One Master provides AI mastering, AI mixing and a browser-based multitrack studio without installation or plugins. AI Master accepts finished mixes or separate beat and vocal files and creates a 24-bit WAV master. Seven genre presets or a WAV reference track are available for single-file mastering. AI Mixing combines two to eight stems into a stereo WAV and can apply mastering in the same run. The Studio supports multitrack arrangement, piano-roll parts, built-in instruments, microphone recording, mixing and AI mastering. A free account includes one Studio project, and complete masters and mixes can be heard free. Studio exports require a Studio Pass or one Studio credit; that credit permanently unlocks the project’s exports. Inputs are limited to 10 minutes. Paid song plans start at 9.90 USD per once and include WAV downloads, three revisions and permanent file retention.
