How loud is this?
It really depends on the preset. I wouldn't say it is blasting my ears. It is enough for me to notice it and get kind of annoyed by it.
I once thought it was my headphones because I didn't know where it came from.
I have just tested this with Virtual Audio Cable. If you set your input to run in MME mode, which is 16 bit, returned sample values on silence are usually 0, but +1 and -1 also occur quite frequently. I don't know why this is. But, given this fact, silence isn't silence but a very low level of noise. If you boost that level a lot, it will at some point become audible. Interestingly, the pattern that is returned repeats constantly.
This does not happen at all in Wasapi and Kernel Streaming modes.
Inside Stereo Tool we also add noise at -200 dB or so (as a protection mechanism; calculating with 0 values can cause the CPU usage to be 20 times higher). But there's no way you would ever see that.
Ohh!! That makes so much more sense. Thanks, so much.
I chose MME especially because WASAPI in Stereotool automatically uses Exclusive Mode (or else somehow RDS Spy doesn't work anymore???). I know this isn't very much a widely used use case but I sometimes want to run RDS Spy while there is MPX input playing into StereoTool. That's a whole other bag of worms Anywhoooo Oh my lord.
I do have some knowledge of seeing +1 and -1s audio samples while using silent Virtual Audio Cables before. I set up PortAudio to capture the audio cable and printed out the float output and saw a bunch of +1 and -1s. That confused me because I thought silent audio frames were just zero.
