dbPoweramp is probably the program you want to use.
There's an optional paid plug in available but the free version is quite adept at changing beween formats.
My preference is Media Convert.
It is 100% free and completely web-based. Nothing to download.
I think you can have a try nidesoft video converter which could convert video and audio files between all popular formats such as convert AVI to MP4, MP3 to WAV, WMV to MPEG, MOV to AAC, etc.
Use Windows Movie Maker
Download Free software AV Media Player morpher to convert audio from one format to another and burn it into CD as well.Here is a free audio converter ( freedvdripper.net/free-audio-converter.html) can help you convert audio to mp3/wav, and then you can use iTunes or windows media player to burn the music to CD to play in your home music system.
First you need to Publish/Finish the Audio project in Windows Movie Maker. The finished product when exported from the program is .wma. Then you will have to convert the .wma audio into .mp3 format using an audio converter.
You cannot convert a Windows Movie Maker file into any other format. The only way to change the format is to Publish/Finish the project, which exports (mixes-down) audio/video properties into Standard viewing format. Once that is done, you can convert the file into whatever format you wish.
You do not have any other audio publishing options other than .wma if you are editing it in Windows Movie Maker. My suggestion is... edit the audio in Windows Movie Maker; publish/finish it in .wma format; then convert it to .mp3 using an Audio Conversion program.
To change your Windows Movie Maker audio file name extension (format) to .wma all you need to do is Publish/Finishit.Published video is exported in .wmv format, while audio is mixed-down into .wma format.Simple. Publish/Finish the project audio.
on many koz players on your computer you can transfer them to an audio CD... once on the audio CD you can then transfer them back to your computer by simply using windows media player... and they will come out in an mp3 format. little tedious but it works
One can convert audio and video to MP3 format by using conversion software. One do this with the 'Online-Convert' website or one can download an audio converter from 'CNET'.
