who built this
I'm Jonas, a former touring musician from Copenhagen. an illness ended the performing career. I spent three years reading psychoacoustics papers, learning C++, and building the plugins I wanted to use but could not afford.
every KERN plugin starts from published research, has a maximum of five knobs, and runs under 3% CPU on macOS. there are no investors and no employees. just one person and a growing community of producers.
I read every email at jonas@kernaudio.io.
questions
frequently asked.
do I get one key or four? +
one license key unlocks all four paid plugins. enter the same key in SMOOTH, WARM, WIDE, and PUSH.
what if I already own one plugin? +
email support@kernaudio.io with your existing order number. we will work out an upgrade credit.
will future plugins be added to the bundle? +
the bundle includes SMOOTH, WARM, WIDE, and PUSH. future plugins will be sold separately or in a new bundle.
can I try before I buy? +
yes. every KERN plugin has a free demo with the full feature set. the only difference is a brief periodic silence every ~45 seconds. download from each product page.
how many computers can I install on? +
three activations per license key. if you need more, email support@kernaudio.io and we will sort it out.
what order should I use them in? +
SMOOTH first to clean up resonances. WARM next to add character. WIDE last for stereo placement. that said, there are no rules: use them however they sound best on your material.
what happens if I do not like it? +
14-day refund policy. no questions asked. email support@kernaudio.io with your order number and we will process the refund.
