Examples

channel.2, {blend: [1, -1]}

Plays one part of a multi-channel recording as mono, as a microphone facing a chosen way would hear it, before pan and output place it. channel.2 plays the second audio channel alone. The same sample plays whole wherever another assignment does not extract it. A part the recording cannot give is refused when the map loads, and a sample arriving later that cannot give it is left out of this assignment's choices, with a warning.

Accepts one of:

• omni: Every direction equally: the sum of the audio channels.
• side: A figure of eight facing left and right: the difference between them.
• depth: A figure of eight facing front and back, from a recording that carries both.
• height: A figure of eight facing up and down, from an ambisonic recording.
• left: A cardioid facing left.
• right: A cardioid facing right.
• front: A cardioid facing forward. On a stereo recording it is the same as omni, with a warning.
• back: A cardioid facing back, from a recording that carries front and back.

Example

[1, -1]

A mix of the audio channels into mono: one weight for each, where a negative weight flips the polarity of its audio channel. The weights are scaled to add up to one, so only their balance matters.
