Opcode Granted U.S. Patent for Audio-to-MIDI/MIDI-to-Audio(TM) Technology
June 3, 1998Opcode Systems, the leading manufacturer of professional music production software and hardware, has announced that the United States Patent Office has granted a patent (U.S. Patent # 5792971) to the company for its ground-breaking Audio-to-MIDI(TM) and MIDI-to-Audio(TM)conversion technology. This advanced digital audio technology is featured in Opcode's popular Studio Vision Pro audio and MIDI sequencing software for Macintosh.
"This patent represents years of work on the part of our programmers," stated Chris Halaby, President of Opcode Systems. "Our goal has always been to deliver powerful, ground-breaking musical tools without adding complexity, and this is proof we've succeeded."
Opcode's patented process allows users to transform any single line digital audio file (human voice, guitar solo, flute etc.) into a MIDI track containing the pitch, timing, dynamics and spectral data of the original file. The resulting MIDI track can be extensively edited like any other MIDI track and then be converted back into digital audio which reflects all MIDI editing changes.
This two-way conversion capability enables users to perform edits and corrections that would be intensely difficult or impossible without it. For example, a lead vocal can be turned into a MIDI track, have its timing corrected, be transposed into a different key, have all pitch fluctuations removed, and then be transformed back into digital audio -- all in a matter of moments.
This patent is testament to the innovation and forward-looking design that has been characteristic of all Opcode products since the release of Studio Vision 1.0, the first sequencer to combine digital audio and MIDI recording.
