12.33 UV22HR Dithering 369
For testing signal processing methods.
For educational purposes.
The TestGenerator is based on a waveform generator which can generate a number of basic
waveforms such as sine and saw as well as various types of noise. Furthermore, you can set
the frequency and amplitude of the generated signal. As soon as you add the TestGenerator
as an effect on an audio track and activate it, a signal is generated. You can then activate
recording as usual to record an Audio File according to the signal specifications:
Waveforms and noise section
Allows you to set the basis for the signal generated by the waveform generator. You can
select between four basic waveforms (sine, triangle, square, and sawtooth) and three types
of noise (white, pink, and brownian).
Frequency section
Allows you to set the frequency of the generated signal. You can select one of the preset
values (100, 440, 1000, or 10000Hz), or use the slider to set a value between 1Hz and
20000Hz.
Gain section
Allows you to set the amplitude of the signal. The higher the value (up to 0dB), the stronger
the signal. You can select one of the preset values (e.g. -20dB), or use the slider to set a
value between -81 and 0dB.

12.33 UV22HR Dithering
The UV22HR is a high quality dithering plug-in, based on an advanced algorithm developed
by Apogee. It allows extended information (from 32 bit floating point or 24 bit integer audio)
to be encoded into a standard medium such as CD, MP3 or AAC without loss of sonic
integrity. No pre-auditions or settings are necessary and audio detail is retained up to 30dB
into the noise floor.
For an introduction to the concept of dithering, see Dithering.
