I am starting to get some mobile gigs (events, parties & weddings) so I have been working on my playlist. Most of the music I download from Amazon, Beatport & iTunes is 256kbps to 320kbps MP3 but a lot of my older music that I burned from cd's are only 128kbps - 192kbps since that was the best you could burn a mp3 at the time (5+ years ago). I did keep those cd's so I am going to burn them again so I can get better quality. I have read A LOT of articles and blogs saying the WAV and Apple Lossless is the best but takes a lot of storage. I did burn one track as an Apple Lossless and could not tell a diff between it and a 128kbps file through my headphones but I am sure it would be diff over a PA. Should I burn these older tracks in 320kbps, WAV or Apple lossless? I know WAV & Apple Lossless is superior but should I stay consistent with my tracks and have them all 320kbps MP3?
BTW Most of these songs are from the 70's, 80's, 90's and early 2000's, top40, pop, hip/hop, r&b, and rock.
Thank you in advance for your replies!
