These applications provide more recording options than the Window Sound Recorder application. They should be set up for monophonic recordings at a sample rate of about 11,000 samples per second in order to save recording space while still retaining reasonable fidelity. The number of bits per word should be 16 bits to allow the full dynamic range available in the sound card. The larger resolution size of 32 bits floating point would be a waste of space and computing power.
