You probably should not use this plugin!

This plugin applies a simple amplifier to all channels of the O3A stream. Different gains are applied for the channels introduced at each order. If you do not know what this implies, here is not the place to find out.

We wondered if we should include this plugin at all in the library, because there are rather unnatural things that can be done with it which might sound good on a particular speaker layout and decoder, but horrid on others.

This plugin is not really intended for use an artistic effect - it is here because you might have a good reason to want to mess with the order levels, probably to do with the source material you are processing. If this is the case, you probably know the gains you want already and this plugin becomes a useful tool, which is why we did include it in the end.

The plugin is available in the O3A Manipulators plugin library.


Controls: Order 0 - 3 Gains

This plugin represents gains directly as scalar coefficients, not as decibel values.

The order zero gain is applied to the first channel. The order one gain is applied to channels 2 to 4. The order two gain is applied to channels 5 to 9. The order three gain is applied to channels 10 to 16.
