Imaging

Mono

Mono (short for monophonic) means one channel of audio.

  • when recording a microphone into an audio interface using one microphone and one channel, that is the definition of mono

When we have a mono signal in our DAW, eventually it gets sent to a stereo bus. It’s technically still mono information, but that same mono signal is now sent both to L and R. This is what creates a centre image.

  • Mono information in a stereo environment equals centre information. As our ears hear the same thing from either side at the same volume and at the same time, our brains localise that as centre

Stereo

Stereo (short for stereophonic) means more than one channel of audio.

  • precisely, it is the reproduction of sound using 2+ independent audio channels

Stereo Image

Stereo width is achieved when what comes out of the left is different to that of the right.

  • ex. when tracking guitars, record the same part twice and pan them left and right respectively. This works because they are two different pieces of audio, giving off a sensation of width.

A wide stereo image is when a sound seems to be coming from multiple angles (like a wall of sound)

  • the more different the sound out of L is from R, the wider the stereo image. The more similar L is to R, the narrower the image.
