![]() ![]() Note the chorus-like artefacts during note sustains (particularly bad at 0:03) and the softening of the picking transients. To show what I mean, here’s an out-of-tune acoustic guitar recording Ex06.10: WAV/ MP3 play_arrow, and the same file which I have corrected as carefully as I can in Celemony’s Melodyne Editor Ex06.11: WAV/ MP3 play_arrow. Pitch Correction Side-effects: Although state-of-the-art pitch-correction engines such as Celemony’s Melodyne now offer enormous potential for pitch-correction, they still tend to produce unwanted processing side-effects when presented with transient, noisy, or polyphonic audio. Now listen to that same edit within the context of the mix, and notice how the strong masking action of the drum loop’s kick/hat downbeat completely conceals even such horribly clunky discontinuity in the vocal line Ex06.07: WAV/ MP3 play_arrow. ![]() Here’s a truly blood-curdling audio edit Ex06.06: WAV/ MP3 play_arrow, causing a big lump right in the middle of a vocal line. ![]() Masked Audio Edits: An often-overlooked method of concealing audio edits is to hide them behind other masking events in the production, as demonstrated by the following audio examples. Although the edit is still not completely inaudible in this case while the vocal is soloed, it’ll be more than good enough to pass muster when set against even the most basic backing arrangement. Adding a short equal-gain crossfade over just a couple of waveform cycles smooths the result even further Ex06.05: WAV/ MP3 play_arrow. ![]() Sliding the waveforms fractionally to line up their repeating cycles dramatically reduces the click, even without any crossfade Ex06.04: WAV/ MP3 play_arrow. At the moment the waveform is mis-aligned and without any crossfade, so you hear a big click. Matched-waveform Audio Edits: Here’s an example of the kind of mid-note slice point that can benefit from a matched-waveform edit Ex06.03: WAV/ MP3 play_arrow.
