I have been reading this forum for a while, and have also searched on this issue, so am aware of previous recommendations (well the ones I could find anyway) The shortlist I seem to have come up with looks something like this : Waves : http://www.waves.com/Content.aspx?id=207 LinEQ Sonnoris : http://www.sonoris.nl/ PSP : (Dead Link Removed) Eiosis : http://www.eiosis.com/aireq Sonnox : http://www.sonnoxplugins.com RNDigital : MIDI and I'm also aware of these : Soniqware : http://www.soniqware.com/products.htm Blue Cat : http://www.bluecataudio.com Voxengo : http://www.voxengo.com/product/curveeq/ I have read a lot about the advantages and disadvantages of linear phase eq, and there does seem to be divided opinion. The 'smearing' and 'pre-ringing' exhibited by Linear Phase being the main objection. Am I right in thinking I would be best off with a good linear phase eq for small adjustments, and a non-linear phase eq for extreme adjustments ? I currently use the Liquid Mix emulations for some of my eq'ing combined with the standard 8 band parametric eq in my host daw. What I'm looking for is an alternative 'workhorse' transparant eq for carrying out both severe and subtle cuts and boosts right across the spectrum during bothmixdown and mastering. I suspect this is too tall an order and I willneed to consider two eq's My Final question concerns the http://www.waves.com/Content.aspx?id=207 equaliser which mentions the concept of a resonant shelf. I'm not familiar with this concept, but have an emulation of this eq on my liquid mix. can anyone explain how and where this is useful ?
