Time Stretch Vst Plugin Free

/ Comments off

Velocity and mapping can be handled by drawing a custom curve or using the integrated knobs. The plugin also acts as a bus so you can send in and out effects in real-time. TX16W has 64-bit support and has a built-in arpeggiator, for a paid add-on, you can have time-stretch and pitch-bend modes. For free or otherwise, this plugin is no joke.

Time stretching (and time expanding !) is an useful feature for those who produces remixes, mashup / bootleg, or want special FX.
Time stretching consists in changing the speed of a sound without changing its pitch.
The inverse operation is called pitch shifting : changing the pitch without modifying the speed.

Wavosaur has no native timestretch feature but Wavosaur has two pitch modifiers :

– Simple pitch shift
– High precision FFT pitch shift

The simple pitch shift modify the speed when you change the pitch : it acts like a goold old turntable if you set your 33 rpm LP record to 45 rpm => pitch increase ! welcome to the chipmunks.

The High precision FFT pitch shift is a special effect for changing the pitch without changing the speed.

These two features are in the “Process menu”
and now the magic :

High precision FFT pitch shift+ simple pitch shift=time stretch / expand !!

Let’s try with a vocal sample, open it in Wavosaur :

now go to menu -> Process -> Pitch Shift -> High precision FFT, and let’s change the pitch to an extreme setting : X 2 (one octave higher)

and now, go back to the original pitch : menu -> Process -> Pitch Shift -> Simple : and now set the pitch one octave lower ( – 12 semitones) : this will also change the speed (two times slower)

with these two operations you obtain a time stretch / expand : pitch is the same, but speed as changed ! This is more effective for voices, solo tracks… but don’t hesitate to experiments.

Just don’t forget your calculator, if you need to make something less trivial than one octave up / down.
