Mixing Tips: Know Your Signal Flow in SONAR

Signal Flow is an important concept to understand, and it may be easier to think about when presented with a diagram of how audio is passes through SONAR.

Inputs and Outputs – Easier than you think!

The first concept to understand is the relationship between Inputs and Outputs. There isn’t anything complex about the subject unless you over-think it.  It is the underlying theme to just about anything within your Digital Audio Workstation. Always remember the following:

  • Outputs: Always feed Inputs
  • Inputs: Always fed by Outputs

Sometimes Outputs can be named “Outs or Sends” and sometimes Inputs are labelled “Ins or Returns.” If you’re a guitar player then you can associate this concept with the FX Loop that exists on the back of your amp. You use this to Send audio to your effects pedals and then back to your Amp’s Return.

First, let’s start where audio starts. Typically it begins with an instrument or audio file:

You know you want it…there’s something irresistible about a greasy wah effect

by Craig Anderton

Some people think all you really need for a wah sound is to set a parametric EQ to bandpass with a fairly high Q, and sweep it back and forth. However, a vintage wah’s bandpass filter has a skirt that rejects high and low frequencies, which doesn’t happen with a parametric EQ’s bandpass response.

I came up with a technique that does the vintage wah effect quite well by copying a guitar track and flipping it 180 degrees out of phase so the signal canceled. Then, I’d set one track’s parametric to bandpass with a fairly high Q and sweep it. Because the only difference between the two channels was the bandpass peak, that’s all you heard—the highs and lows canceled out.

The VC-64 is ideal for this application, because it has two parallel paths and you can throw one of them 180 degrees out of phase. However, it’s a very Continue reading Anatomy of an FX Chain: CA Vintage Wah (Free Download)
