Purpose

Convolver applies an impulse response to a signal, so the source takes on the space or character captured in that response. Load an impulse response of a hall, a cabinet, or any captured space, and the input plays as if it were there.

TouchDesigner Use

Insert it inline on a source or feed it from a send so you can blend wet and dry. Wire audio into in and out onward. Set Irfile to the impulse-response WAV, then use Drywet to balance the effect against the dry signal.

Inputs And Outputs

• Input 0: in accepts mono or stereo PCM. It is required.
• Output 0: out emits the same shape as the input.

Main Controls

• Irfile: impulse-response WAV to load.
• Drywet: balance between the dry input and the convolved signal.
• Directgain: level of the dry path, in decibels.
• Wetgain: level of the convolved path, in decibels.
• Normalizeir: levels the loaded response so different files sit at a similar loudness.
• Crossfadems: crossfade time when the impulse response changes, so swaps stay smooth.
• Partitionsize: processing block size for the convolution. Leave at the default unless tuning latency against load.
• Maxirms: longest impulse response length kept, in milliseconds.
• Irchannels and Irsamplerate: describe the loaded response when it is not self-describing.

Notes

• Longer impulse responses give bigger spaces and cost more to process. Maxirms caps how long a response is used.
• Impulse responses can be swapped while audio runs, and Crossfadems keeps the change click-free.
• For a natural blend start with Drywet low and raise it into the space.
