We very generally recommend that the multiband limiter release times be operated
with a tapering slope of about 150 milliseconds on the lowest band to approximately
30 milliseconds on the highest band as shown below. This is not a hard and fast rule,
but a general suggestion that will sound good on a wide variety of program material.
Your ears should always be the final judge on any setting.
Release Time Note:
The eight band limiter’s Release times may be adjusted all the way down to
3 milliseconds, which is far too fast a setting for frequencies below about 1kHz. The
reason we allow this to be done is that certain audio textures, especially in the bass
region, may be created by purposely operating the lower frequency limiters with
extremely fast release times.
In effect, such drastic settings create harmonic and narrow-band IM distortion. But
because the resulting distortion is constrained to the quite narrow frequency bands of
the VP‑8
iP
’s multiband limiters it is possible to create aesthetically pleasing “warmth”
on the low end without blatant and irritating distortion.
This type of adjustment is usually done only to create an effect. It is done only on the
lower three or four bands, it must be done with great care, and we do not recommend it
as standard operating procedure. Please contact us for assistance or advice if you would
like to experiment with this capability and are not familiar with how best to use it.
Final Equalization Screen
There is no post limiter EQ available in either the MP3/AAC<48K or
MP3/AAC>48K modes.
