As you note, this is really a question about XAudio2's implementation rather than a question about DirectX Tool Kit for Audio.
Looking at the source for XAudio 2.7 (the last version to support Windows 7), the reverb supports:
It uses the Princeton Digital Reverb 2004 algorithm.
There are a number of parameters for left vs. right channels. In the mono case, the right channel information is unused as noted in the code comments in xaudio2fx.h
.
For mono-processing, the standard approach is to replicate it to the 5 left/right/center channels (no LFE). For stereo-processing, all left channel information goes to the left surround speakers, right to right, and center is a mix.
In the standard X3DAudio set, you drive LFE from
X3DAUDIO_CALCULATE_REDIRECT_TO_LFE
. See XAudio2Sound3D
Thank you very much!
I don't know where is the right place to ask this question, so I put it here, sorry.
According to XAudio2's document, the reverb support mono/stereo in 5.1 out.
If I create the reverb with mono input and 5.1 output, will there any difference among the 6 output channels, or they'll just be the same reverb effect?
Thanks
