I don't have the hardware required to listen to
that, but a
friend of mine does. The disc has two songs on it, a jazz trio
(piano, upright bass & drums) and a string quartet. Each song
was simultaneously recorded at three different PCM resolutions:
16-bit/44.1kHz, 24-bit/96kHz, and 24-bit/192kHz. Subsequent to
that they recoded the recordings into MP3, WMA, and AAC. My
friend and I listened to the recordings in order from expected
worst sound to expected best sound. MP3 sounded just OK. WMA
was slightly better to us, and AAC was again noticeably better.
The jump from AAC to 16-bit/44.1kHz was dramatic, as was the next
jump to 24-bit/96kHz. Going up to 24-bit/192kHz was also better
yet, but not as dramatic. After that we went back and listened
to MP3 again and it sounded as if it was being played through a
distortion pedal for an electric guitar by comparison.
you did this all double blind, right? if not, then why bother?
