Patent ID: 7856284

Claim:
A method comprising: acquiring audio data; generating first spectral data at a first resolution of the audio data from a first portion of the audio data; rendering a first spectral display from the first spectral data; generating second spectral data at a second resolution of the audio data from a second portion of the audio data; rendering a second spectral display from the first spectral data and the second spectral data; wherein generating first spectral data at the first resolution of the audio data from the first portion of the audio data includes generating pixel data that are displayed in the first spectral display, the first resolution being a resolution view of pixel data representing the audio data; and wherein generating second spectral data at the second resolution of the audio data from the second portion of the audio data includes generating pixel data that are displayed in the second spectral display, the second resolution being a resolution view of pixel data representing the audio data, the second resolution having a higher resolution spectral display than the first resolution.
