Here is a small audio ITC software, inspired from EVPmaker (EVPmaker was created by Stefan Bion). This plays short sequences of an audio file, in the chosen language, and randomly. The randomness is produced by a javascript function, inside your computer. You can also visit our other audio streams there.
There is a possibility here to record from your microphone, but the quality is poor and we rather recommend to use another software like WavePad which does not use the microphone, but directly records the internal desktop audio.
