A method and apparatus for displaying an audio signal as an improved waveform includes a processor for determining samples of the audio signal which represent a waveform based on positions of pixels in the waveform and a time scale of the waveform, calculating minimum and maximum amplitudes of the samples for each pixel on a time axis and calculating intensities of frequency components of the samples which cannot be represented at the time scale of the waveform. The apparatus includes a display coupled to be in communication with the processor for displaying the samples as an improved waveform of amplitude versus time wherein the intensities of the frequency components are represented in the new waveform by shades of a single colour. |
