hello guys! I've got data for mixing from a band. Some of The recording data is full of dirt. I already advice them to record again some of them. but they its just for demo, so they think it's not necessary. But, this is a big problem to me. Because its mean, Hard work over day and night before mix. Some of them were vocal, kick, snare and bass! They always muddy, vocal honky, thin and full of noises. especially when i compress them. For the bass i just used eq to get best quality even the dirt come over!because i compress and cut the unnecessary freq, finally maximazer.But its still sound fatiquing.Sometime i use multiple eq, the reason is some eq max has 10 band (wave Q10). For all of them, i found i lost my highs!caused i try to remove the noises. Can somebody help for this? Thanks a lot.
