Recording

There are many ways to record voice digitally. For example, one can use an analog mini-cassette or micro-cassette tape recorder, then playback to the line-in or microphone jack of a computer. This method, however, is slow because the digitization takes as much time as the original length of recording.

A better way to do this is direct digitization. In other words, voice is directly digitized by some device. There are two ways to do this.
