I've been experimenting with lossy codecs on my laptop. I've been comparing different file formats to see if I can tell the difference in a blind test. I've been comparing:
- WAV Files
- FLAC Files
- AAC Files (using Nero's new encoder)
- MP3 Files (using the latest stable Lame encoder)
I find MP3 files the easiest to spot and some of the lower bit rate AAC files (ie less than 320kbps). It gets a lot harder to spot AAC files encoded up to 465kbps and well, I don't think it should be possible to spot FLAC files.
So here's a thought - if you were handed an audioCD with say 3 differentpieces of musicon it, with each having been originally encodedin say half a dozen of the highest qualitylossless and lossy formats (to make 18 tracks in all), would you be able to spot the "unmolested" tracks?
Obviously the tracks would have to in a random order and the test would have to be done on Hi-Fi equipment - you can work out which ones were MP3s and AAC files with appropriate software on a PC.
