i transfer songs track by track from my Tascam 414mkII to my computer. i turn all the other tracks to 0 volume and just record a single track. i do that for each track. but, i can always sort of hear the loud parts of the other tracks in the background. when it's all together, you can't really tell. but when you isolate tracks, you can hear it. (it reminds me of when you play a record with the volume at 0.) and it's not like it's mic bleed because i recorded all the tracks seperately using headphones to monitor. is this just an unfortunate result of analog? and, if so, is there any way to fix it?
