AAC is an audio file format known as Advanced Audio Coding. This format is used throughout Apple's line of digital devices such as the iPod, iPhone and iTunes. Sony's PlayStation 3 also uses the AAC format. Converting an AAC into a WMA, or a host of other formats (MP3 or WAV for example) is simply a matter of downloading a free converter from the web.
Choose your audio converter software (see "Resources"), which is available as "freeware" or for a fee. Freeware will do the most basic job, which is to convert your file from one specific format to another; in this case, AAC to WMA. Software for purchase can offer more robust options (CD burning capabilities) or more formats to choose from (AAC to MP3 or WAV or AC3, for example). Once you choose which software is best for you, download and install it onto your computer.
Use the file drop-down menu and choose "Open" or "Import files," or, in most cases, simply drag a file into the application directly (look for a "Files to Convert" window or "Imported Files" window)---after opening the program, as you will be required to import your AAC file or files into the converter.
Choose your output settings. In order to create the new WMA file, choose the quality and size of your new file. Knowing what you intend to do with your WMA file will help you decide these settings. For higher-quality playback, you will want a higher sample size and bit rate (CD quality audio is 16 Bits/44.1 kHz sample size.) For MP3 playback or use on the web, lower quality is acceptable and will create smaller files. Depending on the software you are using, these parameters and presets will be presented as a required step before the software can proceed with processing your AAC file.
Begin the conversion process by clicking "Convert" and the files are converted to the new WMA format.
