Free AAC to MP3 Converter

Free!!

AAC - Stands for Advanced Audio Coding. It's a type of digital audio file and has been promoted as the successor of mp3. AAC generally offers higher-quality sound than an MP3 while using the same amount of disk space. But sometimes your player may not support the protected AAC files. And you would like to convert aac file to other common format.

Now you can convert aac file to mp3 with the free AAC to MP3 Converter, which also allows you to convert AAC to AIFF, FLAC, WAV, AC3, OGG, and WMA. In addition, the following formats are supported for converting to AAC: MP3, AC3, WAV, AC3, APE, OGG, RA, FLAC, etc. You can convert your AAC files to various audio formats with the Free AAC Converter.

This freeware for converting AAC audio to MP3 audio and convert MP3 audio to AAC audio also, can play and decode AAC audio files and convert between AAC audio and MP3 audio format. It is very useful audio tool. At the best, it is absolutely FREE software.

What is AAC format?

AAC stands for advanced audio coding and is the logical successor to MP3 (ISO/MPEG Audio Layer-3) for audio coding at medium to high bit rates.

How AAC Works

Like MP3, AAC is a lossy format, meaning that in order to compress CD-quality audio files into smaller files suitable for transmission over the Internet, some data that will not impact the listening experience of the file is removed. As a result of the compression, though, AAC files do not sound identical to CD-quality files.

Like MP3s, the quality of an AAC file is measured based on its bit rate, rendered as kbps. Also like MP3, common bit rates for AAC files include 128 kbps, 192 kbps, and 256 kbps.

AAC vs MP3

The psycho-acoustic encoding principle used by AAC is similar to that used by MP3, but AAC uses an improved implementation of the psycho-acoustic encoding model and more efficient analysis and encoding, and will therefore yield better sound quality than MP3 at the same bitrate.

AAC does have a few other quantifiable advantages over MP3. Most significantly it is capable of storing up to 48 channels of synchronous audio, compared to MP3's 2 channels. This makes it ideal for compressing surround sound mixes and other multi-channel material. A combined bitrate of 320kbps is sometimes cited as a good 'rule of thumb' for transparent 5.1 surround AAC compression. The potential of AAC for multi-channel support within the MP4 container is however well beyond 5.1 or indeed any current standard surround sound format, and therefore offers significant future scalability.

Even though AAC is supposed to be improved and developed audio format in comparison with MP3 it should be admitted that from time to time one needs MP3 more often than AAC. It happens quite often mainly because MP3 audio format is supposed to be the most popular encoding format and it is still widespread. And in the case one of your players doesn’t support AAC you have to convert AAC format to MP3 with the help of AAC to MP3 Converter that you can easily download from the Internet and install into your computer.
