Audio DSP Channel output question
« on: April 11, 2010, 09:09:51 am »

Hello:  Is it my imagination, or did it used to be that when "2 channels (stereo)" was selected in the output format pulldown menu, mono audio was routed to both channels?  I found some time ago that if I set output to stereo, my 22.5Khz sampled mono audio files would play back in WASAPI mode.  I noticed recently that these files were playing in the left channel only.  I could swear that they used to play from both channels.   What say you?

Mono should be mixed to stereo when stereo output is selected in DSP Studio > Output Format.

We'll test on our end and see if we can reproduce it.

Thanks.
