Delay of Binaural Rendering

This issue is to track discussion on the delay in binaural rendering.

Points that require verification/discussion are:

• Should binaural filtering delay / HRTF "latency" be taken into consideration for codec/renderer delay compensation?
  • How should the rounding/conversion of delay be performed to sample domain (see NS2SA() vs roundf() discussion here)
• Is the LFE signal correctly delay aligned to binaural output in the various renderers used for multichannel rendering?
  • Parametric renderer (McMASA)
  • Fastconv renderer (ParamMC)
  • Crend renderer (MCT)
  • TD Object renderer (MCT for planar layouts with headrotation, see #59 (closed) )
