In this section I aim to outline in the most basic concepts of sound production (mixing) using terminology that will be understandable to a complete newcomer.
Within the realms of sound production the term mixing is the process of balancing sounds.
When mixing all were basically doing is deciding how loud something is and where 'in the mix' the sound is to be positioned.
When mixing we control the volume, panning and EQ of each channel. A channel may be an individual sound or it may be a number of sounds grouped together.
In addition to these basic controls you may also be able to apply fx via the send/return channels. The effects send works by diverting the audio through whatever device you insert in to the send/return signal path, this is then mixed back in to the recording.
Actual design of mixers may vary but what they do remains the same and the same fundamental idea remains, basically you want to record as loud as possible (without risking distortion), as clean as possible (minimum noise), as faithful as possible (record as it was heard, no unintentional clicks/distortions etc) and hopefully create a sense of space within the mix.
there are basically 3 types of mixing with regards to spacialisation.
Mono - all sounds are placed dead center, effectivly no left/right.
Stereo - 2 channel output. Left and Right spacing.
Surround-sound - more than 2 channels (eg. left/right/center, left-front/left-rear/right-front/right-rear etc).
