I recently recorded something using Windows WASAPI and loopback by playing it in another program. I get this funny alternating pattern and I’m wondering if it’s the hardware. I also tried the exact same thing on another computer and got a quieter, different waveform. It looks like overall there are still quiet and loud spots, but they’re not as pronounced.
First of all, is computer 2 the best recording of these? Is computer 1 somehow clipping this? Next, why the different volumes; is this a function of the hardware or is there some volume that can be adjusted? (The volume of the program playing the audio was set to max.) I read a little about WASAPI, and I’m guessing it’s “connected” more with the program playing the audio (which is why the microphone isn’t available in Audacity)? Finally, to fix the audio, I suppose I would just normalize by section?
Mostly I’m just curious as to why I’d get these results. Thanks for your analysis.
