how to make *.aac?

this is my first post in this forum, so i am a little nervous 

i have a Nokia 3300 mobile phone, and, as you know, it has a digital music player in it, which can support MP3 & AAC.

AAC sounds better than MP3 because of its Quality/Size, but is there a software that can convert other format files (such as mp3, wma,...) to *.aac (not mp4, not mpa) directly?

i am freshman, so maybe this question is so simple that you will laugh at me, but i really need help. 

thanks!
the earth is becoming worse, who can save it?

Be aware that "transcoding", as it's called, from one lossy format (like MP3 or WMA) to another (like AAC) will NOT improve sound quality of the original file.  In fact, it may make it worse.

When a song is encoded with psychoacoustic compression (in any of the formats you mentioned), it throws away part of the audio data, the part you hopefully would never hear anyway.

But upon transcoding to ANOTHER lossy format, a different psychoacoustic model throws away a DIFFERENT part of the audio...and cannot replace what was thrown away the first time around.

But, assuming you're still OK doing this after my explanation, dBpowerAMP Music Converter can transcode from and to many formats, including the ones you mention.  Download the music converter, then go to the Codec Central page to grab the codecs you need.  It comes standard with an MP3 codec, but you'll need to download some of the others you may want, including AAC.

Hope this helps.

*.mp4 is only a container of aac string, so I think there must be a simple and lossless converter to do that: *.mp4 ->*.aac
No pain no gain!
