Abstract

In researching Additive (sinusoidal) Synthesis, GAD Group's Martin Simpson has developed an alternative to existing conventional techniques for deconstructing, reconstructing and understanding signals as individual sinusoids. His new technique does not utilise Fourier (such as STFT) or Wavelet Transforms and presents a viable, if not superior way to analyse signals with greater precision. For example, in one audio implementation, GAD Signal Processing (GSP) is capable of simultaneously discriminating frequency, phase and amplitude information for all sinusoidal components of a signal in real time, providing the information needed for Additive Synthesis.

GSP is a new technology, and GAD Group (its publishers) are keen to partner with researchers involved in the various areas of DSP to further test and validate the technology. Current in house development is being focused on Source Signal Separation in preparation for the ICA 2007 Conference.
