 Below is the time measurements of the algorithms. The test measures the generation of 1 second worth of dual-tone at 8KHz sampling rate. For single-tone, just divide the results by two, and for 16KHz dual-tone, just multiply the results by two.
 
-The MIPS value uses the same convention as in [PJMEDIA-MIPS PJMEDIA Performance Measurement] page.
