I tried it and immediately fell in love! It was so easy to use! After a couple conversions I bought the guys a cup of coffee. A couple more and decided this was too good to abuse! I joined! My life is so much easier!Tillie

AAC Audio Format AAC Converter
The AAC file is also known as an Advanced Audio Coding file and it is an audio format that uses lossy compression. It is the default file format for Apple’s iTunes. In its design it is like the MP3 file in that the data within it has been compressed but crucially the audio quality of the file is effected.
A human ear cannot tell the difference between a raw audio format and the audio contained in an AAC file. It is this reason why AAC is also becoming the defacto file format for audio for many other programs. Apple, for example, prefer the AAC format to the MP3 because even though both are compressed the quality of AAC is better and it’s file size is the same if not smaller than an MP3 file.
AAC is widely supported and can be opened by every device and program that can open an MP3 file.
MP4 Video Format MP4 Converter
An MP4, sometimes known as an MPEG4, is a multimedia file that is used to store video or audio data. MP4 files are typically smaller in size than other audio or video file types because MP4 files use a mix of compression technologies. Video and audio compression are usually handled by different codecs (audiovisual encoders). The video part is compressed with MPEG-4, a standard that was developed by Moving Picture Expert Group (MPEG), while the audio is typically compressed using AAC compression.
The explosion in popularity of the MP4 format is largely down to Apple and the iTunes Store, as it is the standard format for almost all of the media downloaded from the store. MP4 files are also typically seen when a video is downloaded from the internet.
MP4 files can normally be opened on your computer using Windows Media Player or QuickTime, and can be opened on mobile devices without the need to download any applications.
