Build the jar with `Files tab\u003ebuild.xml\u003eright click\u003eRun Target\u003eOther Targets\u003epackage-for-store`\n\nBugs:\n- If any of the three singletons crash the whole program becomes unusable\n- Loading a non-audio-file as audio crashes the program\n- Loading a non-vst-folder as a vst crashes the program\n- If you set the gain too high you get really scary aliasing artefacts\n- No spectrograms can be calculated when you are playing audio because jep can only allow python to run in one thread (and I don’t want to pass a multi-megabyte array between two languages)\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fechometerain%2Fampter","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fechometerain%2Fampter","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fechometerain%2Fampter/lists"}
