Please note: Of all the recorded talks at Camp Smalltalk Supreme, Dan Ingalls' talk was the only one whose audio track Audacity couldn't amplify very much without clipping. I have no idea why ��� I'm not an audio engineer.So, the amount of amplification is quite modest. However, I did reduce background noise so that you can crank the volume way up on your computer to max. Then you can hear Dan fairly easily.Sorry for the inconvenience.Cheers,Richard
