Perceptual audio coding

Perceptual audio coding evolved largely independently of audio modeling in computer music, up until perhaps when HILN (advanced sinusoidal modeling) was introduced into MPEG-4 [217]. Below is a sparse collection of salient milestones in the history of modern perceptual audio coding that came to the author's attention over the years:

• Princen-Bradley filter bank (1986) [214]
• Karlheinz Brandenburg thesis (1989) [24]
• Auditory masking usage [200]
• Dolby AC2 [53]
• Musicam
• ASPEC
• MPEG-I,II,IV (including S+N+T ``parametric sounds'') [16,273]
