Mime type audio/aac

Format description

AAC files are audio files using Advanced Audio Coding compression. AAC is a lossy format, meaning the audio quality remains almost the same as the original source. The slight loss leads to the audio files taking up less space, which makes them ideal for music streaming or when bandwidth is limited. AAC is superior to MP3 for handling frequencies above 16 kHz. The encoding efficiency for transient and stationary signals is also better when compared to MP3.

This app is exactly what I asked for and is super easy to use. I am not a big time computer wizard so I need apps that do what they say do in a straightforward process. This app does just that! I love it and will continue to use it and will advise others of it as well. Good job to the owners/developers! And, sincere THANK YOU!

AMAZING! This is the perfect file converter! The first thing I used it for was to convert WMV files to MP4 and it worked flawlessly. I then realized it supports all kinds of formats and is basically unlimited. The UI is very user-friendly and super easy to navigate. Incredible app, MConverter!

Although there are occasional errors, I was very impressed with the efforts of the developers to receive feedback from users and to improve the inconveniences quickly. I will be using it more often in the future.
