What is Impulse Response Sample (IRS)?
When an IRS is loaded, V4A will process the sound to show the same exact characteristics as the loaded sample. Through Convolution, samples with effects such as equalizer, surround, reverberation, tube etc can be simulated or in short, “copied”.
However, for simulated effects such as MP3 player effects, Dolby, Beats Audio, Sony Ericsson Mega Bass etc, how close the IRS compare to real effects depends on the skills and techniques the individual IRS producer.
