Sonic Charge has introduced Bitspeek – a real-time pitch-excited linear prediction codec effect.
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 has applied the 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.
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.
Bitspeek is available for Mac & Windows for $29. See the Sonic Charge site for audio demos and more info.
