Bitspeek, meanwhile, promises to 'recreate any audio you feed into it using pulse oscillators, white noise and linear prediction filters'. You can find out more at the Sonic Charge website, where Bitspeek can also be purchased for $29 (+VAT). Both plug-ins are PC and Mac compatible and come in VST/AU formats. Review: BitSpeak by Sonic Charge One new plug-in you can. Take Your Music Production. One new plug-in you can add to your utility belt is Bitspeek by Sonic Charge.
Bitspeek is a real-time pitch-excited linear prediction codec effect. Right now you are probably thinking, 'oh, another one of those'? Or perhaps not. Chances are that you have never heard about 'linear prediction', although most of us use it daily when we talk on our cell phones. Linear prediction coding is a voice compression technology that appeared in commercial products in the seventies and was implemented in some well-known speaking toys of the early eighties.

Sonic Charge applied this technology to create a VST / AU effect plug-in that analyzes audio, extracts a number of parameters (including pitch, volume and formant data) and then resynthesizes the audio using a simple oscillator, noise and filter architecture.
A number of playback parameters that adjusts the pitch and tonal quality of the sound as well as support for MIDI and a beat-synchronized 'formant freezing effect' have been added.

Despite having only a few simple controls, this box can produce a broad range of sounds from cheap speaking toys to high-end vocoder and talkbox effects.
