AMR Converter

AMR

AMR files are compressed audio files which are often used by cell phones. This files can contain voice recordings or voicebox messages for example. The format was developed by Ericsson.

AAC Converter

AAC

AAC is an audio file format that works similar to MP3 but compresses more than MP3. It significantly reduces the audio file size without losing the quality. To reduce the file size it uses the MPEG-4 standard to cut off the low frequency sounds that cannot be heard in a human’s ear.
