2. General Usage
The plug-in is split into the following areas:
• Impulse Response Editing Tab (x2) composed of three sub-tabs
o Impulse responses from files (Wav, WIR, Aiff, SDIR, Flac)
o Early reflections generator
o Synthetic noise tail generator
• Impulse Response EQ Tab (x2)
• Impulse Response Mix Tab
• SplitMod (x2, IR1/IR2) Tab
• Chorus (x3, master and IR1/IR2) Tab
• Stereo Modulated Delay (x3, master and IR1/IR2) Tab
• Post Filter with Modulation Tab
• Settings Tab
• Sample Browser (including lost file management)
• Presets Browser
The IR1 and IR2 tabs control the impulse responses to be used for the convolution reverb. Each
impulse response also has a dedicated filter tab which is applied as an offline process. The mix tab
specifies how the impulse responses are panned and mixed for output. The EQ and Chorus are post
effects that are applied to the convolved data from IR1 and IR2 in real-time.
When processing by the tab is active a subtle illumination behind the tab indicates activity. For
instance if one of the chorus modules is active in a preset this is indicated by a green hue above the
chorus tab. For the mixer tab, any setting that modulates or pans the audio causes the illumination
to show. This allows the user to quickly select presets with or without modulation, or to indicate
where a delay, chorus or modulation effect may be coming from.
Processing Delay
On the settings tab is a pull down to change the processing delay associated with the convolution
engine. This can be selected from a range of values and applies to all audio processes. Selecting a
higher delay typically reduces CPU load. Much effort has gone into optimising the plug-in for
efficient operation at zero delay and on a modern processor picking a higher blocking size may be
unnecessary.
It should be possible to use the plug-in at zero delay in any host regardless of block size and
whatever internal scheme is used to provide the plug-in with samples. Some hosts provide non-
