Abstract:
A system, comprising:a processor; at least one storage system coupled to the processor; an audio output control mechanism stored in the at least one storage system and configured to receive a first digital audio signal having samples; an upsampling mechanism stored in the at least one storage system and configured to (a) determine a first sampling rate of the first digital audio signal, (b) output at least one sample from the first digital audio signal as part of a second digital audio signal, the second digital audio signal having a second sampling rate, the second sample rate being higher than the first sampling rate, (c) increment a first counter for each sample from the first digital audio signal that is output as part of the second digital audio signal, (d) insert at least one synthetic sample as part of the second digital audio signal when the first counter exceeds a threshold number, (e) repeat (b), (c) and (d) until all samples in the first digital audio signal have been output.
