From Yahama,


"Yamaha employs sophisticated digital signal processing with exclusive algorithms to enable playback that improves the performance of compressed music formats, including MP3 and WMA. With the Compressed Music Enhancer, highs and especially lows are richer and smoother, bringing music back to life to be as close to the original as possible. "


Anyone have experience with this?


Do any other brands offer something similar?

Your quote (above) smacks of marketing hype.

Just about everyone offers this now, Penn. Denon even offers headphones with this application. It is called "music restorer"

Creative's Xfi soundcard has an adjustable "Crystalizer" function that worked great with internet radio and 128 kbs music files while I used that card on my gaming rig. I doubt that it restored streamed files back to something close to original like Yamaha is implying but I would agree that it added more "life" without any annoying side effects. In any event, I always enabled it for internet radio listening and would likely use the function now if it was available on my 2-channel music system.

This is correct. Onkyo also calls it "music restorer". IMO, it is a useless effort though. I have not had very good results.

Exactly my thoughts. I'm not sure how it could possibly be effective aside from doing some EQ-type sweetening.

lmao, Sorry about no link....I will find it. I was looking at a new Yahama product and I forget the model right now.


I was wondering how this could be done with compressed music. It would be nice if it worked well enough.


Im not sure why you would say "you" of all people
Im always curious about all things, more then you think

Thanks, I will look that up.

It is possible to do predictive interpolation, rather than averaging. Doing some pattern analysis one could predict what the missing section between samples or steps could have been like. Not accurate per say, but a reasonable facsimile of it. This could work for music or pictures as they are highly correlated. Maybe quite suitable for an audio file. Totally useless if the file was random in nature, like an encrypted file. Not that Yamaha is this sophisticated, I am just saying there is a viable technology that could make a reasonable high-fidelity sounding recovery form a lossey compression.

Lots of receivers has some kind of feature like this. I believe in my reading it's usually just some kind of EQ of some sort, sometimes adjustable in strength. Particularly very heavily compressed content can have the highs rolled off a lot, so it may just be a HF boost, etc.


Just try it our and see what you think. It's not actually "restoring" anything, just making it sound different and perhaps less bad perhaps depending on your point of view.


I've never really spent much time playing around with it because I listen to CDs and vinyl, not really relevant to me.

OtherSongs,


Here is the link

http://www.yamaha.com/yec/products/p...?CNTID=5036838


Im looking for something very slim like this Yahama to fit in a specific location. In the feature section it talked about the enhancer.


Your above ref only says this:


I also searched on "Compressed Music Enhancer" which gives 356 products, 10 FAQs, and 9 manuals. Titles of the FAQs and manuals didn't look like they explained anything, so I didn't go any further.


Looks to me like mostly marketing.


Buy one and post here about it.




Cheers

Yes, as I explained, a guessing game. Due to the structure of music being highly correlated, there is reasonably good probability that one could guess very well. Again, not saying this is what they are doing, just suggesting a possible technology. I would suspect it is more of what was suggested as some minor eq.

How do think digital processing works with matrixing to 7 or 9 channels?

Penngray, I think you should buy one and try it out. Just think of all the fun you could have. you could measure it, you could compare various mp3 bitrates, you could abx it, you could see if different speakers matter, then abx and measure it again. Hours and hours of fun
I assume you would have to make your own mp3's, so you could compare the software for that as well. If you don't like it you can probably return it. Do it.

Fun stuff....I just spent a week trying to get the right measurements of my new speaker design.


There is no way I would do this for MP3s, I will just enjoy my Ipod while Im building something new

If it is EQ, how would that not be consistently applied to all music played, compressed or not?

Onkyo calls this feature Music Optimizer. Here is what they have to say about it.


"The Music Optimizer function only works with PCM

digital audio input signals with a sampling rate below

48 kHz and analog audio input signals. The Music Optimizer

is disabled when the Pure Audio or Direct listening

mode is selected.
