Sonix transcribes your OPUS file and exports it as a professional PDF document that you can share with colleagues and clients.
Modern audio codec optimized for voice and streaming
The OPUS file is an audio file format that was created for use in Voice over IP (VoIP), video conferencing, or in-game chat. Since the OPUS codec is primarily used in Internet streaming applications, it isn't common. However, is it a lossy audio format that uses both SILK (used by Skype) and CELT (from Xiph.Org) codecs and supports variable bit rates from 6 kb/s to 510 kb/s.
State-of-the-art codec for voice; excellent at low bitrates

I love the platform and its been a transcription godsend.

I have a 30-40 minute commute to work and like to dictate memos and other brief documents along the way–but I haven't had an easy way to get them transcribed...until now. Thanks Sonix!
I love how accurate the software is! The way you can play audio as you go through the text or click on any part of the text to hear the audio is amazing.
Thank you for all of your help with my dissertation!!! Ya'll rock!!
