élastique time stretching & pitch shifting SDKs

Test the amazing quality with the real-time pitch shifting plugin

 

 

zplane's élastique family offers three different time-stretching (aka time-scaling, master tempo or key lock) and pitch shifting (aka pitch scaling or key lock) engines, optimized for different use cases: élastique Pro, élastique efficient, and élastique SOLOIST. All three of them are able to run in realtime.

élastique Pro

élastique Pro is a general purpose time-stretching engine that offers unmatched quality and easily fulfills the high quality demands of professional productions and broadcast applications. The time-stretching engine is based on state-of-the-art psychoacoustic models and signal processing theory. élastique Pro is based on a completely new approach to time-stretching, making stretching artifacts obsolete and thus providing sharp transients and crystal clear vocals without phasing artifacts. élastique Pro offers stable timing, inter-channel phase coherence and sample accurate stretching. As a special feature, élastique Pro allows you to do formant preserving pitch shifting not only for monophonic, but also for polyphonic input files to avoid the well-known mickey-mouse effect when pitching up or down. Last but not least, all of this can be done in real-time on current CPUs.
Pro is the pitch shifting engine used in our Elastique Pitch Plugin.

Additionally, the élastique Pro SDK package makes élastique efficient and élastique SOLOIST accessable through the same API to make integration of different processing modes as easy as possible - no additional fee required!

élastique efficient

élastique efficient gives you great time-stretching quality at a stunning workload efficiency. The algorithm is targeted at complex polyphonic signals like complete mixes etc. efficient uses specifically developed technologies to efficiently detect tonal and transient components with high accuracy in the frequency and time domain. It furthermore offers different mechanisms to improve performance even more: the processing can be split into several parts in order to avoid workload peaks at low latencies and the overall bandwidth can be reduced in order to save more processing power (at the price of a slightly decreased quality level).

élastique SOLOIST

élastique SOLOIST is targeted at monophonic input signals. Thanks to this restriction, it offers incredible quality for this type of input. It allows pitch shifting with formant preservation to leave the sound's timbre/formant characteristics untouched, and has a transient copying feature to preserve crisp attacks. SOLOIST also allows to split the analysis and the synthesis part of the processing to implement a incredibly efficient real-time synthesis when the analysis is done offline. SOLOIST offers a low level API that requires experienced audio programmers - when interested in an easy to use SDK for pitch correction check out our elastique Tune SDK.
SOLOIST is the pitch shifting used in our instant harmony plugin vielklang.

in the press

  • Electronic Musician (Feb 11) on zplane Elastique Pitch Plugin: "(...), Elastique Pitch is currently the highest-quality pitch-shifting plug-in I've heard in AU format. (...), it's a must-have for music, voice-over, and multimedia work. "
  • Electronic Musician (Jan 10) on Sony Sound Forge Pro 10: "For time-stretching, I particularly liked the sound of élastique Pro on vocal material (...)"
  • Mix Magazine (May 09) on zplane Elastique Pitch Plugin: "To my ears, the plug-in sounds great (...) With any sound source that I tested it on, from full-frequency final stereo mixes to monotone spoken-word vocals, the artifacts rarely limited any reasonable sonic possibilities."
  • Remix Magazine (May 09) on ACID Pro 7: "With all this radical stretching, Sony wisely updated the core time-and-pitch engine with the hot new Elastique Pro algorithm from Zplane. Selectable from an audio file's clip properties window, Elastique is more of a lossless algorithm than the stock Acid method, allowing you to really stretch events with minimal sonic artifacts."
  • Radio and Production (Jan 09) on ACID Pro 7: "The programs ability to stretch and shrink music beyond recognition, almost without artifacts, is amazing. "
  • ElectronicMusician (February 08) on Tracktion 3: "Tracktion 3 also features impressive new algorithms for time-stretching and pitch-shifting. (...) Even fairly substantial time-stretches and pitch-shifts sounded natural and unprocessed."
  • SoundOnSound (June 06) on ableton live: "Live's stretch algorithms are ideal for 'general purpose' stretching, although the Complex algorithm is uniquely wonderful and can often provide the best possible stretched sound for complex material."
  • ComputerMusic (August 07) on Tracktion 3: "Elastique fantastic: On top of this, Mackie have implemented the excellent Elastique Efficient timestretch/pitchshift algorithm, making audio timestretching, root shifting and formant manipulation more precise and laden with fewer artifacts."
  • AudioMidi.com (June 07) on Electro ID: "I think the time-stretching sounds smooth and professional, even at extreme settings."
  • amazona.de (June 06) on The Resource: "Der Unterschied ist hörbar! Der MPEX-Algorhythmus zeigt deutliche Schwächen - der neue zplane-Algorhythmus verrichtet seine Arbeit gut."
  • SoundOnSound (March 05) on FLStudio 5: "Another major upgrade to the basic FL Studio package is sample time-stretching and repitching. Image Line told me that their new stretching algorithm was the best in the world. I can't substantiate that claim, but I know it is darn good."
