This plugin can be effectively used to turn mono tracks into spatially-enhanced stereo tracks: it works great for clean and distorted guitars, synth instruments, piano, organ, back vocals, and other sounds. Spatifier is a “mono to stereo” spatial enhancer effect AAX, AudioUnit, and VST plugin for professional sound and music production applications. Reduced master output meter's range to 6.-48 dB, for better resolution.Added the 'Type 2' internal random number generator (PRVHASH 4.3) that produces a smoother sound.Added the 'Stereo' parameter which adjusts 'stereo width' of the effect.It is suggested that you re-evaluate the plugin due to these improvements if you didn't like the sound you got before, you may change your opinion about Spatifier now. This version features the following changes. The conversion involves reading the data samples from the wav file (in linear PCM format) and converting them to the MIDI format that the Axe uses (different formats for Axe I and Axe II).Voxengo is happy to announce the release of Spatifier v1.8, a “mono to stereo” spatial enhancer plugin for professional sound and music production applications, available in AAX, AudioUnit, VST, and VST3 plug-in formats, for macOS and Windows computers. Then take the resulting files and convert to syx using either AlbertA's utility or mine. I usually check Normalize to -0.3 dB, but it doesn't matter, as the conversion to syx will normalize it anyway. The rest of the parameters are up to you, but I'd leave Volume dB and Reversed Technique unchecked, along with Low Cut and High Cut. Set the out bit depth to 24, and you'll probably need to turn MP Processing on (try it both ways). Then give Voxengo the name of the sweep file and the name of the recorded file. All you need is mono, but if you record in stereo it doesn't matter.

Important: make the sine sweep and the recording at 48 kHz and 24 bit. Play that file through the pedal and record the response, making sure to record long enough that you have several seconds of silence at the end. You should first use Voxengo to create a sine sweep file. If you play an impulse file in winamp, at most you are going to hear a 'click' sound, which is the sound of an impulse. When you use a sweep instead of an impulse, you need to go through a deconvolution step to create the actual impulse response, which is what Voxengo Deconvolver does for you. If you put an impulse into a device and record the output, you have an impulse response.

Actually, an impulse response is an audio file.
