Reverb Installation

PostSat Dec 21, 2019 5:30 pm

I would like to enter my own reverb impulses into Hauptwerk. The information in the help screen is very sparse. It would be a HUGE help if someone could provide an example impulse installation file of the form: *.ImpulseResponseReverbDefinition_Hauptwerk_xml.

The CODM example files were a big help in illustrating proper CODM file format.
Similarly, an example reverb installation file would be much appreciated.

These are the raw rules. But I think it will require a lot of trial and error to come up with an actual file that will load. I was just hoping to avoid that by looking at an example in the proper form.

Hello Al,

You could simply look at the impulse response reverb definition (XML) files for the the 18 reverbs that are pre-installed with Hauptwerk v5. They're in the HauptwerkSampleSetsAndComponents/ImpulseResponseReverbs folder. (The v5 default installation locations are within your computer account's home folder.)
Best regards, Martin.

Hello Martin,

I don't think you understood my question. The files in the "HauptwerkSampleSetsAndComponents/ImpulseResponseReverbs" folder are the RESULT of installing a reverb installation file. I was asking about the form of the installation file.

Also, the help file says that the impulses are "true stereo" with 4 channels. How does a stereo waveform have more than 2 channels?

Hello Al,

Please see the 'Design tools | View Custom Organ Design Module, installation package, temperament, and reverb format documentation' menu item, which covers all of those things in the 'Section 5: Impulse response reverb definition file tables' section.

Briefly, in summary:

- Reverbs need to be packaged for Hauptwerk's component installer via WinRAR/RAR.

- 'True stereo' impulse response reverbs (whether for Hauptwerk or any other convolution application) have four channels, with one channel for each of the four possible source-to-destination channel mappings. In Hauptwerk's case the order of the channels (source->destination) is L->L, L->R, R->L, R->R, which is the same channel order that Cubase's convolver uses/requires, for example. If you look around on the Internet or in audio engineering books you will probably find plenty of information on recording/creating true stereo acoustic impulse responses.
Best regards, Martin.

Sorry to have bothered you Martin.
I'm going to drop the subject because:
1) All the impulses I have are stereo wav files (they work fine with Reverberate),
2) I only have audio tools that work with 2-channel wav files,
3) I think on-the-fly convolution is mainly a toy anyway since the best sample sets are recorded with real reverb which will always sound better than fake. :D

All the best,
Al Morse

Thanks, Al.

No problem. (By the way, the freeware Audacity does support 4-channel files. You could also potentially convert 2-channel impulses to 4-channel by duplicating the relevant channels, although the result would never sound quite as convincing as using 'true' 4-channel impulse responses.)
Best regards, Martin.
