Hallo Alexey,

very nice stuff, hard to find such good sounding plug-ins.

One question, does the Polysquasher mastering compressor work like a multiband-compressor to balance the frequency spectrum of the signal ?

Do I sill need a mulibandcompressor in my masteringchain if I use Polysquasher ?

Polysquasher is not a multi-band compressor: that is, the audio is not divided into several bands.  The balancing Polysquasher does is not exactly controllable - it simply adjusts the audio in a preferrable way.  Polysquasher is best used right before the limiter in the post-processing chain.

If you need some more control over audio spectrum you should definitely use some multi-band compressor.  I believe Voxengo Soniformer is a nice choice since it is hard to destroy the mix with it due to its design and control layout.  But of course you may use any other multi-band compressor.
