Thanks for that! Does anyone know if MP3s can do multi-channel too, such as on an SACD?JohnnyG said:Yup, that's mixed up all right! The sampling frequency of CD is 44.1KHz. That means that the audio waveform is sampled 44,100 times per second. Each sample is captured with 16 bit accuracy. Simple math will show you that the bit rate of CD is therefore approximately 705kb/s. That's the number to compare to an MP3 at 128kb/s.
When an MP3 is uncompressed, it's output once again matches the specs of CD.
