Voxengo Stereo Touch User Guide
Introduction
This professional audio plug-in implements a classic technique of transforming a
monophonic track into spacious stereophonic track by means of mid/side coding
technique.
Stereo Touch is most effective on monophonic sounds without overly sharp
transients: it works great for both acoustic and electric/overdriven guitars, synthetic
pad sounds and even vocals. By means of this plug-in you can easily get spacious and
even “surround” sounding tracks, without utilizing a double-tracked recording
technique.
Basically, the plug-in takes a mono input signal and generates a stereo output signal.
This plug-in can also work with multi-channel input signal, but in this case all
channels get processed independently of each other like they are separate mono input
signals, and then all resulting stereo streams get mixed together to produce a single
stereo output signal.
Features
Two delay lines
Built-in low-pass and high-pass filters
64-bit floating point processing
Preset manager
Undo/redo history
A/B comparisons
Contextual hint messages
Zero processing latency
Compatibility
This audio plug-in can be loaded into any audio host application that conforms to the
AAX, AudioUnit, VST or VST3 plug-in specification.
This plug-in is compatible with Windows (32- and 64-bit Windows XP, Vista, 7, 8, 10
and later versions, if not announced otherwise) and macOS (10.8 and later versions,
if not announced otherwise, 64-bit Intel processor-based) computers (2.5 GHz dualcore or faster processor with at least 4 GB of system RAM required). A separate
binary distribution file is available for each target computer platform and audio plugin specification.

User Interface Elements
Note: Most interface elements (buttons, labels) located on the top of the user
interface and on the bottom are standard among all Voxengo plug-ins and do not
require much learning effort. For an in-depth description of these and other
standard user interface elements and features please refer to the “Voxengo Primary
User Guide”. Learned once it will allow you to feel comfortable with all pro audio
plug-ins from Voxengo.
Side Channel Delays
This group of knobs controls the characteristics of the produced side channel
information that is used to add the “stereo touch” to the input mono signal.
Side channel information is produced by delaying the input signal and using delayed
signal as a side channel directly (two separate delay lines are available for this
purpose). An optional filtering is then applied to the side channel, before it is used
for mid/side decoding.
The “Delay 1” parameter adjusts first delay line’s time.
The “Delay 1 Gain” parameter adjusts first delay line’s loudness.
The “Delay 2” parameter adjusts second delay line’s time. The “Delay 2” switch
should be enabled to engage the second delay line.
The “D2 Ph Inv” switch enables phase inversion of the second delay line. This switch
allows you to reduce lower frequencies build-up when Delay 2’s time is close to Delay
1’s time.
The “Delay 2 Gain” parameter adjusts second delay line’s loudness.
The “HP Filter” parameter adjusts the high-pass filter’s (or, alternatively, the low-cut
filter’s) corner frequency. The “HPF Enable” switch enables the high-pass filter.
The “LP Filter” parameter adjusts the low-pass filter’s (or, alternatively, the high-cut
filter’s) corner frequency. The “LPF Enable” switch enables the low-pass filter.
Output
The “Out Gain” knob adjusts the master output signal level.
