyani)
Yaman is a seven-note Hindustani raga, a melodic framework, with a raised fourth; Kalyani shares its scale but uses different phrasing and ornaments. Traditionally associated with evening, Yaman can sound serene or devotional; hear its character through Ni Re Ga, starting below Sa, the home note.
Thaat and melakarta explained
A thaat in Hindustani music and a melakarta in Carnatic music are seven-note parent scales used to organise ragas, the melodic frameworks musicians perform. Hindustani music uses 10 practical categories, while Carnatic music uses 72 allowed scale combinations; these help identify note relationships, not a raga’s phrases or character.
Raga vs scale: what Western musicians get wrong
A raga adds rules for movement, emphasis, identifying phrases and ornamentation to a scale or mode, a scale with a home note. Producers lose its identity when they treat it as a note list, ignore its tuning and phrasing, or let changing chords reshape the melody’s meaning.
Raga Kirwani (Keeravani)
Kirwani is a raga, a musical framework, using C D Eb F G Ab B when Sa, its home note, is C. Heard in concerts, light classical music and film scores, it often suggests longing; listen for Ab rising to B, then C.
Raga Hamsadhwani
Hamsadhwani is a five-note raga from the Carnatic tradition, using Sa, Re, Ga, Pa and Ni, or C D E G B with Sa as C. It often opens Carnatic concerts; hear its bright, devotional character by playing the notes over C and G, noticing B resolving to C.
Raga Charukeshi (Charukesi)
Charukeshi comes from Carnatic music and uses Sa, Re, Ga, Ma, Pa, lowered Dha and lowered Ni. Heard in concerts, light music and film scores, its bittersweet character is clearest in the descent from lowered Ni through lowered Dha to Pa.
Questions people ask
Is the MP3 cutter free, and is my file uploaded?
Free, no account, and nothing is uploaded. The file is decoded, cut and encoded inside your browser.
How precise is the cut?
To a tenth of a second by typing, finer by dragging on the waveform. The cut is made on the decoded audio, so it lands exactly where you set it, not on the nearest MP3 frame.
Does cutting an MP3 lose quality?
The piece is decoded and encoded again, so it goes through one more MP3 pass. At 192 kbps or more the difference is not audible for most listeners; save as WAV if you want to avoid it entirely.
Can I join pieces or cut several sections at once?
Not on this page. It cuts one piece per file. Run it again for another piece.
Can I use it for a video?
Yes, for the sound: drop an MP4 or MOV and the audio track is cut. The video itself is not changed.
