Sixth Workshop for LubutoLiteracy Program in Lusaka, Zambia

Slides from the sixth workshop with the children and staff at Lubuto Library at Ngwerere in Lusaka, Zambia. We started our second week with a workshop focusing on sound. A brief overview of analog vs. digital sound recording was delivered. Then we worked on recording, editing and exporting sound in Audacity. Finally, we ended with a demonstration of the MakeyMakey banana piano.

The eight days of workshops I am delivering are funded by a USAID/WorldVision grant from the All Children Reading Challenge. Representatives from the Zambian Ministry of Education participated in all the sessions. Photos here:

The OLPC XO laptop microphone record the sound at a low volume. No problem! Go to Effect > Amplify. No need to change the dB setting. Run a second time. Zoom in on the sound wave using the magnifier button in the toolbar at top right (plus sign in it). Highlight the silent start of the sound wave and trim it off. Do the same with the left over silence after your spoken sound. Save the project. Go to File > Save Project As… There will be a warning about .aup file. Click OK. Name the file, “Name <your name>.” Save in Documents for now.
