Why are there frequent clicks on the edges of audio clips?
- Live Versions: 8 - 9
- Operating System: ALL
There are frequent clicks and glitches at the beginning or end of clips.
When a sample is cut so that its beginning or end doesn't correspond to a zero crossing, a discontinuity in the waveform amplitude might happen.
This provokes glitches, pops or click sounds.
To avoid this problem in the Arrangement View, you will need to activate 'Create Fades on Clip Edges' in the Record/Warp/Launch pane of Live's Preferences.
A short (up to 4 ms) fade will be applied to the clip start and end to avoid clicks.
In the Session View, these 'declicking' fades can also be applied via the Clip Fade button, from the clip view.
The zero-crossing is a horizontal line in a waveform that shows where the waveform has an amplitude of 0 dB.
Another result of enabling the 'Create Fades on Clip Edges' option in Live's Preferences is that adjacent audio clips in the Arrangement View will get crossfades of 4 ms automatically. These can then be edited like manually created crossfades.
Additionally, at the beginning and the end of audio clips, they serve as adjustable volume fades.
To access the fades for clips in an audio track:
- 'Unfold' the track by clicking the button next to the track name.
- Select 'Fades' in the Fades/Device chooser.
- Click and drag the fade handle to change the length of the fade.
- Click and drag the curve handle to change the shape of the fade's curve.
