Apowersoft Free Audio Recorder 4.0

Apowersoft Free Audio Recorder is a program that will record the sound of your computer, either through some video or audio playback, a phone call or video, or the sound that enters the computer through the microphone.

Unlike some of the applications of this type, this program has no limits in terms of size or duration of the recording, beyond what indicates your own hard drive. You can start recording whenever you want and stop recording whenever you want. This program will record what you hear through the speakers.

It's ideal for recording tutorials if you have an image capturer that doesn't record sound, for example.
