I really want a better compressed audio support to XNA 3.0 ( XACT ), because this will help everybody that want to use songs in game. 
 
If some professional involved on XNA 3.0 development is reading this post, PLEASE take a look at this problem because, the XACT compressed auldio support is poor and don't even support WMA audio files, that is a shame!  
 
Please dont ignore this post, if this problem will be solved it will help us a lot indeed!

#1 Your post was totally off topic for the thread you posted in

#2 The forums are not the right place to post feature requests - they can get missed and there is no tracking. We have an FAQ on how to submit feature requests and bugs http://forums.xna.com/thread/1864.aspx

#3 "please don't ignore this post" and "the XACT compressed auldio support is poor and don't even support WMA audio files" are not good ways of justifying features to the XNA team. They get 10x the number of requests than they can fit into a release so you need to explain WHY you need WMA, Why the current PCM compression is not good enough (hard drive space is insanely cheap on PCs these days)... The more professional your request and the better the justification the better chance you will see your features.

#4 Check out the XNA 3.0 FAQ http://forums.xna.com/thread/48067.aspx - maybe the feature you want has already been announced somewhat.

#5 Maybe community members have already solved your problem http://bxnaa.spaces.live.com/blog/cns!85007EAD17D3E592!172.entry (PC only of course)

Posting in the forum is not a good way to request features. Thankfully there is a FAQ which provides information for requesting features in the official way: http://forums.xna.com/thread/1864.aspx. Do that and post back the link to your feedback page so others can vote on it. That's how you raise issues with the team.

The community cannot solve this problem without first getting access to writing raw audio buffers. Then you could use a user-level WMA or OGG or MP3 decoder, and all would be fine.

XAudio2 supports WMA compression, but as it's still in the throes of beta, and XACT hasn't yet been updated to sit on top of it, it can't be used for release titles yet. Hopefully, they'll update to whatever the latest and greatest is when they release 3.0.

Well, I was able to add XACT3 support with WMA compression for Windows base games without any trouble (only XAP compiling can be considered a bit weak right now) and the DXSDK March 2008 does not mention any betaness of WMA support or XACT3/XAudio2 - both are actually RTM now.

XAudio2 in RTM is great -- when I searched for XAudio2 on MSDN, I still got the beta documentation. Thus, there's plenty of opportunity for our friends on the XNA team to add, update, and test. If it came out of beta in, say, September, I think the chances would be less ;-)

Oops I didn't know my post was moved to this Topic, however I am glad to receive the attention of you. 
 
I did that request because I want to make a game with more than 8 songs, and I don't want to spend 50% of the memory limit of the game with the songs, I just want to make a game with good graphics, beautiful stages, high def sprites and a loud and clear sound. 
This is what I request a WMA compressed audio support, using WMA I can put 8 whole songs (192 kbps quality), and waste no more than 24 MB :-) 
 
I will also take a look at the options you showed me above, maybe I'll find a good way to manage the music files. 
 
Thanks for all.

On the Xbox, you have XMA, which is similar to WMA in compression quality and size. On the PC, right now, you can only use 4:1 ADPCM compression, which isn't terribly great, but it's only a factor 2-3 away from WMA. I e, on the PC, you can currently make a game with lots of music, and you'll just have to require a bigger download. That's "not so bad" compared to the Xbox, because there is no 150 MB size limit on the PC, as there is on the Xbox.

However, there are lots of other nice features in XACT 3, so I still hope it makes it into XNA/FW 3.0.

But just because the XNA FX 3.0 might use XACT3 doesn't even remotely mean we get access to the lots of nice fatures; just compare the nice features in XACT(2) and what is available in of them in the XNA FX :]
