zplane is a research-focused company that provides state-of-the-art music processing/analysis technology and know-how to the music industry. Our passion is to combine our backgrounds, sound engineering, classical musical education, making rock'n'roll with scientific approaches to open up new ways of producing and processing music on computers.


We focus on intelligent signal processing solutions like artifact-free time stretching and pitch shifting and on music analysis technology, dealing with the extraction of high-level musical information from the music signal like tempo, rhythm, melody and key. We make all technologies available for licensing to the music industry in form of ready-to-use SDKs. Hard- and software design and development services are available on various native and DSP platforms and operating systems.
