RIAA is a free equalizer VST, Audio Unit plugin developed by vacuumsound. Compatible OS(s): Windows 64b, macOS.

The RIAA – Phono Equalization plug-in provides normal and inverse RIAA equalization. It thus can be used for record playback or vinyl cutting purposes. Another nice trick is to use it to simulate certain ‘vinyl sound effects’ by applying the inverse RIAA curve to your signal and after running it through a compressor converting it back to flat.

It works at the standard sample rates from 44.1kHz up to 96kHz.


  • Level: Level adjust +/- 20dB.
  • RIAA: select between regular (playback) and inverse curve.

The download link goes to a 3 year old site in German which does not have any plugins or download links. In the KVR forum someone asked about this and was given a second URL that also goes to the same bogus German language site.
