Pitch Drift is a free AUv3 effect plugin by Baby Audio that introduces organic-sounding pitch fluctuations. It can range from subtle instabilities that make your instruments sound more natural and less sterile – to intense pitch drifting that will make your tracks clearly out of tune. Controls: Pitch Drift lets you control the depth and speed of the pitch fluctuations in a simple interface. It is powered by the "Drift" algorithm in Baby Audio's Super VHS plugin and offers the same natural and pleasing fluctuation effect. Inspired by real instruments: One of the appeals of acoustic instruments is that they are never 100% in tune 100% of the time. These subtle pitch fluctuations compound when you bring multiple instruments together in a mix, making the music sound richer and more dynamic. However, in the computer-era this concept is sometimes lost. Pitch Drift makes it fast and easy to break the spell of digital pitch perfection and get your tracks to vibrate a little more. It generally works best at subtle levels on sustained tonal instruments or entire mix busses. As a rule of thumb, the less sustained your source is, the faster you want the speed parameter to be set.
