Open source FSK decoder library? [closed]

问题:

I'm looking for a library or tool to decode FSK in wav files, e.g. caller id.

Currently using the tools bundled with vpb-driver for Voicetronix hardware that is available via debian/ubuntu. But this appears to have an error that I'm trying to debug -- a second tool to validate the audio file would be useful.

I'm not looking for any of the myriad tools that read caller id data from a modem or other hardware device -- I need pure software.

Try SpanDSP http://www.soft-switch.org/

Lots of good stuff in there, including FSK.
