  • System for sampling rate conversion in digital audio applications
    Patent number: 6661357
    Abstract: A method for upsampling a digital audio signal is described. The method includes receiving a first digital audio signal including samples and having a first sampling rate. The method also includes outputting 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 desired second sampling rate, the second sampling rate being higher than the first sampling rate. The method also includes incrementing a counter for each sample from the first digital audio signal that is output as part of the second digital audio signal. The method also includes, when the counter exceeds a threshold number, inserting at least one synthetic sample as part of the second digital audio signal. The method also includes repeating the outputting, incrementing, and inserting until all the samples in the first digital audio signal have been output.
