Old school warbly malfunctioning tape delay Nebulizer comes echoing back from the IAA doldrums. But fear not. Even though it's now an AUv3 effect plugin, ready to stack up on multiple tracks in GarageBand, AUM or your favourite audio application, it's still the wayward lo-fi monstrosity you used to know. And if you didn't know it, isn't it about time you did? Nebulizer is totally free. No ads, no in-app purchases, no subscriptions, no surveillance, no nag screens. If you want premium features, this is not the app for you.
