MPEG-1 Audio Compression - Step 2 •By applying a bank of filters, separate the signal into frequency bands. •The samples are divided into frequency bands for psychoacoustical analysis. Each filter removes all frequencies except for those in its designated band. •The use of filter banks is called subband coding. In MPEG-1, the number of filters is 32.
