About Defsound Labs
Defsound Labs is an audio software brand operated by RAVISSA, K.K. in Japan.
We create audio tools for producers, mixers, and music creators who want to move faster without losing control of the sound.
Our products are designed by an active producer and mixing engineer, with a focus on practical sound, simple workflows, and controls that make sense in real sessions.
Instead of adding unnecessary complexity, Defsound Labs focuses on tools that help shape tone, space, movement, and mix balance quickly.
For purchases made through our online store, checkout, payment processing, taxes, and invoicing may be handled by FastSpring, which may act as the Merchant of Record for the transaction.
