Que?

A comb filter puts mixes the signal with a slightly delayed version, so that phase cancellation occurs. It's the same technique as a flanger, but the flanger adds the factor of the comb filter opening up and closing down with an LFO.

A vocoder is something entirely different. It analyses a "modulator" signal in the following way: the signal is divided up into a defined number of bands (i.e. 16 or 32 or w/e), and for each band the volume envelope is passed on to a "carrier" signal, divided into an equal amount of bands. The modulator is typically a vocal, and the carrier a synth, though this is not necessary. The signal you ultimately hear is the carrier, but with some of the frequency responses of the modulator applied to it as described.

Wrong. A comb filter, aka formant filter (just more flexible), is a huge bank of bandpass filters. The reason it is called a comb filter is because setting these bandpass regions, on a spectral display, it will look like you ran a comb through it. What you were describing sounds more like a phaser.

[EDIT:] Wikipedia gives almost the exact same thing as you however, the difference being is they dont go into further depth of how one really interfaces in the music world. I suppose at the very basic level, that is what happens though.

A comb filter is not a bank of bandpass filters, it is a bank of bandreject/notch filters. This same effect is acheived by a flanger, which is why they are synonyms.

It is also not a formant filter, which is really just an EQ that is set to emulate the resonance curves of formants, or the vowel sounds of the human mouth. (Fun Fact: Your mouth is one big, sometimes stinky, EQ. Have some Altoids.)

A phaser is in fact also a comb filter. The difference between a phaser and a flanger being that you can control each "tine" separately, and can create irregularly spaced "tines" as a result.

OMGWTFBBQ?!

Thoughtlessjex, please could you break that down a bit more?

I've always known what the effects SOUND like, but never known what they are ACTUALLY doing?

If you could explain it a bit more, then maybe we could place it in the stickies too, I feel if people know what they are actually doing to their sound, they may be able to control them better also?

Cheers,

And good advice coming from everyone! Even if all is not 100% correct, its all part of learning!

Technically, all this stuff is in the stickies. It just takes some digging to find.

The Tutorial Master List thread has a link [http://www.theprojectstudiohandbook.com/directory.htm]here[/URL], which eventually led me to this article on phasers. It also touches on the relationship between phasers and flangers. That thread and the directory that it links to are treasure troves of information. It just takes some time reading through them to figure out what all your kit does.
