Description

WebM is a relatively recent video file format for storing high-quality, highly compressed videos with very little quality loss. Because it is also royalty-free, it is frequently used on the web for HTML5 video playback. Its container is based on a Matroska (MKV) profile. It used the VP8 and VP9 technologies for video, and Vorbis and Opus for audio.

Mime type audio/aac

Description

AAC files are audio files using Advanced Audio Coding compression. AAC is a lossy format, meaning the audio quality remains almost the same as the original source. The slight loss leads to the audio files taking up less space, which makes them ideal for music streaming or when bandwidth is limited. AAC is superior to MP3 for handling frequencies above 16 kHz. The encoding efficiency for transient and stationary signals is also better when compared to MP3.
