Wikivoices episode 48 is different. Typically a Wikivoices episode is typically a topical conversion of a group of people. This time, Adam Cuerden took the initiative to explain how to edit historic sound files.
He explains what to do with a great performance of Emmy Destin who recorded Rusalka of Antonin Dvorak in 1915 in Campden. Emmy Destin was a prima donna in her time and it is a great performance.
Recording of a phonograph cylinder has its hisses and ticks and Adam does a great job explaining how to use Audacity for the restoration of sound files. Audacity is a great tool for the job, there is an implementation for Windows, Macintosh and Linux and there is a localisation in many languages.
The combination of an explanation in sound and text makes for an exeptional and superb Wikivoices episode.
