If audio sounds sped up when playing back in the DDP Player program you should check the settings on your computer’s soundcard and ensure that the sample rate is set to a setting similar to one of the following; 44100HZ, 44.1Khz, or “CD quality”.
If you experience digital pops/glitches/stuttering audio while playing back the DDP file in the player, you can go under the “Tools” menu in DDP Player, select “Settings”, and then choose “Audio Settings”. Increasing the “Audio Buffer Size” setting should eliminate these artifacts. 1024 samples is a good setting to try!
An Audio CD burnt from DDP Player should eliminate both of these issues if you cannot make the changes above.
