What is Audio Splitter?

Audio Splitter lets you cut an audio file into multiple segments at precise timestamps. Define split points visually or by entering times, then export each segment as a separate file.

The decoder reads MP3, WAV, OGG, FLAC, AAC, M4A, and WebM, draws the waveform on a canvas, and lets you set split points by clicking the waveform or typing timestamps to the centisecond. Choose a chunk length to place markers automatically. Each segment exports as WAV at the original sample rate, or as MP3 for a smaller file; the full set zips into one download.

How to use

1. Upload an audio file and view the waveform display
2. Add split points by clicking on the waveform or entering exact timestamps
3. Pick WAV or MP3, click Split, preview each segment, and download them one by one — or grab all segments at once in a single ZIP.

When to use

• Cutting a live set or DJ mix into individual tracks before uploading to a music platform.
• Breaking a long podcast episode into chapter clips for social media teasers.
• Slicing a multi-track field recording so each take becomes its own file.

Result

A DJ splits a one-hour live set recording into individual tracks at the transition points for separate uploads to a music platform.

FAQ

Will the segments lose audio quality compared to the original?

Each segment is rebuilt from the decoded PCM samples and written as a WAV at the source sample rate, so the cut is lossless. If your input was MP3, the WAV holds the same audio that the MP3 decoded to — no second round of compression.

How precise are the split points?

The timestamp input accepts centiseconds (mm:ss.cc), and the cut snaps to the nearest audio sample at the chosen sample rate. At 44.1 kHz that is roughly 0.023 ms per sample, well below what you can hear.

What output format do I get?

Pick WAV or MP3. WAV is uncompressed, so the cut is exact and the file opens in any audio tool. MP3 re-encodes each segment to a smaller, easy-to-share file at about 190 kbps. Both run right on your device.

Is there a limit on how many split points I can add?

There is no hard cap. The interface stays smooth past a hundred points, though placing them on the waveform gets fiddly at that density. For evenly spaced clips, use the 2 / 3 / 4 / 5 / 10 equal-parts presets — one click places the split points for you.

How big a file can I load?

The waveform is held in memory as 32-bit floats, so a one-hour stereo file at 44.1 kHz uses about 1.4 GB. Desktop browsers handle podcast-length files fine; on mobile, stick to under 30 minutes or compress before loading.
