Split Audio Online

• Split audio at the playhead

  Drag the playhead to the moment a section ends and hit Split. The clip divides into two independent segments with nothing removed, so you can keep cutting until every chapter, song or answer sits in its own block. The waveform makes gaps, applause and loud sections easy to spot, and you can zoom in for precision.

• Silence detection marks the break points

  The silence remover scans your recording and cuts at pauses automatically. Long recordings usually break at silence anyway, between songs, questions or chapters, so most cuts land where you would have put them. Review each one afterwards and keep or discard segments as you like.

• Cut by transcript instead of scrubbing

  EchoWave transcribes your audio with AI, then lets you edit the recording by editing the text. Find the sentence where an answer ends, cut there, and the timeline follows. It is the fastest way to split an interview when you know what was said but not when it was said.

• Keep, delete and reorder segments

  After splitting, each segment is a separate block on the magnetic timeline. Delete the parts you do not want and the rest close ranks automatically, with no dead air left behind. Drag segments around if the export should play in a different order than it was recorded.

• Export one piece at a time

  EchoWave renders one file per export. Keep the segment you need on the timeline, export it, then undo your deletions and repeat for the next piece. The free plan exports an HD MP4 with a small watermark badge; audio-only MP3 and M4A come with Basic, WAV and FLAC with Pro, and everything renders on a cloud render farm rather than your machine.

• Split the audio inside a video

  Drop in an MP4, MOV, WebM or AVI and cut it exactly the same way, then export the result as audio only. If you want to keep the picture, the split video page covers that workflow, and the full audio editor handles fades, speed changes and mixing.

• Ask Echo to make the cuts

  Echo is the AI assistant built into the editor, with 39 editing tools it can run from a chat panel. Tell it to split the recording at every question, or cut at 12:40, and it does the clicking for you. It saves a checkpoint before big changes, so one click reverts everything.

1. 1

   Upload your recording

   Go to echowave.io and drop in your file. MP3, WAV and M4A all work, and so do videos like MP4 or MOV when the audio lives inside one. The recording lands on the timeline with a waveform you can zoom into.

2. 2

   Place the playhead and split

   Play the recording, pause where a section ends, and click Split. Repeat at each boundary. If pauses mark your sections, run the silence remover first and let it place the cuts for you.

3. 3

   Keep the piece you want

   Delete every segment except the one you are exporting. The magnetic timeline closes the gaps, so what remains plays as one continuous piece. Preview it to check the cut points sound clean.

4. 4

   Export, then repeat for the next piece

   Export the segment free as an HD MP4 with a small watermark badge, or go audio only with MP3 and M4A on Basic, WAV and FLAC on Pro. For multiple pieces, undo your deletions and repeat, one export per file.

• Podcast chapters

  Split a full episode into chapters or standalone segments to republish or quote. The transcript view helps you find topic changes without listening back at full length.

• Live recordings into songs

  Turn a continuous concert, DJ set or rehearsal recording into individual songs. Gaps between tracks show up clearly on the waveform, and silence detection can place most of the cuts for you.

• One answer from a long interview

  Pull a single quote out of an hour of tape. Search the transcript for the phrase, split around it, and export just that clip.

• Lectures into lessons

  Break a recorded class or webinar into lesson-sized files students can actually find. Consistent pauses between topics make silence detection especially effective here.

• Clips for social audiograms

  Split out a strong 30 second moment, then style it with one of 30+ music visualizers and AI captions before exporting a video for TikTok or Reels.

• Voice memos and field recordings

  One phone memo often holds five separate ideas. Split them apart so each melody, lyric or observation becomes its own file you can name and find later.
