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
