Our team has been focusing on music and audio related analytics, retrieval, and recognition for almost 20 years. Our goal is to leverage these experiences and technologies to construct the world’s best platform for music-related services and applications. We believe our technologies and development can revolutionize the use of music for edutainment (including music-based games and learning tools) by creating new user experiences and engagement. Such a platform can be achieved through our core technologies for audio, speech, and music processing, including active noise cancellation (over servers and client devices), monaural source separation (for audio music and speech), synchronization of vocal and accompaniment, hardware implementation of pitch shift and vocal removal, singing voice beautification, and so on. With these technologies available at our hand, we can build a variety systems for audio/speech/music services and applications, such as reaction video systems (with enhancement of the user’s recordings), online karaoke services (with singing assessment, and contents from YouTube), microphone-type karaoke (with key transposition for both vocals and accompaniments, with music contents from YouTube), music-based rhythm games (with automatic generated game contents, and with music content from YouTube), music-learning tools (with automatic score following, page turning, and assessment), music retrieval systems (with singing/humming/speech, or original noisy music clips), speech enhancement for noisy environment (in automobiles, for instance), and many others.
