ACE Studio

ACE Studio is an AI vocal synthesis and music production workstation developed by Beijing TimedomAIn Technology in collaboration with Accidental AI. It converts MIDI and lyrics into studio-quality singing vocals, with a library of over 140 royalty-free AI voices spanning styles like pop, rock, cinematic, opera, hip-hop, R&B, and J-Pop/C-Pop, singing in languages including English, Chinese, Japanese, Korean, Spanish, Italian, French, and Portuguese. Users can also train custom voice models from their own vocal samples and combine multiple AI voices in a choir mode. Beyond vocals, the platform generates AI instrument parts from MIDI input, including string sections recorded with the Budapest Art Orchestra, and offers a stem splitter, vocal-to-MIDI conversion with lyric extraction, a voice changer, and a video composer that scores video scenes automatically. It is distributed as a desktop application and is also available as a VST/Audio Unit/AAX plugin for use inside digital audio workstations. ACE Studio opened closed beta in April 2022 and reached a stable 1.8.0 release in October 2023. It suits musicians, producers, and content creators who want vocal or instrumental tracks without booking a singer or session musicians, though results still carry the characteristic texture of synthesized vocals rather than a live recording, and heavier custom-voice or ensemble work benefits from some music production experience.
