zplane élastique audio stretching and pitch shifting

Cakewalk now supports industry standard élastique Pro V3 by zplane.development as a time stretching engine, for both online and offline rendering. élastique is deeply integrated into Cakewalk across the entire ecosystem of AudioSnap and time/pitch processing operations. Two new stretch methods, Elastique Efficient and Elastique Pro, are now available as new stretch methods throughout the application (Elastique Efficient is now the default online stretch method instead of Groove stretching).

Benefits

élastique has several advantages over other stretch methods, including:

Real-time stretching has much higher quality than Groove or Percussion stretching algorithms.

Transparent, high quality pitch shifting and time stretching.

More efficient memory use.

Very fast and efficient processing for both Elastique Efficient and Elastique Pro algorithms.

Transient preservation without phasing artifacts.

Formant preserving pitch shifting for both monophonic and polyphonic material.

Use cases

élastique is integrated across the entire ecosystem of AudioSnap and time/pitch processing operations. It is available for use in the following use cases:

Slip stretching regular audio clips (see Slip-stretching audio and To stretch an audio clip).

Using AudioSnap clips (see AudioSnap).

Stretching audio clips to automatically follow the project tempo (see To sync an audio clip to the project tempo and Clip follows project tempo).

Using the Process > Transpose command (see Process > Transpose).

Using the Process > Quantize and Process > Groove Quantize commands to quantize AudioSnap beats (see To quantize audio to the project’s Time Ruler and To Groove Quantize an audio clip).

Using the Process > Length command (see Process > Length and Stretching and shrinking events).

Using the Process > Fit to Time command (see Process > Fit to Time and Stretching and shrinking events).

Using VocalSync clips (see VocalSync automatic audio alignment and To specify default render modes for new VocalSync clips).

To enable élastique

To specify the default stretch methods, go to Edit > Preferences > Audio - Playback and Recording and select the desired default Online Render and Offline Render modes under Stretch Methods. The online render mode is used for real-time playback, and the offline render mode is used for export, freeze, and bounce. For details, see Algorithms and rendering.

There are two new stretch methods:

Elastique Pro is a general purpose high quality time-stretching engine that fulfills the demands of professional productions and broadcast applications. It minimizes stretching artifacts, offers stable timing, inter-channel phase coherence and sample accurate stretching which allows for sharp transients and crystal clear vocals.

Elastique Efficient gives you similar time-stretching quality as Elastique Pro, but with a lower CPU hit. The algorithm is targeted at complex polyphonic signals like complete mixes and offers the same transient preservation as Elastique Pro.

 

Note: You can override the default stretch method at the track and clip level by selecting a different Online Render or Offline Render setting in the Clip Properties Inspector, Track Properties Inspector, or AudioSnap palette.

Backward compatibility

élastique is only available in Cakewalk release 2018.09 and higher. Because prior versions of Cakewalk (or SONAR) do not support this feature, projects utilizing élastique as a stretch method will not render properly in prior versions. A warning message will be displayed when you open a new Cakewalk project in an older version of the software.

If you need to share project files with a prior version of Cakewalk, select one of the older stretch methods before saving the project. Alternatively, you can reset the stretch method in the earlier version of Cakewalk.
