Sound Wave Recorder is a very simple and free software to record audio. With the help of this program you can record sound via a microphone, and save it on your PC in a WAV file.
It includes a large number of exit options: 44100, 22050, 11025 and 8000 Hz, stereo or mono channels, different bitrates ... everything to get the exact quality you want. As in any conventional recorder, you can play, pause, stop and record. The only hardware requirements of Sound Wave Recorder are a sound card and, as is logical, a microphone.
