Is there an open source library to handle Polar heart rate monitor sound files?

Question

Some of the Polar heart rate monitors can emit training session information using sound. The devices emit a sound like the modems used to do. Are there any Java based libraries to parse these sound files and extract the data? I prefer a Java library, but other implementations are fine too.
