Hi folks:
I newly got a OMAPL137 board. I want to sample non audio signals and make some wavelet-related processing. The OMAPL137 board only got a audio line in jacket. My confusion is how can I get non-audio signals sampled using this board?

It sounds like you'll need to make an adaptor. I am not sure what your specific situation is, but you could take an audio cable, cut one end off, and wire it or solder it to the signal you are trying to sample.
