Method and system for universal sampling rate conversion

Abstract

A sampling rate converter (100) is provided. The system can include a data buffer (102), a processor (104) for processing data in the buffer (10), and a plurality of sampling rate lines for configuring the processor. For example, the input signal can have an input sampling frequency corresponding to a first sampling rate line (110) and an output signal having an output sampling frequency corresponding to a second sampling rate line (112). The processor (104) can convert the input samples corresponding to the first sampling rate to output samples corresponding to the second sampling rate using a single filter (700). The first line (110) can include approximate sampling rates of 8 kHz, 16 kHz, 32 kHz, and 64 kHz; the second line (112) can include approximate sampling rates of 12 kHz, 48 kHz, and 96 kHz; and the third line (114) can include approximate sampling rates of 11.025 kHz, 22.05 kHz, and 44.1 kHz.
