Fact 2. Storage is so affordable these days, there is no longer an argument for saving a lower quality file.
Fact 3. An MP3 320 is lossy and compressed. A WAV is lossless and uncompressed.
Fact 4. MP3 and other lossy formats exploit general human hearing to reduce file size. That was the only reason for it to be used, thus causing quality loss. Perceptable hearing depends on the user and the amount of compression used.
Fact 5. A WAV file can contain LPCM encoded data, ADPCM encoded data and even MP3 encoded data.
Fact 6. An MP3 will never sound better than a Wav, no matter what kbps it’s at as it is all still lossy.
Fact 7.John Rofrano has quoted that WAVs will always sound better than MP3 so stick to the Wavs.
Fact 9. Using mid side processing on a MP3 is pointless when working with sides because the information in the sides has been degraded to reduce file size, taking out crucial frequencies, which is replaced by digital noise. WAV lossless will benefit from mid sides processing espicially when being mastered.
Fact 10. If a MP3 is played out in a club, the stereo information is brought into the dual mono signal, and the digital noise is still there. If a WAV is played, the stereo information is brought into the mix as lossless quality.
Fact 11. If a DJ set is full of MP3s, and then recorded, and then compressed again for people at home to listen to, you get even worse information loss and degraded music because it’s been compressed numerous times.
Fact 12. If a DJ set is full of WAVs, and then recorded, and then compressed to a MP3 320 format, the audio for the listener is better than fact 11.
Fact 13. MP3s have a higher distortion, with a flat 2 dimensional sound and WAVs have a higher quality coding.
Fact 14. Higher resolution, uncompressed sounds is what you get on a CD. Evidence here. Uncompressed audio is better. Every CD has the full information, so there is no point in putting an MP3 on a CD when you’re playing audio not data. When you buy albums on CD, you are buying the highest quality mastered music.
