Sonix transcribes your AIF file and creates closed captions that make your content accessible to everyone.
Uncompressed Apple audio format with CD-quality sound
The .AIF file format was developed by Apple in 1988 and is based on the IFF (Interchange file format). Unlike MP3 files, .AIF files are not compressed. Thus, they are larger than MP3 files and have considerably higher quality audio stored. They are usually 10MB for ever minute of audio. Usually, Windows software will create .AIF files.
Lossless format - maximum audio quality preserved
