The title says it all i guess. I converted my MP3 files to AAC but they still won't play. Can someone help me?

what program did you use to convert them?
what extension (*.blahblahblah) were they given after conversion?
will the files play on your computer? from the SD card itself?
did you properly dismount the volume/stop the removable device before disconnecting it from your computer?

I used a trial version of Xilosoft Audio Converter

It comes up as .aac

The AAC files work perfectly on the Computer when played through Itunes

Yes, i did.

Looks like that might be the problem. Here's what the manual says about playable file formats for DSi Sound:
AAC files with .m4a, mp4, or .3gp filename extensions
Bitrate: 16 kbps to 320 kbps
Sampling rate: 32 kHz to 48 kHz

Try using iTunes to convert your files (highlight files, right-click, then 'create AAC version' -- you can also rip CDs straight into AAC format via Preferences or Options IIRC, and you can set your default bitrates there too); it saves them as .m4a, and they play just fine on my DSi. :3

Ok. i'll try that. Just need to load everything up on my computer first.

It's all working now. Thanks theblackdragon

no prob, enjoy. :3

I will

I'm getting a new problem now. When trying to copy to the SD card, it won't let me. It says i need to remove write protection. How do i do that?

take out the SD card. on the side should be a teeny tiny little plastic tab that moves... it's like a 3.5" floppy, where you move the little tab to write protect it.

Working once more. Thanks again for the help

gosh the music player is better than a ipod XD

I'm getting the same problem kinda. I have Xilisoft as well and its on .aac files with .m4a extension and the bitrate is at 224Kb/s. It shows up on the dsi player but doesn't play. I'm going to try other bitrates and try that out.

Why all the conversion? Is something wrong with MP3? I won't update my Wii photo channel because I don't want to lose MP3 support, even though I never use it.

Fixed it, I just got iTunes.

There's nothing seriously wrong with MP3. It's just that companies are starting to use AAC a lot more, like Nintendo, Sony and, in particular, Apple. I think it's because AAC Was designed to be a successor to MP3, and is more advanced in several different ways over MP3, although not completely. Still, the advantages it does have is why i think Nintendo dropped MP3 support for the Photo channel and the DSi for AAC.

Thanks Terranigma, that helps. I'll spend some time on wiki today to see if there is more to learn.
