How much hard disk space does a recording use?
This depends on what quality level you want. You can choose from a number of formats and compression methods and select the best compromise. For example full CD stereo quality as a normal .wav file uses 10 Mb per minute: An hour of uncompressed CD stereo quality will be about 600 Mb. Using a speech quality compression format, an hour could be reduced to a little as 40 Mb or less.
