This is some of the very basic things I have learned on my recent endeavor into the field
and art of sound recording and mixing. It is admittedly elementary, but I hope it will offer
some basic insights into mastering tracks and stimulate further individual exploration and
experimentation in the field.


The art of transferring sound to CD is an art- form and should be left to the pros… but
why let them have all the fun?! Besides, you may be looking to make a demo with your
band, perhaps you have a basic recording program on your computer and a mic or two.
So hopefully this will help, once you get the track laid down, how exactly to tailor it to
your liking.

*Present Chart on


   -   The most common form of signal processing.

   -   “Allows tonal control over harmonic and or timbral content of recorded sound.”

   -   Since we‟re talking budget, EQ will most likely play a critical role in helping
       clean up the sound.

   -   Eliminate unwanted overtones that may distort certain notes due to the room

Compression (Wave Hammer)

   -   Basically, the Compressions gives all the recorded audio a voice – sounds that
       would normally be less pronounced or buried are brought up in the mix.

   -   Many times, the goal is to make the recording “hot”, or to raise the volume levels
       as high as possible without distorting the sound. You‟ll find this predominantly in
       popular music, such as Hip Hop or Rock.

   -   A good ratio would be 4:1 to start out on

Limiting/Expansion (Graphic Dynamics)

   -   For limiting, if the compression ratio is large enough, the compressor will become
       a limiter.

   -   This is handy if there are signal peaks that exceed a certain level

   -   Expansion is, of course, the opposite of Limiting. Basically, the goal here is to
       increase or decrease the gain in order to achieve a certain even dynamic range
       throughout the piece


   -   This is also an expansion device.

   -   Noise-Gate allows signals above a selected threshold to pass through without
       effecting the overall dynamics or sound.

   -   Proves useful in eliminating, say, monitor buzz, or your girlfriend/boyfriend
       doing dishes in the background.

Time-Based Effects

   -   These effects often add to the depth of a signal or modify the recorded sound,
       which may or may not be desirable

   -   All based on Delay or regenerated echo loops – hooray for algorithms!

   -   Reverb = extremely important to the enhancement of music = dimensional space
       and warmth

Other Considerations

   -   Monitoring = Though headphones are good in the sense that they remove the
       listener from the “room‟s acoustic environment” and allow the listener to
       determine specific spatial positioning within the recording – they don‟t give a true
       representation of how sounds will behave through loud speakers. Also,
       headphones emphasize low frequencies, which may not translate well to loud

   -   Overdub = For cleaner, more articulate sound, one could attempt to record parts
       separately if recording an ensemble… and or instrument, then vocals, etc.

   -   Optimum levels when mixing sounds

   -   Not all listed suggestions will be right for you… “Artistic Considerations”
