AC vocoder

VPS Glitch Bitch is your new favourite tool, when it comes to mangle your audio tracks: shorten or increase buffer sizes, sync buffers to your host tempo, add HP- or LP filters, apply rate reducing, reverse the buffers, use the ‘advance buffer mode’ to create unheard effects, pitch down your buffers, apply volume and pan modulations, draw. Blittr is a free glitch and stutter and buffer synth and lfo VST plugin developed by ArcDev Noise Industries. Compatible OS(s): Windows. Blittr is a buffer-sampling, stuttering glitchbox in the tradition of DFX’s Buffer override. It features integrated modulation LFOs, XY pad and a useless-but-cool-looking wave scope.

BufferOverride 2.0

Free VST plug in BufferOverride 2.0Buffer Override can overcome your host app's audio processing buffer size and then (unsuccessfully) override that new buffer size to be a smaller buffer size. It makes a lot more sense if you just try it out and hear what it does. It can sound like a stuttery vocoder or a stuck beat shuffler or many other delightful things. In certain hosts, you can also 'play' Buffer Override via MIDI notes and even sync it to song tempo.

TrashCoder

Trashcoder is a small interesting Plug-In with great vocoder powers to produce warm analog sounds and trashy hard sounds. Trashcoder simulates an analog vocoder and has extra modulation features.
The vocoder effect is amazingly adjustable and comes with vocoder filterbank shaper, sound morph levels and extra cutting modulation. All this in one free Plug-In.
This real-time effect can make classic vocoder sounds like robot voice and morphing. It also comes with new sharp cutting sounds, overtone enhancer and dirty trash sounds.
- Works in real-time
- Any VST track can be carrier sound and speech sound
- Vocoder filterbank shaper morph hardness level
- Cutting modulator frequency
- Input carrier and speech gain output gain
- Switch for carrier and speech routing

Buffer Override Vst Download Full

The center is the most important part. That is where the big black box is, which is the crux of Buffer Override. That box is a 2-parameter 'XY' control. Left-right movements control the buffer divisor parameter. Up-down movements control the forced buffer size parameter. The tempo sync button above the box corresponds to the forced buffer size.

The lower left corner has controls for an LFO that can modulate the buffer divisor. The lower right corner has controls for an LFO that can modulate the forced buffer size.

The upper left corner has stuff relating to MIDI. The upper right corner has mix-related stuff.

forced buffer size:

This is the size of Buffer Override's own buffer. It is thrust upon the host with little regard for the real audio buffer size. You can control it by dragging up and down in the XY box or by clicking and dragging up and down on its numerical value display (which is located underneath the XY box).

If buffer tempo sync is turned on, then the forced buffer size is adapted to the tempo of your song. The values are in buffers per beat (note: I mean per single beat, not per measure, so this is time signature independent). Otherwise the forced buffer size is in milliseconds.

buffer tempo sync:

This switches between 'free' and tempo-synced forced buffer size control. This is the tempo sync button that is directly above the XY box.

buffer divisor:

This number is divided into the forced buffer size, resulting in the mini-buffer size. It determines how many times each forced buffer 'skips.' You can control it by dragging left and righ
