ABSTRACT:
An apparatus for compressing a digital signal in which a block of a spectral components in the frequency domain is divided in frequency into at least two sub blocks. The peak value for each sub block is determined, and the difference between the peak values is determined. Block floating is applied to each sub block individually when the difference between the peak values is above a fixed value. This prevents quantizing noise from being heard when the input signal is highly tonal.
