Trimming a song or recording to the part you need
There are two ways to cut, depending on what you're keeping. Keep only discards whatever lies outside your selection, which makes it the fastest way to lift a 30-second clip from a long track. Cut, or the Delete key, deletes just the selected stretch and joins the two sides, ideal for dropping a false start, a cough or an ad break from the middle.
For precise edits, type times into the selection boxes down to hundredths of a second, then press Play selection with Loop switched on and nudge the numbers until the start and end land exactly where you want. Made a mistake? Undo with Ctrl+Z (⌘Z on a Mac).
Cutting a voice recording rather than music? Remove pauses takes out every gap longer than the length you set, anywhere from 0.3 to 3 seconds, in one go, while leaving a little breathing room so speech still sounds natural.
Making a ringtone
Pick 20 to 30 seconds, a chorus or a recognisable hook, select it, press Keep only, and add a short fade-out so it doesn't stop dead. Then:
- Android, export as MP3, copy it to your phone and choose it in the sound settings. Most phones let you add your own file to the ringtone list.
- iPhone, export as M4A, rename the extension from .m4a to .m4r, and keep it under 30 seconds: ringtones can run to 40, but alert tones stop at 30. On a Mac, drag the .m4r onto your iPhone in a Finder window to add it (on Windows, iTunes does the same job).
If the clip sounds quieter than your other tones, run Normalize loudness at −14 LUFS before exporting.
Fades, silence and clean joins
Both fades follow an equal-power curve, which sounds smoother to the ear than a straight-line ramp. They apply to your selection, or to the first or last three seconds when nothing is selected. Half a second is enough to soften a hard start; two or three seconds suits a song that should drift away.
Silence blanks the selected audio but leaves the timing alone, useful for removing a word while everything after it stays in sync. Every cut, trim and mute also gets a 5-millisecond ramp at its edges: too short to hear, but long enough to stop the click an abrupt join would make.
Making an intro or outro for a podcast or video? Cut 5 to 15 seconds of your theme, fade the end over two or three seconds, and export it once, ready to reuse in every episode.
Does cutting an MP3 reduce its quality?
To edit precisely, ClipLime decodes the MP3 into raw audio and encodes a new file when you export, so the result is one generation further from the original. Export at the source's bitrate or higher and that's very hard to hear.
Not sure what bitrate your MP3 has? Video Info shows it, it reads audio files too. 192 kbps is a safe default, and 320 kbps makes sense for a high-quality original. If you'll keep editing elsewhere, export WAV so later steps don't stack more compression. Need another format afterwards? The audio converter handles whole batches.
