Provides support for level processing of an audio stream. Supports VU-meter, spectral analysis, audio amplifier, dynamic range compression, event triggers and delay correction.
Overview
The Audio Level filter is used to accomplish various manipulation techniques on an audio stream. It accepts audio data in PCM or IEEE_FLOAT formats, transforms it into its audio data stream for further processing and/or rendering. The Audio Level filter is able to setup transform functions for each audio channel.
Features
- VU meter.
- Spectral analysis (11 octaves with 1 -:- 6 bands per octave, multiple window functions and different Fourier window lengths).
- Audio amplifier.
- Dynamic range compression (auto gain).
- Audio trigger.
- Delay correction.
Specifications and description of user interfaces can be found in the .idl file in the \Idl folder of the filter installation directory.
Supported Standards
- The E.B.U. standart peak-programme meter for the control of international transmissions
