i thought it was hyperbole, but no. there is no other wave file editor on linux besides audacity. tenacity is a fork that, while apparently fixing some political issues and adding some new features, inherits the same fundamental architectural problems.
all other editors for linux are closed. some are free, but you'll have to run their dirty closed-off and possibly backdoored binaries on your pristine omniscient panopticOS.
that means there is a niche for a Cool Edit Pro OSS clone on linux.
