Very true, and further, there’s really no need for lossy formats at all anymore. They were invented strictly to reduce file size and allow for the digitization of music collections - they were not invented to improve live performance or sound quality. Now that storage is so cheap and we have controllers like the Prime 4 available to us, with native lossless support, I think DJs should be taking advantage of the highest fidelity files possible. The world’s ears will thank you (especially at clubs… maybe not so much at less designed venues).
On that note, isn’t it funny that in the video world, we are constantly seeking better and better video quality… whether that’s through 8K movies or 4K HDR video gaming… yet in audio, specifically DJing, we are OK with having lower audio quality as we progress in technology. It seems backwards to me, but I think it’s due to so many years of having mp3’s that we’ve just gotten accustomed to it. Hopefully that trend reverses itself in the future.
