I've noticed a strange thing lately as I started experimenting with the PS3 as a media center. I want to stream audio from my computer but will not do it unless it matches the audio quality of the CD. My plan was to save everything as .wav files (iTunes calles it PCM, 16 bit stereo).
Anyway please read below about my comparisons between CD, AAC, MP3, and PCM on the PS3.
When I play a CD, my receiver says STEREO PCM.
When I play AAC, MP3's, or PCM (from my computer) it says MULTICHANNEL.
Now even though it says MULTICHANNEL I can verify it is only coming out of 2 speakers.
Here's what I have noticed this past weekend as I've started doing this more. I am missing A LOT of bass information if I listen to these tracks in a 2.1 set up. Sounds fine when I do straight 2-channel. But once I add the sub which should send any info below 80hz to it, I lose my low end. It is easily heard and unacceptable to me.
In seems like the PS3 understands that I want to remove that below 80hz but does not send that info properly to the subwoofer.
Unless I can find a workaround, firmware update, are some setting I've screwed up I will be sticking with CDs. I really want to set up a media server and it works perfectly other than this issue.
Anyone else having this issue? Anyone willing to test it out?
Easiest test is to let the PS3 rip a CD to its own hard drive as AAC (I use the highest setting). Then play some tracks using a straight 2.0 setting on your receiver (try DIRECT). Then play the same track with a 2.1 setting (STEREO w/ sub ON). Play the AAC and CD version. Pick tracks that have nice low end. I notice is easily on some of my Medeski, Martin, and Wood stuff. It is also easily noticeable on the track JAMBI by Tool.
I'm sure you all know what in your collection to try it on.
I can tell you one thing in my set up. To my ears, I cannot hear the difference between the CD and an uncompressed file on my computer at all in pure 2.0 stereo mode. If I can figure out why it calls these files "Multichannel" and steals my bass, I will be tickled pink with this set up and a teryabite HDD!
