How to trim an MP3 or WAV online

Choose the section

To follow the steps without using your own music, press Cargar audio de ejemplo (load sample audio). The beat lasts 16 seconds. Leave the start at 0 and type 8 as the end to keep its first four bars. Then you can repeat the process with your own file.

Open Recorte individual (single trim) and press Abrir archivo (open file), or drag your WAV or MP3 onto the upload area. QuickEdit draws the waveform and fills in the end with the available length. You can use the Al pulsar la onda (on waveform click) selector to set an edge by hand and refine it with the Inicio (segundos) (start, seconds) and Final (segundos) (end, seconds) fields. Confirm changes with Enter or by leaving the field.

If the sound you want to keep starts at 12.40 s and ends at 27.88 s, type those two values. The edit will last 15.48 s. Listen before exporting to check that the first beat comes in whole and that the end lands where you expect.

Adjust the edges

If a cut falls in the middle of a note and you hear a click, try a fade of a few hundredths of a second. Be careful with the start when the section begins with percussion. Change the Ganancia (dB) (gain) if you need to change the level of the whole section. You can compare two settings with Deshacer (undo), Rehacer (redo) and Escuchar edición (play edit).

Download the trim

Press Descargar WAV (download WAV). QuickEdit saves a 24-bit, 48 kHz copy and keeps the channels of the source. To keep the trim, download the WAV before closing the page. If you need the section as several tracks sound together, select it in session mode and export that part of the mix.

If you are delivering several cuts for a ceremony, organise the wedding entrance and exit music with one WAV per cue.
