Sonix transcribes your AIFF file and creates closed captions that make your content accessible to everyone.
Apple's standard uncompressed audio format
The AIFF file format was developed by Apple and is based on the Electronic Arts .IFF file format. Standard CD audio AIFF files are sampled at 44.1KHz, are 16-bit, and have two channels for stereo sound. You’ll usually see the extension .AIFF from files that were saved by macOS machines. AIFF files are uncompressed and do have larger file sizes to accomodate the higher quality audio that are stored on them.
Lossless CD-quality audio, approximately 10MB per minute
