Very important clarification. So may I conclude the folliwing ?
- if the sound source is mono (e.g. kick drum bass, ...), then I should use the M-S IRs
- if the sound source is already stereo, then I should use the quad IRs
What's the difference in terms of sound between using the M-to-S file with Direction Mixer as M-S decoder w.r.t. to use
the corresponding quad (True Stereo) file ? Are they targeting different use cases ?
