And plus there has to be limits, or at least very simple "prerequisites", so: the software, whether sequencer, virtual instrument or plug-in should have both time-stretch and pitch shift capabilities. It’s difficult to be truly exhaustive in such a test.

So let’s take a look at the software that’ll be used for this comparison. But maybe it would be better to take a look at this Wikipedia article to learn some of the basics, and it also has some very well-chosen links that can give further information on both technologies. Certain programs allow you to work on formants separately via independent or automatic adjustments. As for pitch shift, it has to, of course, maintain the same tempo (sometimes also referred to as Frequency Shift), while avoiding audio artifacts, and the chipmunk effect or the "voice from beyond the grave". Some technologies include: phase vocoder, time domain harmonic scaling, sinusoidal/spectral modeling, granular re-synthesis, additive re-synthesis, neural networks, the wavelet transform, and so on. On top of that, it must preserve phase, transients, placement, stereo, etc. Time stretch and pitch-shift are two good examples: how is it possible to change pitch to such an extant without getting a horrible sound? Whatever technology is used, it often consists of just filling in holes and spaces, which requires extremely precise interpolation calculation, in the case of Time stretch, and harmonic and formant alteration in the case of pitch-shift. We sometimes get so used to the changes and/or new features offered by digital audio that we tend to become jaded and don’t realize the incredible possibilities that digital audio offers. The first can speed up or slow down an audio file without changing its pitch, the second change its pitch without changing its tempo (otherwise, it’s back to tapes and vari-speed. We'll be dealing with two important features that have more or less created a revolution in music since their arrival with the earliest samplers: time-stretching and pitch-shifting. Is this good or bad? Everyone has their own opinion but certain features have been improved, some totally new ones have emerged, while others are less effective or successful (knowing that many opinions are primarily subjective).īut the goal here is not to make (empty) comparisons between the two worlds.

The competitors: 26 Mac and PC programs, from big sequencers to small applications, plug-ins to audio editorsĭigital audio has brought about many changes to the audio world when compared to analog. OK, here we go! This is the first of our comparative software tests on time-stretching and pitch-shifting.
