Audio Editor Shipped

Some files are not wrong, just badly cut: eight seconds of silence at the front, a DJ drop you never wanted, a minute of crowd noise on the end. Until now that meant leaving your library for an audio editor and hoping it gave the file back intact.

Edit Audio… in the Tracks & Tags bar opens the selected track as a waveform. Set an in and an out point, listen to exactly what you would keep, and save — over the original, or as a second copy filed beside it.

What it does

• No re-encode. The cut is a stream copy, so a 320kbps MP3 stays a 320kbps MP3. Your tags and embedded cover art come through untouched.
• Detect Silence. Snaps the selection just inside the leading and trailing silence, so topping and tailing a rip is one click.
• Zoom for precision. The +/− keys, a pinch over the waveform, Fit and Zoom to Selection, with a scrubber for moving through the track while zoomed in. The waveform is sampled finely enough that zooming reveals real detail rather than stretching the same columns.
• Full transport. Play/pause, skip back and forward 5 seconds, jump to the start or end, and a fast-forward cycling 1× → 1.5× → 2× → 4× that scans at real speed rather than skipping.
• A droppable marker. Drop a marker with M and return to it with ⇧M while you hunt for the right cut — separate from the playhead, and drawn separately on the waveform.
• Audition either side. Playing from inside the selection stops at the out point, so you hear what you'd keep. Playing from past it runs to the end of the file, so you can hear the tail before committing to losing it.
• Keyboard control. ←/→ step by 0.1s (⇧ for 1s, ⌥ for 0.01s), ⌘←/⌘→ jump to the in/out points, Home/End to the track boundaries, I/O set the trim points, Space plays.
• Two ways to save. Save In Place overwrites the file and keeps a timestamped backup of the original. Save As New File writes a second copy, registers it with Serato, and files it next to the original in every plain crate that holds it.

How to use it

1. Select a track

   In Tracks & Tags, select one track and click Edit Audio….

2. Set the in and out points

   Drag the handles, or use Detect Silence and nudge from there. Zoom in for a precise cut.

3. Listen to it

   Play from inside the selection to hear the keeper, and from past the out point to hear the tail you're cutting.

4. Save

   Overwrite the original, or save a second copy. Serato has to be closed either way.
