of pitch-shifting algorithms are based on time-stretching algorithms combined with resampling. If we want to transpose the pitch by a factor , we can first time-stretch the signal so that the time-stretched signal length is N: where Nis the original length of the signal. Then we resample the signal whose length is N: to have a signal whose length is N.

The élastique algorithm is suited for polyphonic and monophonic material. MPEX. MPEX is an alternative high-quality algorithm. Standard. The Standard algorithm is optimized for CPU-efficient realtime processing. Limitations. Applying time stretching or pitch shifting to audio material can lead to a degradation in audio quality and to audible artifacts.

can someone explain to me what beat markers mean in pitch shifting ? Yes! I recommend reading the User's Manual. From the user's point of view, there are basically two types of time-stretching algorithms: "sliced" and "elastic": (1) Slice-and-move/repitch, like the Propellerheads ReCycle product with its REX file format. Best suited for individual isolated rhythmic instrument tracks: …

Typically, good algorithms allow pitch shifting up to 5 semitones on average or stretching the length by 130%. When time stretching and pitch shifting single instrument recordings you might even be able to achieve a 200% time stretch, or a one-octave pitch shift with no audible loss in quality

The achievable pitch shift is determined by the window length (numel(Window)) and OverlapLength. To see the relationship, note that the equation for speedup factor can be rewritten as: nsemitones = -12*log2(speedupFactor) , and the equation for synthesis hop length can be rewritten as speedupFactor = analysisHopLengh/synthesisHopLength .
