The above diagram shows the sounds I made during sleep while suffering from Obstructive Sleep Apnoea before using CPAP.

The total duration is about 1 minute 15 seconds, and the periods of silence are 'apnoeas' during which I stopped breathing for more than 10 seconds.

The sounds that I made were not snoring, but frightening 'gasps' for breath, the last one I actually cry out in desperation !
All of this I was unaware, except for the symptoms of OSA during the day.

Below is the recorded sound of the wave in the diagram above, in real time, it is in mp3 format, and should be playable by most modern computers.
You will have to wait about 1 minute for the file to download to your computer if you have a dial-up connection (usually 56Kbps modem)
