IR-A-Live is a brand new concept brought to you straight from the AcmeBarGig & eXe Consulting Research and Development team which allows live convolution of stereo inputs.

A Little Confused?

With such a unique concept there’s bound to be a little confusion surrounding the intended use of this plugin, so we’ll try and lay it out in the easiest terms possible

IR-A-Live will convolve a stereo signal from a track’s Input 1/2 with 2 stereo Impulse Response signals from Input 3/4 and Input 5/6 of the same track.

This basically means that Input 1/2 contains the stereo signal you want to be processed, Input 3/4 contains the first stereo signal to be used as an Impulse and Input 5/6 contains the second stereo signal to be used as an Impulse

This allows you to add Impulse Response convolution to a source signal (Input 1/2) based on the input from two stereo signals in your VST host, provided it is capable of re-routing signals between tracks (most commercial DAWs e.g. REAPER). Here’s the magic: these input signals could be any audio you want them to be! Standard Impulse Response files, full songs, essentially IR-A-Live will create an Impulse Response out of each of the input files and convolve your source signal using these. What’s more if your sound card has at least 6 input channels, you could even plug in an instrument and IR-A-Live can convolve this instrument’s input signal in real time.

An Example

Let’s say you’ve got a pretty progressive piece that goes from a huge heavy riff that starts at 1:10 and changes at 4:13 to a softer, mellower lead tone. Let’s say that for the heavy riff we want to have a different cabinet. We simply place our cabinet Impulse File at 1:10 on our Impulse Track. Let’s also say that for the mellower tone we want to sound like we’re in a different studio. We place this new Impulse File at 4:13. The source track is then convolved using the mixture of Impulse Files.

Of course, this is a very basic example, this is a brand new concept that we believe can yield some awesome results, so get creative!

Erm, great, so how do I use it?

First, you want to create the stereo track you’ll be processing. It’s default audio inputs should be set to 1/2. In this example we’ll call it ‘Track 1′, because we’re so friggin’ original. Add an instance of IR-A-Live to the VST Effects of this track.

Create a new stereo track for each signal you would like to use as an Impulse Response signal, we’ll call these tracks ‘IR1′ and ‘IR2′.

Add the files you would like to be used as your IR signals to these tracks and make sure that the files sit where you want them to sit on the timeline. You can always set up a loop or duplicate/copy and paste the files.

Take a look now and you have your source track ready for recording (or with a part already recorded if you’re dealing with a previous recording) and two Impulse Response tracks, hopefully with the files you’d like to use as Impulses sitting on their necessary places in the timeline.

Slow down though cowboy, because this is the important part, you’ll have to ‘Route’ the I/O of the tracks so the Impulse Response tracks point to Track 1′s Input 3/4 and Input 5/6 channels. This routing process will likely be slightly different for each DAW but the routing configuration will be the same. For our IR1 track, we send IR1′s Output 1/2 to Track 1′s Input 3/4. For IR2, we send IR2′s Output 1/2 to Track 1′s Input 5/6, you might have to disable the ‘Master/Parent Send’ (this is what REAPER calls it, other DAWs might have a different name for this send) of the IR tracks depending on your DAW. If you are confused as to how to route tracks, please consult the manual of your DAW.

Now you have the tracks added, the files added to the Impulse tracks and the routing set up so we’re sending our Impulse Track’s Output to our Source Track’s Input 3/4 or Input 5/6 channels, you can start playing with IR-A-Live! Make sure you arm the source track for recording and hit Play in your DAW, if you have configured everything correctly the signal of the IT track(s) will be convolved with the audio of the source track.

System Requirements

These requirements are what we've found to be a 'usable' environment for our plugins. By 'usable' we mean they run fine with low latency and acceptable CPU usage. Anything higher than these requirements will hopefully have you running things smoother than a sanded-down P. Diddy. Covered in silk. Or something …
