I like JAM, its a good price and the competition at the pro-end is not as straightforward.

My only doubt is :

after I have spent a long time mastering a client's audio , with high-end conversion and high end bit reduction, to maintain the best possible signal path - what happens to my audio inside the JAM application?

Especially when calculating fades between tracks - I want to know if JAM is re-rendering the precious audio, to calculate the X-fades.

If this is the case, can Roxio guarantee that the digital audio does not lose *any* quality ?

Anybody?

Jon at Roxio?

Roxio cannot guarantee that there will be no loss of quality when calculating fades, because any calculation implies a degradation of the audio (at least that's my understanding). I think I read that in "Mastering Audio", by Bob Katz, but I can't find where. http://www.amazon.com/Mastering-Audio-Scie...r=8-1/qid=11713

Any cross fades rendered by Jam definately change the audio but this change should only occur duing the crossfade. There are a couple of things you can do to minimize artifacts.

1) If you have the choice, import 24-bit versions of all material into Jam. Do NOT dither these to 16 bits in the audio editing program. Let Jam dither them to 16-bit for the CD. Make sure dithering (Advanced Prefs) is turned on in Jam. Jam only provides one dithering algorithm so if you want something different, use the second method.

2) Perform all your crossfades in another editing program and import the entire CD into jam as a single file. Dither the audio to 16 bits in that program and make sure dithering is turne OFF in Jam. You'll either need to use regions to identify track starts or split the final bounce into separate files for each CD track.
