Sonix transcribes your AIFF file and exports it as WebVTT captions perfect for HTML5 video and web platforms.
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.

Wow. SPEED. Nice format, easy to read, liked the time stamps and speaker notification. Not a lot of formatting I had to strip before using. Simple.
I need to produce very accurate transcripts and the initial transcripts Sonix produces are much better than competitors (I've used many others).
I am LOVING Sonix! The price, accuracy, create your own library, check marks when something is completed. I am so glad I found the service.
I was amazed that Sonix picked up words that I couldn't even understand.
My first trial was a video interview with a woman with an Eastern European accent, and I thought there was no way your system would render a good transcription—but it was amazingly accurate...
I loved how accurate you are even in Dutch!
This technology managed to shock me! It saved me so much time and effort!
The speech to text was fast and very accurate.
