Sonoris Audio Engineering has announced the release of the Sonoris Mastering Compressor (SMCP), a wideband mastering compressor in VST, AU and RTAS formats for Windows and Mac. It costs €199.

SMCP is an ultra clean compressor suitable for delicate material. No odd harmonic distortion that can be found in most compressors is present in the SMCP. To reduce residual artifacts the SMCP features upsampling of the audio up to 8 times. Transparency can be further enhanced by selecting auto-release and feedback detection together with two soft knees.

If a more aggressive behaviour is needed you can for example choose feed-forward detection with a harder knee. It can have some "character" if pushed. If needed, the audio can be warmed up with even harmonics with the flip of a switch.

Besides working on a full mix, the SMCP can also work in split mode on the individual L, R, M or S channels or anything in between, with the variable link. The sidechain for each channel has a selectable high-pass, band-pass and low-pass filter. This gives great flexibility and allows for creative enhancement of the audio.

Features:

• Ultra clean wideband mastering compressor.
• Ratio ranging from 1:1 to infinity for compression and limiting.
• Attack ranging from 0 msec to 1 sec.
• Selectable auto-attack.
• Release ranging from 1 msec to 5 sec.
• Selectable auto-release ranging from 0.5 sec. to 5 sec. program dependent.
• 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.
• Feedback and feed-forward detector types.
• Selectable high-pass, band-pass and low-pass sidechain filters.
• 4 processing modes:
  1. Mix Linked: sidechains linked with the RMS mix of the left and right channels.
  2. Highest Link: sidechains linked with the highest value of the left and right channel.
  3. Variable: sidechain linking is adjustable from fully linked to fully split.
  4. MS Split: sidechain signals split with the mid and side channels.
• Make up gain ranging from – 18 dB to + 18 dB.
• 2x, 4x, 8x or auto upsampling for even less artifacts.
