Default Re: An odd audio CD

Hi Dave
Modern DVD drives no longer seem to have an earphone socket like the old CD drives used to, so no I am not technically playing direct from the drive. But as already mentioned I am playing the CD from the drive via the sound card as opposed to playing a ripped file from the hard disc.

Default Re: An odd audio CD

Hi Mike, yup – that’s what I meant! There is likely very little buffering going on when you use it like that so probably you are hearing the effects of a buffer under-run. It seems possible (to me at least) that a buffer over-run can then cause a subsequent buffer under-run due to rotational latency if the drive is modulating the rotational speed. Even when ‘direct playing’ appears to work the drive will sometimes sound like its working quite hard on an audio CD! In my experience, DVD’s seem to work much better, the compressed format requires vastly more buffering and the disk rotational speed is higher?

I actually find the sound of the drive rather intrusive anyway so I now only listen to ‘ripped’ music! And don’t mention how long it can take to actually recognise an audio CD!
