Play the file, mark where each new clip should start, and export every part at once in a single ZIP download.
The Audio Splitter divides one long recording into several files. Use it for a recorded show you want as separate tracks, a lecture split into topics, a podcast broken into segments, or a long voice note cut into pieces small enough to email or upload.
You decide where the cuts go: place markers by ear while the audio plays, let the tool detect silent gaps between songs or topics, or ask for equal-length parts. Every part is previewable before you download, and all of them arrive together as a ZIP.
Markers are stored as times; on Apply the buffer is sliced between consecutive markers and each slice gets a 1 ms edge fade to avoid pops. The “Find silent gaps” option runs a 10 ms-resolution RMS detector with 3 dB hysteresis (so brief dips in a note do not count) and puts a split in the middle of every gap of at least 0.5 s below −42 dBFS.
All parts are encoded separately in your chosen format and packed with the store (uncompressed) ZIP method — MP3 and WAV barely compress, so this is quick and the ZIP is the same size as the files.
Split a continuous capture into one file per song.
Make a file per topic so students can jump to what they need.
Break a long file into chunks under a size limit.
Divide a long narration at the chapter breaks.

Splitting itself is lossless. Choose WAV to avoid any re-encode, or MP3 at 256–320 kbps for near-transparent copies.
As many as you have markers — hundreds work fine.
Yes; tap the waveform to place the playhead, then add a split.
As many as you like — add as many split points as you need before exporting.
Browsers often block multiple automatic downloads at once, so all parts are bundled into a single ZIP for a reliable, one-click download.
Yes — tap the × on any marker chip before exporting.
