The 1A Equalizer from Audified is software for your macOS or Windows machine that adds tube-based EQ to your audio. Audified has combined vintage tube schematics and modern technology to create this 1A equalizer. It features M/S (mid/side) processing, that separates your audio into mid and side components, allowing you to mix the edges of the stereo signal, while separately sculpting the center. The software also allows you to boost your lows and attenuate your highs, and an analog-style meter shows you your total harmonic distortion.
