| Audio area, Quantization area, MP3 area, NonCommercialProgs content, G.711_G.72x area | SPDemo is an assisting tool for teaching speech & audio processing techniques developed in SIPL. Using SPDemo one can select from a variety of speech & audio processing techniques and parameters in a straightforward and simple way. The results of this processing are shown both numerically and graphically, in order to ease the analysis of data. The purpose of SPDemo is to enable experiments with different audio & speech processing algorithms without actually implementing them. Free for educational purposes. Created: 05/02/2007 |
| Quantization area, SourceCode content, Papers content | The NeuQuant Neural-Net image quantization algorithm (© Anthony Dekker 1994) is a replacement for the common Median Cut algorithm. It is described in the article Kohonen neural networks for optimal colour quantization in Volume 5, pp 351-367 of the journal Network: Computation in Neural Systems (Institute of Physics Publishing, 1994).
