Plurality Language's Foreign Service Institute Courses are among the finest self instructional language courses available today. Re-Mastered in 2011, only Plurality Language's FSI course material has been digitally edited to provide better sound quality than the original recordings themselves. Plurality Language pioneered the digital evolution of FSI language courses, by becoming the first publisher to make them available on compact disc, as they were only available on audio cassette. Now, all courses are offered as MP3 files, with better audio quality than the original cassette or compact disc, and we can prove it through wav file analysis. The works been done, the courses are great, and now they're offered at a fraction of the cost of what the government still sells them for on cassette.
