My band recorded an album 12 years ago, and I recently came across the original reels of Ampex 456 tape. I'd like to remix the album and add more "low end" to the the final mix. Is this something I can do on my G5? on an MP? on an MBP? What software program do i need, and is there a suggested hardware set up , i.e. multiple drives, Raid, Ram , etc. ?
