Music Audio DVD
 

I'm having a play with my new Apple computer, and I've noticed this
feature in the Toast CD burning softwa

Music Audio DVD

By default, Toast records Music DVDs in Dolby Digital 192 kbps audio.
This compresses the audio to maximize disc space to fit over 50 hours of
music, but maintains full Hollywood-style fidelity.

OK fine - is this Hollywood fidelity any good? It continues:

To change the audio format from Dolby Digital to uncompressed PCM audio,
click More and choose the Custom option from the Encoding tab. Choose
PCM for the Audio Format.

I'd assume this is the one to use for a 'perfect' CD copy on to DVD? It
goes on:

---
Toast records PCM at 48 kHz / 16 bit levels, which is higher than
standard CD quality, and exceeds the levels of most songs in your iTunes
library. Audio that has been recorded at 96 kHz / 24 bit is downsampled
automatically unless you choose the 96 kHz / 24 bit option, which
maintains the higher quality but significantly reduces disc space.

---
I don't see how the software 'records' - encodes maybe? And so leave
that 96/24 option for compiling a DVD from CD?

And switch it on for LP rips? :-)

If you are wanting to make 'perfect' copies of audio CD data, then the snag
with the above is that it implies the information is sample-rate converted
from 44.1 to 48 ksamples/sec. This conversion may be done so well that any
degredation is inaudible/irrelevant, but it won't be a 'bit identical'
copy.

Slainte,

Ah, thanks. I tried a DVD. During the preparation in software there was
a pause while it did something, and the processors went up to 90% each
(never seen that before, even with video encoding), so that's the
conversion taking place then. But as for sound - sounds fine to me :-)
The only problem in use is the pause between tracks, and that can't be
changed in software.
