Audacity® is an excellent program for making recordings for your classes as either a teacher or a student. The program is simple for a foreign language student to learn by using our basic training, but with advanced training it becomes an excellent tool for audio development. It is available at the excellent price of nothing, being free of charge, as open source software, and available for Window, Mac and Linux. You can download audacity from the project home on sourceforge. If the tutorials here do not answer your questions you can also check there for more information.
