Adaptive quantization and noise shaping distinguish lossy from lossless coders

Evidence

This is the stage that makes the difference between a lossless and a lossy coder. Again the actual signal processing can be carried out in either the time domain or the frequency domain. In both cases the process of adap­ tive quantization and noise shaping is used. — David Howard, Jamie Angus, coustics and Psychoacoustics, 2643

Categorization

• DEFINE: Names the specific mechanisms — adaptive quantization and noise shaping — that define the lossy/lossless boundary.
• XREF: Bridges to the book’s earlier discussion of psychoacoustic masking, which makes lossy coders possible.
• corroborated: 2 independent passages support this claim — David Howard, Jamie Angus, coustics and Psychoacoustics, 2643; David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 2651
