Sonix transcribes your WEBA file and creates closed captions that make your content accessible to everyone.
WebM audio format for web applications
WEBA is an audio format that only contains audio extracted from WEBM video files. They are usually compressed using the OGG Vorbis compression codec for better transmission over the Internet. WEBM video files are the most common file format for HTML5 videos. Because WEBA files use the OGG Vorbis compression, they are supported in most media players.
