Claim:
1. A method for a device to process digital data, comprising: demodulating wireless radio frequency signals to generate first compressed digital audio data and associated first index data, the first index data comprising compressed digital audio data; demodulating the wireless radio frequency signals to generate second compressed digital audio data and associated second index data, the second index data comprising compressed digital audio data; storing in memory the first compressed digital audio data, the first index data, the second compressed digital audio data, and the second index data; retrieving the first and the second index data from the memory; decompressing the retrieved first index data to generate first decompressed digital audio data; processing the first decompressed digital audio data to generate a first analog audio signal; after a predetermined time period from generating the first analog audio signal, decompressing the retrieved second index data to generate second decompressed digital audio data; processing the second decompressed digital audio data to generate a second analog audio signal; allowing a user to select one of the first or the second compressed digital audio data in response to the first and the second analog audio signals, comprising: retrieving the selected first compressed digital audio data from the memory and decompressing the retrieved first compressed digital audio data to generate third decompressed digital audio data; and processing the third decompressed digital audio data to generate a third analog audio signal.
