Z-DSP Cartridge - Mariana TrenchMariana Trench is a FDN card for the Z DSP. Feedback Delay Networks (FDNs) are built around multiple delays which are connected to their inputs thanks to a feedback matrix designed for its stability and lossless properties. FDN can mimic the recursive process of sound waves bouncing back and forth in an acoustic space. They were first suggested for artificial reverberation by Michael Gerzon (1971) and later John Stautner and Miller Puckette (1982)

This is a terrific sunscreen for those looking to tan faster. It's not as low as 8 SPF, or as high as the minimum recommended 30 SPF, but it'll get you darker faster. Apply this 15 minutes before going in the sun, and reapply every two hours. As someone who recently went to Hawaii and got 2-3 hours of sun every other day for two weeks, reapplying is absolutely crucial. We went once and reapplied after three hours, and that gave us some pain. Not as much pain as not reapplying at all, but it definitely taught us to reapply no matter what, if you are in the sun. Overall, this applied cleanly and protected our skin about 93%. And 93% is better than not wearing any sunscreen at all.
