ABSTRACT:
Frequency components are broken into a first signal made up of a plurality of tonal components and a second signal made up of other components. The number of the frequency components making up the tonal components is variable. Tonal signals may be encoded efficiently depending on the manner of distribution of their spectral energy to assure more efficient encoding on the whole. If the signals compression coded in this manner are recorded on a recording medium, the recording capacity may be employed effectively. Also, high-quality acoustic signals may be obtained on decoding signals reproduced from the recording medium.
