Has anyone ever heard of getting a subtle crackling noise in a final mix only when it is turned up to a louder level (Take in mind none of the tracks or plugins in the session are clipping at all, everything was gain staged and recorded at conservative volumes). Its kind of like if I play a song i mixed in my car at a conservative level everything sounds smooth but as soon as i start turning up the volume you then hear the crackling sound in the song. I know its my mixes because if I play a mainstream mix in my car i can pretty much max out the volume on those and I won't hear any crackling noise. If Anyone has heard of this or know what step I'm missing comment or give advice.
