Clearroom makes room and headphone calibration software for macOS, built in a working mix room in Chennai, India. Clearroom measures a room with any calibrated measurement mic, scores the measurement before it corrects and refuses a bad one, and corrects towards a target the engineer chooses, playing through the whole Mac or inside the DAW as AU / VST3. Clearroom is the trading name of ULFR Harmonize Private Limited, founded by mixing and mastering engineer Rupendar Venkatesh.
