This download (zip file) contains the .wav files listed in the table below. Each file contains a short burst of a Maximum Length Sequence (MLS). For each sample rate, the order of the MLS was selected such that the signal length of one complete MLS sequence is approximately 0.100 seconds. The MLS signal is followed by dithered silence (24 bit) to create a total file length of 0.200 seconds. These files can be prepended to a .wav file containing speech, music or noise to improve the signal match in the Transfer Function measurement, as described in Technote 138: Transfer Function Measurements with APx500 Audio Analyzers.
