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
