recently I started a project involving drawing the images on an oscilloscope with the sound. I've read somewhere here that Bela's Line outs are DC coupled, and I gave it a try. And I liked the idea of manipulating the image with the help of sensors. But, to my disappointment, both the Line outs and Audio outs are useless for what I am trying to achieve because the noise presence in the signal makes images look bad. Is my unit faulty, or this is just a limitation of bela board?
For a comparison between RME soundcard output and Bela's output, please see attached images.
Thank you for your thoughts!
