Hello! First off, I'm thoroughly enjoying Duolingo. Fantastic site and app. I don't usually use the dictation option though, as my computer seems to garble the audio on playback. Does anyone else have this problem?
The garbled playback is the result of high reduction in bit rate. They do this to keep the bandwidth low. It seems that every time you press the playback, it downloads your spoken audio and plays instead of using a local copy of the file.
