Flanger vs. phaser

Submitted by mic on Thu, 01/02/2020 - 15:09

I read a few articles about flangers vs. phase shifters and watched some videos. I found them unsatisfactory. It is hard to tell the difference. Many videos talk about more or less "whooshing", "bright", and "pronounced", but all of that means little to me and depends on the settings. Also, videos contradict each other.

Having designed flangers and phasers, I would say:

Multi threshold compressors

Submitted by mic on Mon, 11/26/2018 - 12:47

I am testing my compressors. I start with a simple frequency of 400 Hz over the sampling rate 8 kHz. I apply a volume envelope over this frequency. The envelope is simple.

  • The volume is zero over the first 400 samples (about 50 milliseconds).
  • It increases gradually (a straight-line increase) to 0.9 over the next 80 samples (10 ms).
  • It then decreases gradually to 0.4 over the next 1600 samples (200 ms).
  • It is sustained at 0.4 over the next 3200 samples (400 ms).
  • It decreases to zero over the next 4800 samples (600 ms).

Orinj version 4 beta

Submitted by mic on Wed, 09/26/2018 - 13:34

We are releasing version 4 of Orinj.

Beta release of Orinj

This is a beta release.

Beta means that this release has not been fully tested. We do not guarantee that it is stable. Use it if you are adventurous and want to experiment with the new features of Orinj.

Equalizing vocals

Submitted by mic on Wed, 08/22/2018 - 21:27

When equalizing vocals, much of the work involves removing offending frequencies. We do so by cutting out a narrow band of frequencies.

Typical recommendations are:

  • If there is too much low frequency rumble, cut down on frequencies below 80 Hz.
  • If the vocals are booming, look for an equalizer that can put a magnitude reducing notch with a middle frequency somewhere between 100 Hz and 300 Hz, dipping down to, say, -30 dB, and a width at -3 dB of probably about 100 Hz. You would have to experiment by moving the notch up and down the interval between 100 Hz and 300 Hz to find the offending frequency band.
