Description:
The ProTune firmware update for the GoPro HD Hero2 lowers the audio sample rate from 48 kHz to 32 kHz. There was always some aliasing in the audio even at 48 kHz, but this new lower sample rate introduces even more aliasing in the audio. The sound is so bad that I refuse to use this camera unless GoPro will allow me to revert back to a previous firmware version. nnUPDAT3: I found out how to revert to the previous firmware version, courtesy of Google. I found a link to the firmware on GoPro's web
