harmonic and individual line plus noise (HILN)

Harmonic and Individual Line Plus Noise (HILN) is a music-optimized parametric compression technique characterized by low data rates of 4 kbit/s

to 16 kbit/s. This parametric coding extracts harmonic and dominant frequency components as well as noise components from the audio signal and then encodes them separately. HILN is used in MPEG-4 and can vary the audio frequency and playback speed independently during decoding.
