Audio Processing means changing the characteristics of an audio signal in some way. Processing can be used to enhance audio, fix problems, separate sources, create new sounds, as well as to compress, store and transmit data.

Chain of effects and their order

There are many different audio effects that can be applied alone or chained in sequences of effects. To preserve the clarity of the tone when chaining effects it is most common to put:

1. at the start of the chain: compression, wah and overdrive;
2. in the middle: modulation (chorus, flanger, phase shifter);
3. at the end: time-based units (delay/echo, reverb);
4. additionally, and because when using many effects unwanted noise and hum can be introduced into the sound, some performers use a noise gate pedal at the end of a chain to reduce unwanted noise and hum introduced by overdrive units or vintage gear.

Listen them

• Dont forget it all starts on the tone of your guitar:
  Single coil pickups are more bright/treble (good for example for country). This are usually found on stratocaster and telecaster models (Fender);
  Humbucker pickups are more fat mid freq (good for rock/distorcion). This are usually found on Les Paul (Gibson) models.

• Compressor: low sounds sound louder and louder sounds sound lower. You can still feel changes in dynamic (what is a good thing, since you want to impress feeling) but the sound wont clip when it gets too loud.

• Delay:

• Distortion, Overdrive and Fuzz (they are very similar)Overdrive in general "make fat" the tone, and preserve most of the original attack of the guitar. Depending on amp and setting, do something like a more cranked tone of same kind. This is especially true when you turn down volume, one of more important things to to to judje anything on electrig guitar stuff (amps, pedals, pickups).
  Distortion are usually harder in attack, if the pedal is good is anyway dynamic and make the original tone understandable, but even of low distortion values the tone is different and neither at low volume setting became clear and soft as the overdrive.
  Fuzz has a deep effect of the waveform, it change totally attack of the instrument. Is very dirty, and even if clean up lowering volume (any good pedal should) the break up is quite violent, so depending of style doesn't fit all usage, but is quite effective and has plenty of harmonics and sustain. The change and destroying of attack make the fuzz difficult to use for any percussive use, like funky but even metal use."

Compression

Audio compression is a method of reducing the dynamic range of a signal. All signal levels above the specified threshold are reduced by the specified ratio.

The example below shows how a signal level is reduced by 2:1 (the output level above the threshold is halved) and 10:1 (severe compression).
