Sonoris has released Multiband Compressor, a versatile multiband compressor suitable for mastering or mixing.

Sonoris Multiband Compressor

It has three independent frequencybands followed by three compressors based on the Sonoris Compressor. The three bands are created with special designed filters to avoid phase cancellation problems. These filters are known as Linkwitz-Riley crossover filters and have a very natural, analog like quality. By design they mix back flat. Unlike linear phase filters they don’t introduce delay and are more efficient in use.

Transparency can be achieved by selecting auto-release and opto envelope emulation together with two soft knees. If a more warm sound is needed you can for example choose RC envelope emulation with a harder knee.

Multiband Compressor features

  • Phase correct Linkwitz-Riley crossover filters.
  • Wide crossover ranges.
  • Ratio ranging from 0.5:1 to infinity for compression, expansion and limiting.
  • Attack ranging from 0 msec to 1 sec. Totally clickfree, even at low values.
  • Selectable auto-attack on each band.
  • Release ranging from 1 msec to 5 sec.
  • Selectable auto-release on each band.
  • Threshold ranging from -60 dBfs to 0 dBfs.
  • Very flexible knee setting from hard to soft in 100 steps.
  • A second knee that enables the compressor to adjust the ratio back to 1:1 above the threshold. Also adjustable in 100 steps from hard to soft knee.
  • Two envelope types, RC and Opto.
  • supports 4 modes:
    • Normal, sidechain signal is the sum of left and right.
    • Highest, sidechain signal is the highest value of the left and right channel, for multiband limiting.
    • Left channel only for use with the Sonoris MS Codec plugin.
    • Right channel only, as above.
  • Output section limiter with limiter-action dependant light.
  • Mousewheel support, including global when holding the control key.
  • The gain transfers are shown graphically in real-time.
  • Three high resolution gain reduction meters.
  • Make up gain ranging from – 25 dB to + 25 dB.
  • Four level meters.
  • Track following.
  • Full automation possible.
  • Controls can be adjusted simultaneous for all bands.
  • Low CPU load.
  • Settings can be saved.
  • 64 bit integer math, except for the crossover filter code.
  • TPDF dither is used to convert the 64 bit signal back to SAW format. The dither is generated in assembly language.

The Sonoris Multiband Compressor for Windows and Mac (VST/AU/RTAS/AAX) is available for purchase for 249 EUR. It is 50% off during the NY AES, until November 2nd, 2015.
