SPEAKER 1 / Phase Invert: Select Channel 1 speaker. Click the Phase Invert icon to invert the phase of channel 1.
SPEAKER 2 / Phase Invert: Select Channel 2 speaker. Click the Phase Invert icon to invert the phase of channel 2.
SWAP: SwapChannel 1 and 2 outputs.
ROTATION: Rotate the audio image. (-45 to 45 degrees).
WIDTH: Adjust the width of the signal. (0-3).
SHUFFLE: Adjust shuffle amount. (-inf to 0dB). Shuffle increases the stereo width at low frequencies which can be adjusted with the FREQUENCY knob, see below.
FREQ: Adjust frequency amount. (350-1400 Hz).
Choose a frequency between 600 and 700 Hz for classic stereo monitoring.
Higher frequencies may be better if the playback is aimed at loudspeakers often used in portable playback devices like laptops, where the stereo speakers are very close.
If you used stereo microphone techniques where the microphones are spaced apart by perhaps 20 or 30 centimetres for your source file, lower frequencies will be useful.
