Patent ID: 7069092

Claim:
A computer implemented method for enabling human comparison of at least some sonic content related to first and second digital audio files, each of which is stored in a memory associated with the computer and both of which comprise substantially similar sonic content, the method comprising: reproducing at least some of the sonic content of the first digital audio file such that a human user can hear the at least some of the sonic content of the first digital audio file; during the step of reproducing the at least some of the sonic content of the first digital audio file, receiving one or more user input signals; in response to the receiving the one or more user input signals, performing the following steps: determining a current position within the sonic content of the first digital audio file wherein the current position represents the at least some of the sonic content of the first digital audio file being reproduced during the step of reproducing at a time when the one or more user input signals are received; based on the current position within the sonic content of the first digital audio file, determining an analogous position within the sonic content of the second digital audio file which corresponds to the current position within the sonic content of the first digital audio file; based on the determined analogous position within the sonic content of the second digital audio file configuring a playback state of the second digital audio file; ceasing reproduction of the sonic content of the first digital audio file at the current position; and based on the configured playback state of the second digital audio file, beginning reproduction of the at least some of the sonic content of the second digital audio file from the analogous position such that the human user can hear the at least some of the sonic content of the second digital audio file and such that switching between reproducing the some of the sonic content of the first and second digital audio files sounds uninterrupted to the human listener.
