I am listening to Spotify/MP3 on my laptop with external sound card and headphones.
Is there something like dedicated track that will help me evaluate the level of internal noise of my system? I found a track called digital silence but the system probably didn't output anything at all because I could not hear any noise, no matter the volume, but with some silence inside other tracks I was able to hear the noise difference between the laptop's internal sound card and the external one.
There is this song on Spotify named Digital Silence but when I play it on max volume from my laptop (over headphones) I can't hear ANYTHING. While in case of other songs on max volume I think I can hear noise in them that gets improved when I use external DAC. My assumption is that the laptop will not output any signal at all in case of the Digital Silence track.
