Hi all! I don't cnow where can i ask about this and I hope you can halp me. I have a digital voice recorder olymus ds-2300, it's working with *.dss files (digital speech standart). There is Olympus Dss Player for Windows but nathing can play it with linux. On olympus development homepage i found "Sound SDK for WIndows" but they don't wont to make it open. Please can you look at this and say, wo i need to looking for. What kind of codec it use. Here is marked differenc between two files. On begin they are almost same and the differnece i marked with "^", and in sound section same parts i marked with "=". Thenk you.
