Computer digital recording

First, a desktop or notebook computer can be used to perform the digitization in real time. This is hardly a problem from the perspective of resources. Most desktop computers have much more storage space and processing power than necessary to digitize voice (and encode in real time). The problem with this approach, however, is that the microphone must be connected to the computer. In the case of a meeting, that may be possible. However, in a lecture, the lecturer may want to pace and not stay next to a desktop or notebook computer. An expensive solution to this problem is to use wireless microphones.
