I want to swap audio channels of input (left channel from microphone should be right). I have tried a few apps - LineIn, Soundflower, JACK, but they can only redirect input to output with some customisation. I want to create another input, but with replaced channels.

I have found only one app that does this - Loopback, but it costs $122.

Is there any free app that can route from input to a new input?

I want to do this for game Rocksmith, which listens only the first channel of the input, while my interface (Focusrite Solo) has guitar input on the second channel.
