Am I losing much sound quality when going mp3 -> flac do you think or is the quality lost negligible? I know obviously the sound won’t increase but will it decrease? Specifically a 256Kbp/s VBR mp3 track?
the quality won’t decrease because flac is a lossless codec, it will be the same as the source, no audio loss.
but seriously, why would you want to convert mp3 (or any other lossy format) to flac? that is kinda pointless anyway…
To burn on CD and store in FLAC database to use later for DJing etc.
