1. A device for editing sounds comprising:

  • a memory for storing a sound waveform;

    a display for visually displaying the stored waveform;

    an editor for editing the appearance of a predetermined portion of the visually displayed waveform by manipulation of said visually displayed waveform; and

    means for changing the sound waveform stored in the means for storing in accordance with changes made in the visually displayed waveform by the editor;

    wherein the memory stores a digital representation of the waveform, and the display displays an analog representation of the waveform; and

    wherein the display comprises a display displaying the amplitude of the waveform along a first associated axis and time along a second associated axis;

    wherein the editor comprises;

    means for displaying a sound characteristics control line adjacent to the displayed waveform; and

    means for displacing at least one segment of the sound characteristics control line adjacent to the portion of the displayed waveform;

    wherein the editor comprises mean for altering a specified characteristic of a portion of the stored waveform corresponding to the portion of the displayed waveform adjacent to the displaced line segment.
