Making the Recording with Windows Sound Recorder (Windows XP, NT or Windows 98)

Making the Recording with Adobe Acrobat or Wavesurfer
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.
