I debated adding this to one of the existing DVD-A threads, but they're getting a little congested.

With DVD-A now rippable, let's use this thread to analyze DVD-A mastering and, if possible, how that mastering compares to the CD version of the album. The primary difference will hopefully be that DVD-As are unaffected (or less affected) by the loudness race.

Here's a look at "Deadwing" by Porcupine Tree.

These are the first four songs of the album from the CD, wavegained to be the same perceived level as the DVD-A.



These are the same four songs from the 5.1 DVD-A, converted to stereo with fb2k. As you can see, quite a bit less compressed. smile.gif



Here's a closeup of the first two peaks of the album from the CD. Note the clipping.



And the same two peaks from the converted 5.1 DVD-A. Goodbye compression!


Album gain, CD: -9.83 db
Album gain, 5.1 DVD-A converted to stereo: +1.08 db

I haven't ripped the stereo PCM layer of the DVD-A yet. We'll see if that's closer to the levels of the CD or the 5.1.

I recorded the different channels of the SACD (sperate analog outputs of the player into 8 channel soundcard), converted them to a multichannel wav-file and used foobar's downmix DSP (Convert 5.1 to stereo).
