Energize II

5-band broadcast processor

A 5-band broadcast processor intended for internet and low power FM broadcasting. First in the signal chain, the audio is amplified or attenuated to the right level by what they call the AGC. After that, if chosen in EnergizeII.in, the audio is fed through a steep 15 kHz low pass filter. Then the audio is split up into 5 frequency bands and stereo widening is done on the bands if chosen in EnergizeII.in. A 5 band compressor then does dynamic compression on all bands and after that all bands are limited by different kinds of limiters suitable for each frequency range. Finally each band is fed into a mixer to form two channel stereo again. This audio is then pre-emphasized if chosen in EnergizeII.in. Before the audio leaves Energize II, it is fed through a wide band look-ahead limiter.
