I tried the -70dB track on topping DX7s, and im getting a lot of background "hissing" noise. this hissing noise is louder than the music itself.
the second interesting part is that if i upsample this track with my media player, the background hiss will reduce but the track will get more distorted. on 32 bit upsample, the hiss almost completely dissapear but the sound is severely distorted.
im really curious if this hissing noise is part of the original track, or is it residual of the signal processing? much appreciate feedback from others on this.
