(8.D.2.2) ScalerNFract32
Overview
Linear scaler Fract32 with independent gains
Discussion
Multichannel scaler, where each input channel has its own individual gain value. The gain parameter consists of an array of gains, one per input/output channel.
Note that this module does not do smoothing. Changes to gains may introduce audible clicks. ScalerNSmoothedFract32 module is a smoothed version of this module.
Type Definition
