well hello, complex like talkers. excuse my absence, i couldn't remember my username or password for a while. i don't really have much to say today aside from "hello" so please excuse my abuse of this forum, if indeed i have commited said offence. digital cd quality sound has a sampling rate/frequency of 44.1 kHz and 16bit depth meaning each individual cycle of sound (1 every 1/44100th of a second) can represent any 1 of 2 to the exponent 16 (approx. 65000) sound amplitudes. dvd sound is 88.2 kHz and 32 bit. mp3s are a compressed file format. an mp3 is created by taking uncompressed digital audio data, and removing all frequencies imperceivable by the average human ear, as well as all frequencies 'masked' by an overlapping of two other frequencies (a violin and piano, for example).
godspeed.
