5.1.9 Effect morphing

This dialog within the Audio File Workspace allows you to gradually mix two audio ranges

that have different effects/processing applied to them.

Effect morphing allows you to smoothly "morph" or blend from one effect to another, or from

an unprocessed audio segment to a processed audio segment. Effect Morphing always

involves two audio ranges. Normally, these are two versions of the same audio range, of

which one is unprocessed and the other processed.

Effect morphing works by using WaveLab's Undo buffer to mix a copy of the processed audio

with the unprocessed version. You can also use any other bit of audio from the application's

clipboard that has the same length as the one you wish to morph with.

To set up a basic effect morph, proceed as follows:

1. Start by making a selection range over the time you wish the effect morphing to take

place.

2. Now process this range using any Master Section effect(s), or use some other off-line

processing. You cannot use processing/effects that alter the length of the selection,

e.g. time stretching.

3. Open the Effect Morphing dialog by choosing Edit>Effect Morphing....

4. Adjust your envelope points over time between 0% and 100%. This will determine the

level and direction of the morph. For example, starting at 100% and ending at 0% will

fade out the effect you just applied.

5. Choose "Unprocessed selection" for this example. As mentioned previously you can

also use any audio of the same duration from the clipboard.

6. Click Apply to apply the Effect morphing.

You can access this dialog in the Audio File Workspace via Edit > Effect morphing....

5.1.10 Loudness distribution

This dialog allows you to measure the most frequent loudness values found in an Audio File

(this is not the same as average loudness). The graphic peaks found by the analysis represent

these values.

The tool gives an answer to the question: "How often does a given loudness (vertical scale,

in dB) appear in the whole ﬁle?". The percentage ﬁgure is relative to other peaks. Some

simple examples:

1. If, for instance, you have a sine of 0 dB / 2 second followed by a sine of -6 dB /

2 seconds. This means the global audio material has as much 0 dB material as - 6dB

material: you will see 2 peaks (0 / -6 dB), each at 100%.
