Impulse Response Processor

VST Plug-In Technology by Steinberg Media technologies
This plugin is FREEWARE. Use at you own risk.
No warranty at all.
The software is provided "as-is," without any express or implied warranty.
In no event shall the author be held liable for any damages arising from the
use of the software.
This is a reverb device that works with "impulse-responses". Impulse-
responses are generated by recording short, broadband signals and their
corresponding room-reflections.
Due to technical reasons the plugIn works with a fixed latency of 8960
samples that is possibly compensated by the VST-host. SIR is a stereo
plugin. To take full advantage of stereo impulses for mono signals, you can
first convert the track to stereo.
__________ Help __________
- Open File
loading impulse-response wav ( Windows PCM ) file
- Predelay
the delay between signal and the first reflections
- Attack / Time
these parameters are to adjust the intial of the impulse-response,
maybe usefull to change early reflections
- Length
reducing the length of impulse-response
- Stretch
up & downsampling
- Stereo IN
stereo width of input signal to analyze
- Stereo IR
stereo width of impulse response
- FFT EQ
to adjust the frequency spectrum of the impulse-response
add points with the left mouse button, delete points with the right mouse
button.
- Auto Gain
automatic volume compensation
- Dynamic CPU Consumption
use only the CPU power that is needed to get the result
