Phase rotation section
Phase Rotation makes peak levels of asymmetrical sounds lower, to protect the compressors, limiters and clippers.
This protects the compressors, limiters and clipper against certain types of sounds that can easily distort. Examples are voices (especially female voices) and trumpets. They are very asymmetrical, with big spikes in one direction, and if there's also a bass sound present they tend to suffer from intermodulation distortion.
Main Phase Rotation settings.
- Phase rotation
Enables Phase Rotation.
- At start of processing
Perform Phase Rotation before all other filters.
By default, Phase Rotation is performed just before the clipper. If this setting is enabled, it is moved to just before Natural Dynamics and the AGC.
At low latencies (1024 sampples and below), Phase Rotation is always done at the start of the processing chain.
Setting that control how Phase Rotation works.
This is difficult to set up, and requires a lot of tweaking. The red spiral display shows the effect of the settings, except for that you'll have to play a lot of difficult sounds through it and check how they look and how well the clipper handles it.
- Start frequency
Phase Rotation works on sounds above this frequency.
- Initial speed
Controls how abruptly Phase Rotation starts to work above Start frequency.
Lower values can cause a huge 'bump' in the phase response, which can be noticeable (some people even seem to like it).
The amount of "moving" sounds back and forward.
Smooths abrupt changes in the graph, and hence in the sound.
Low latency panel
Settings that affect phase rotator artifacts and delay in low latency modes.
These settings effect latencies at and below 1024 samples.
- Low Latency Look back
Amont of samples to look back to.
A higher value increases the CPU load, but reduces artifacts.
- Low Latency Look ahead (increases latency)
Number of samples to look ahead.
The number of samples to look ahead. This increases both CPU load and latency, but reduces artifacts.
Phase Delay section
Purposely introduce non-phase linear behavior.
Phase Delay can be used to make more 'boomy' bass sounds, which replicates the sound of certain analog processors.
Phase Delay Equalizer panel
Configures the Phase Equalizer.
