Frettable - Software Developer

Frettable is a music technology company that specializes in automatic instrument transcription. Think speech recognition but for music: a musician plays their instrument and near-instantaneously receives sheet music indicating the notes that were performed. Frettable brings advanced artificial intelligence out of the lab and onto mobile devices to empower musicians with quality transcriptions and song writing tools anytime, anywhere.
