Well, there are other methods - 16 bits _is_ enough given logarithmic quantizising. I believe that there may very well be schemes for lossy compression that aren't detectable. After all, a vinyl record has it's own imperfections. I certainly believe that, given a quantizising method and bitrate (say 16bit linear and 44kHz) there are methods to reduce the amount of information being transferred without losing sound quality - since the losses are below the treshold of the quantizising system itself. -- Jon W{tte h+@nada.kth.se - Power !
