Cutting against the waveform

Finding the start of a chorus by scrubbing is guesswork; finding it on a waveform is obvious, because the quiet passage before it is visibly quiet. That is the whole reason the display is there.

Cutting on a silence rather than mid-note avoids the click that an abrupt edit produces — a waveform that ends part-way through a wave leaves a step, and a step is heard as a click. A short fade solves it where a natural silence is not available.

Ringtone lengths

iPhone ringtones are capped at 30 seconds and have to be M4R; Android is more relaxed and accepts MP3. Either way, most calls are answered in the first ten seconds, so the interesting part should be at the start rather than building up to it.

Frequently asked questions

Why is there a click at the edit point?

The cut landed mid-waveform, leaving a step in the signal. Cut on a quiet moment or add a short fade.

Is there a length limit?

No — nothing is uploaded, so the limit is your machine’s memory rather than an upload cap.

How long can an iPhone ringtone be?

Thirty seconds, in M4R format. Android accepts MP3 and is far less strict.
