convoLV2 is an LV2 plugin to convolve audio signals without additional
convoLV2 is in an early stage of development and is not yet suitable for
users. However, it serves as a working example of an LV2 plugin with
block length restrictions, in this case:
* Maximum block length must be passed as an instantiate option
* Block length must always be a power of 2 (a required feature)
See the links in the README and on the github page for details about
these features. The first should be trivial to implement in any host,
which is highly recommended. The second may be difficult or impossible,
though it is trivial in hosts that run plugins directly on the Jack
cycle or process files with fixed parameters.
This plugin is intended to provide latency-free synchronous convolution,
which inherently requires these restrictions. It does not, and will not
ever, do latent audio buffering in the plugin itself (though a generic
wrapper to do so is a good idea...)
This release is known to work in Jalv 1.2.0. If you're feeling
adventurous and remove the power of 2 feature requirement from the data,
it will also work in Ardour3. Sometimes. Maybe.
convoLV2 is jointly developed by Robin Gareus (who wrote the entire
plugin before LV2 could properly support it) and David Robillard (who
invented/implemented the missing LV2 pieces).
We hope that convoLV2 will eventually be as fully-featured as IR.lv2
without resorting to kludges that violate the LV2 specification.
This announcement is exclusive to developer mailing lists. Feel free to
reply with any thoughts, and report back with any host implementation
progress so the README can be updated.
 Assuming the Jack block length is a power of 2 anyway, which is not
actually guaranteed, but is true in any case sane enough to care about.
