#MULTI BAND VS SINGLE BAND COMPRESSOR GENERATOR#

The вЂalways activeвЂ™ crossovers impart a sound that is desirable sometimes, but in the pursuit of вЂtransparencyвЂ™ this is clearly not an ideal signal path.Дynamic Equalizers instead pull the crossovers out of the signal path and only use them to determine signal level for a given band, then that level drives an envelope generator that adjusts the level of a filter. вЂњTrueвЂќ multiband compressors have their place. Dynamic Equalizer - Steep crossovers do not impart any вЂsoundвЂ™.Multiband Compressor - Steep crossovers impart a consistent, and audible, phase rotation at all times.Multiband Compressor - Only one layer of interaction.Дynamic Equalizer - Filters and bands in detection signal could be altered separately, if designed to allow that access.When the processor is at rest, the passing signal is untouched. Multiband Compressor - Crossover filters always are in effect on the signal, even when the processor is вЂat restвЂ™.Дynamic Equalizer - Crossover filters never touch the signal.Multiband Compressor - The dynamic processors changes the amplitude of the signal that passes through.Дynamic Equalizer - The dynamic processors adjust the amplitude of filters in the main signal path.Multiband Compressor - Signal that passes through the crossovers is the same signal that passes through the output.Дynamic Equalizer - Signal that passes through the crossovers does not pass to the output.LetвЂ™s explore the difference between whatвЂ™s generally called вЂњMultiband compressionвЂќ and вЂњDynamic EqualizationвЂќ. The above investigation is not an indicated of poor quality processing. Multiband Compressor vs Dynamic Equalizer (Click for larger image) Is it processing the left/right differently or is that some sort of bug? Amplitude response - all bands - Second attempt - Second attempt - Second attempt I did see something else interesting here thoughвЂ¦ Those two colours are left and right response. (IвЂ™ve had someone ask this about another product) ThatвЂ™s exactly what filters boil down to though, so you can dismiss that notion. You may get the idea that itвЂ™s not using вЂdynamic filtersвЂ™, but instead mixing in band-limited вЂbandsвЂ™ of the original signal. It is clear here that the GUIвЂ™s display once again does not match what is measured. All of these tests are relatively unreliable other than looking at them relative to each other (does the testing method change the result?). What have we learned from the test? Not much really. The test here is using the same settings as previously. I added this test after discovering more about this product). Since this is a dynamic processor, it may not be a valid way of measuring things. IвЂ™m using a different measurement system here that utilizes an impulse for measurement. Amplitude response - all bands - Failed attemptДЄmplitude response, all bands, again.

Amplitude response - What is the plugin doing in general?ДЄ quick play with the controls shows no zipper noise and no major GUI glitches (besides tooltips sticking).

Phase response - does the plugin impart a вЂњsoundвЂќ due to the crossovers when itвЂ™s doing nothing?.

There are a few things we need to check first:

Amplitude response - all bands - Third attempt.

Amplitude response - all bands - Second attempt - Second attempt - Second attempt.

Amplitude response - all bands - Second attempt - Second attempt.

Amplitude response - all bands - Second attempt.Amplitude response - all bands - Failed attempt.IMPORTANT! IMPORTANT! After reading this article, please read the followup article. If you feel that this has possibly coloured my review, please let me know. I DID NOT PAY FOR THIS PRODUCT I am both a beta tester and received an NFR review copy. What follows are the results of my investigation and general thoughts. Harrison AVA Multiband Compressor is out, and I spent some time looking over it and using it in some projects.
