Blindfold EQ is a freeware EQ plugin developed by AudioThing Ltd. It is a unique and innovative tool that challenges traditional EQ plugins by removing all visual indicators and forcing users to rely solely on their ears. Inspired by a quote from Matt Wallace in the book "Recording Unhinged" by Sylvia Massy, Blindfold EQ offers an unconventional approach to audio equalization.

The plugin features four bands - LowShelf, LowMid, HighMid, and HighShelf - each with a blind knob. Unlike traditional EQ plugins, Blindfold EQ does not display any indicators or numbers to show frequency values, gain values, or Q values. Instead, users are encouraged to trust their ears and make adjustments based on sound alone. This approach promotes a more intuitive and creative process, allowing users to rely on their musical instincts rather than technical measurements.

Blindfold EQ is available as a free download for iPhone users. With its unique concept and minimalist design, it offers a fresh perspective on audio equalization and encourages users to explore new sonic possibilities. Whether you're a seasoned audio professional or an aspiring musician, Blindfold EQ provides a refreshing and challenging EQ experience.
