V2.1

2     Functions

  1. Receives Spherical Harmonic Decomposition Coefficients, Transform Speech, Audio Scene Geometry, and Source Model KB info.
  2. Eliminates background noise and reverberation which reduce the audio quality, acting as a Passthrough AIM if environmental conditions do not substantially add ambient noise to the desired speech.
  3. Produces Denoised Transform Speech
