[MIRROR] Energize II 1.40 broadcast processor Windows VST and Winamp DSP



Engergize is an excellent free broadcast processor simulator VST plugin/Winamp DSP featuring broadband AGC, stereo expander, 5-band AGC, 5-band limiter and final lookahead limiter. It can make your music sound like it's played on the radio.

The plugin does not have a graphical interface. All settings are adjusted by editing a text file. It also lacks a preemphasized clipper (the built in preemphasis is applied before the lookhead which can cause a reduction in clarity and loudness). A very basic preemphasized clipper can be manually added by chaining the effect with parametric equalizers and GClip. Note that real preemphasized clippers include distortion spectrum control which cannot be done with any of the free plugins/effects I know of.

From EnergizeIIManual.pdf (included in .zip package):
Introduction
Energize II is a 5-band audio processor suitable for Internet and low-power/budget FM broadcasting. The processor works only on stereo input with sampling frequency 44100 Hz. The processor is not optimized, which is why it consumes a lot of CPU power.

Processing overview
First in the signal chain, the audio is amplified or attenuated to the right level by what I 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 five frequency bands and the stereo image is widened in each band if chosen in EnergizeII.in. A 5-band compressor then does dynamic compression on all bands and
after that the audio in all bands is limited by different kinds of limiters suitable for each frequency range. Now each band is fed into a mixer to form two channel stereo again. This audio is then preemphasized if chosen in EnergizeII.in. Before the audio leaves Energize II, it is fed through a wide band look-ahead limiter.

Motion interpolation on a TV ad

Recently I saw a TV ad about SMS amber alerts. The ad showed a child abductor being caught because someone who got the SMS tipped the police off. The video appears to be interpolated from a low framerate like 24fps to full 60fps. How do I know? because the motion interpolater left just as much artifacts as the 120fps interpolater in my TV. I do not know how exactly this happened but the most probable reason is that they shot the commercial at 24fps then realized that 24fps looks too fake and ruins the horror effect of the ad so they interpolated it to 60fps. This relates to a disturbing trend in modern video production - 24fps. People seem to be using it (or dropping higher framerate sources to 24fps) for no real reason. All the deficiencies of old video like low dynamic range and low resolution have been addressed with improvements in video camera technology. Still, less than half of today's TV ads and prime time shows are full 60fps. We can only hope that this will be just another fad that will fade away like the overuse of primitive digital effects in the 80s.
