Spectral Panner is an audio plugin that does stereo frequency-based panning. It pans each frequency bin, providing more control over the stereo image than regular stereo panning at the cost of latency (which is required for a high-resolution FFT). Because of the high latency, it is not adequate for real-time processing but works well in post-processing.
There are two panning modes:
- Stereo Balance, which reduces the volume of the left channel when panning right and the other way around. In this mode, there is a slider for side gain compensation because the signal energy will naturally be reduced when panned.
- Stereo Pan, which mixes the two channels, moving information from one channel to the other.
