NASPRO free development-tool | adapter by NASPRO development team

NASPRO is a free development tool and adapter LV2, DSSI, Ladspa plugin developed by NASPRO development team. Compatible OS(s): Linux.

NASPRO is meant to be a cross-platform sound processing software architecture built around the LV2 plug-in standard.

The goal of the project is to develop a series of tools to make it easy and convenient to use LV2 for sound processing on any (relevant) platform and for everybody: end users, host developers, plugin developers, distributors and scientists/researchers.

This release is a total redesign/rewrite that more or less re-implements the features of the previous release, but in a much cleaner and maintainable way.

It includes:

  • NASPRO core: the portable runtime library at the bottom of the architecture.
  • NASPRO Bridge it: a little helper library to develop insert-your-API-here to LV2 bridges.
  • NASPRO bridges: a collection of bridges to LV2 which, once installed, allow you to use plug-ins developed for other plugin standards in LV2 hosts. In particular, the NASPRO bridges collection includes two bridges: a LADSPA 1.1 and a DSSI 1.0.0/1.1.0 bridge.

All of the code is released under the LGPL 2.1 license.

More information is available on the project’s website.
