SlickEQ more tips & tricks

Check also tips & tricks by Herbert <http://varietyofsound.wordpress.com/2014/07/07/tipstricks-with-slickeq/>

Part 1. SlickEQ free version

1.1. Listen to your favorite music through SlickEQ

SlickEQ is good enough to be used as hi-fi equalizer. On Windows you can use <George Yohng’s VST Wrapper for Foobar2000 player> to listen to your favorite music through it!


  1. Set output level to -3 dB to prevent clipping
  2. Set “calibrate” to 0 dB to leave harmonics added at the edge of hearing threshold
  3. Don’t over-EQ the music. Keep gain values below 3 dB.


1.2. Save your CPU cycles when mixing!

SlickEQ is a bit CPU heavy. We performed optimizations for Sandy Bridge architecture but for modern energy saver simplified CPUs in thin notebooks or for old CPUs the CPU load may be too high.


  1. Turn EQ Sat off and set Out Stage to Linear. If non-linear processing is not used, SlickEQ may consume 3 times less CPU cycles! If you already have some saturation on a track you may choose to turn off the saturation in SlickEQ.
  2. Turn stereo mode to “Mono” if you’re processing a mono audio signal. In this case SlickEQ will consume 2 times less CPU cycles! NOTE: some DAWs report that they have a mono track and in this case stereo mode button is grayed and SlickEQ operates in mono mode automatically.

Nova-67P: 88.2/96 or higher sample rates related update (Mac/Windows)

Nova-67P v1.0.2 update

Fixed a bug with UI freeze when working on 88.2/96 or greater sample rates:


Please report me your experience about this fix.


Nova67-P Mac version maintenance update (v1.0.1)

List of bugs fixed:

  • bug that prevents usage of the plugin on mono tracks in Logic
  • bug with occasional hang on preset change in AU 64-bit version
  • possible crash for AU version

Also please note that hot-keys in Mac version operate a bit differently than in Windows one:

  • use Command + Click instead of Ctrl + Click to reset parameter to default value
  • use Ctrl + Click to open filter’s context menu if you have a single-button mouse




Both Mac versions of Nova (VST & AU) hang if 88.2 or 96 kHz sample rate used in the project. I didn’t check 88.2/96 on Mac before… Okay, I’m going to fix it!

Nova-67P and parallel equalizers explained

How do parallel equalizers work? The signal is passed through band-pass filters, gain applied and then the result is summed with the dry signal.

simple parallel equalizer

band-pass + dry signal = bell shape
low-pass + dry signal = low-shelf
high-pass + dry signal = high-shelf

What is so special about parallel equalizers in digital world? I like the way how bands interact with each other! Check the picture. There’s a typical serial equalizer on the left (SlickEQ GE). There’re 2 bands, 1 kHz and 2 kHz with +6 dB boost on both. In serial equalizers close bands tend to “stick” to each other and in parallel equalizers this effect is less prominent. The difference may be very subtle but for me a typical parallel equalizer provides greater bands separation especially in a busy midrange, which is very suitable for mixing tasks.

serial equalizer vs. parallel equalizer

Parallel equalizers and cuts. Most parallel equalizers operate in a very special way when combining boosts and cuts. Why? Just an example. If you boost an input signal of 1 Volt by +6 dB you have the resulting signal of 2 Volts. So a parallel equalizer adds 1 Volt to the output. If you cut -6 dB from an input signal you have the resulting signal of 0.5 Volts. Thus a parallel equalizer subtracts 0.5 Volts from the output. Now if boost and cut bands are close together a boost band always tends to win because it affects the output more than a cut band. In our example 1 V + 1 V – 0.5 V = 1.5 V (+3.5 dB of total boost). I don’t like such unpredictable behavior! The solution is to connect boost stage and cut stage in series. Check the picture. For this type of connection +6 dB boost and -6 dB cut compensate each other.

Nova-67P: the most hardcore KVR Developer Challenge (DC14) submission ever! (just kidding)

Nova-67P is a parallel parametric equalizer plugin combined with a compressor. The compressor can optionally operate in frequency dependent and split-band modes. In this case the plugin operates as a parallel dynamic equalizer.


  • 5 bands parallel equalizer with auto-gain.
  • Optional high-pass and low-pass filters.
  • Full-band frequency dependent and/or split-band compression.
  • Side-chain filtering and pre-emphasis.
  • Third-octave real-time spectrum analysis.
  • External side-chain support.
  • 64-bit internal processing.
  • Hardcore UI style.

Nova-67P is my submission to KVR Developer Challenge DC14! Okay, I didn’t have enough time to prepare truly “commercial looking” plugin but the concept is too cool to drop it away.

Nice picture and no comments

VoS + TDR = ?


What can I add for this? First, it is a great pleasure to work with these guys. Next, we have a project to be released very soon. And we’re going to release 64-bit version for it. And we’re going to release Mac version too. And… Okay, no more information for today.
