Definitions

  • the set of inputs 60 may have gain applied prior to the summing. This may be important in a fixed-point DSP device, where the level of the signals inside the feedback signal path 85 needs to be controlled to prevent overflow and/or to optimize the noise performance of the reverberator. How to so achieve the scaling would be known to those in the art of signal processing.
  • a desired reverberation time at low frequency, RT low is chosen.
  • a desired reverberation time at high f equency, DecayRate iigh is also chosen.
  • the filter is then selected such that the low frequency desired reverberation time is the time taken for low frequencies of an audio signal to decay by 60dB in the reverberator and the desired high- frequency reverberation time is the time taken for high frequencies to decay by 60dB in the reverberator.
  • Typical values of RTJow can be from 200ms to 5 seconds, and even longer times are possible, while typical values of RTJiigh can be from 50ms to 100ms.
  • DelayTime is the length of the co ⁇ esponding delay, in seconds. See below for how the length of each delay line is chosen.
