Convert MP3 to AAC
Convert your MP3 files to AAC online
MP3 (more specifically, MPEG-1/2/2.5 Layer 3; but not MPEG-3)
A standardized file for storing audio information. Supported by virtually all music players and playable on almost all mobile devices. When the audio data is compressed, the sound quality decreases, albeit insignificantly. The compression process erases the frequency that is imperceivable to the human ear. This format allows you to save storage space. You can store and send the audio files after compression. The MP3 format was developed by the German company Fraunhofer IIS. The user can adjust the compression ratio and the audio file quality.
Advanced Audio Coding (AAC)
This format stands for advanced audio encoding. Created as an alternative to mp3, it allows for compressing files at bitrates identical to mp3, obtaining high-quality sound. Files of the AAC format contain many sampling frequencies. Advanced Audio Coding includes 48 channels. This type of encoding is more efficient and includes a larger number of filters. Files of the Advanced Audio Coding format cut off the frequencies which the human hearing cannot perceive. This results in a reduction of the original file size.
