Audacity(R) is one of many useful open sourced free software, initially developed for audio and music applications. It is equally useful when adapted (with some limitations) for exploring bio-sensor data sets, such as EEG, ECG, SCR, etc. Audacity(R) is a free, easy-to-use and multilingual audio editor and recorder for Windows, Mac OS X, GNU/Linux and other operating systems. It is equally useful for editing and analyzing bio-signal data files (in .WAV format) such as EEG, ECG, etc. both in the time domain (waveform) and in the frequency domain (FFT).
