Two new plugins: Comb Filter and Volume Halver

I made two tiny plugins in the meantime and want to share them with everybody.

Comb Filter

Among hundreds of effect racks, mastering suites and filter banks sometimes it’s hard to find exactly what you are looking for. That thing was comb filter, as simple as possible. What it does is to filter out even or odd harmonics and boost the others – perfect for shaping the noise of percussion, in particular.

Take a look at frequency response from Wikipedia:

Alpha on the graph is represented by “Mix” knob, while “2pi” is your frequency.

Comb Filter

Comb filters are also elements of phasers and flangers, so you may want to use them that way.

Features

  • Positive or negative ratio
  • Minimal CPU usage
  • High precision control

Volume Halver

Plugin designed to reduce track volume before mastering without loss of precision.

Halving the volume may sound like trivial operation, but there’s more in it. If you try to lower the volume directly from your DAW, multiplying by real number may result in rounding error. Volume halver fixes that, as it multiplies the signal exactly by half, so no rounding is present. This way the only precision you may ever loose is the least sgnificant bit – but that’s inherent disadvantage of any computer system and not the tools you use.

It doesn’t even have GUI – just drop one on two on your track before mastering, so it does not clip.
