My objective has not been to find a method for automatic splicing, but to do nice cross-fades at given splice points. There were multiple objectives: * Intuitive definition of the cross-fade shape. Mixing ratio as a function of time is a good definition. * For stationary signals, there should be no clicks or transients produced. This is taken care of by the smoothness of the cross-fade envelopes. * For stationary signals, the resulting measurable transition from the volume level of signal 1 to volume level of signal 2 should follow the chosen cross-fade shape. This can be accomplished knowing the volume levels of the two signals and the correlation coefficient between the two signals. -olli -- dupswapdrop -- the music-dsp mailing list and website: subscription info, FAQ, source code archive, list archive, book reviews, dsp links http://music.columbia.edu/cmc/music-dsp http://music.columbia.edu/mailman/listinfo/music-dsp
