Impulse Response Sample

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.

Where to get IRS?
There is an IRS Starter Pack where we gather many normal IRS from Internet for you to start with. There are also IRS made by individuals from ViPER’s Audio like zhuhang and ViPER520. They are available in this website and not included in the IRS Starter Pack.

Many users also made IRS but they are not available here at the moment. In ViPER’s Audio Official Chinese forum, there are works by many members. Some XDA members also shared their IRS in XDA. You will have to search for them.

You can also search on the Internet. There are many IR out there. They are normally in WAV extension. Make sure their duration are not too long, preferably less than 1 second for V4A and less than 5 seconds for V4W.
