Lossy encoding can be viewed as a low-bit-depth quantization of a signal. The precision of this quantization depends on the selected bitrate, while quantization noise (a compression error: the difference between the original and the decoded signal) is spectrally shaped to be minimally audible — this is achieved by a psychoacoustic model.

The amplitude of quantization noise depends on the chosen bitrate and signal complexity. Slowly-changing tonal signals are easy to approximate, while random noises are hard (see the examples below). The amplitude of compression noise is often proportional to the signal level, much like with a 32-bit floating-point sample format. The noise of a 32-bit float format is always 150 dB lower than the signal level, while the noise of mp3 or AAC compression is usually only 15–30 dB below the signal level.

When quantization noise is added to the waveform, it can change the peaks levels. Izotope all products keygen mac download. If the waveform has been brickwall-limited to a certain level, chances are that 50% of waveform peaks will rise in level.
