Q3D free eq plugin has a total of six very wide bands. The first four act as a peak filter with fixed cutoff values of 10 Hz, 40 Hz, 160 Hz and 650 Hz. The fifth parameter is a shelving filter. These five parameters can be raised or lowered by up to 15 dB.

The sixth parameter Air works as a Hi-Shelf filter. This allows not only to increase the presence and the upper-frequency components but also to choose between the five predefined limiting frequencies of 2.5 kHz, 5 kHz, 10 kHz, 20 kHz and 40 kHz.


The virtual equalizer in rack format is extremely attractive and is very friendly with your CPU.


  • Extremely High Processing Efficiency.
  • Proprietary topology which is optimized for low latency, low noise, and high dynamic range.
  • Supports sampling frequencies up to 384 kHz.

Q3D 6 band equalizer plug-in supports VST, VST3, AU and AAX plugin formats, and best of all it’s FREE!
