AIFF and WebM explained
What is a AIFF file?
AIFF is an uncompressed, lossless audio format developed by Apple. Like WAV, it stores studio quality sound in large files and is common in professional audio on Mac.
What is a WebM file?
WebM is an open video format designed for the web. It offers efficient compression and is natively supported by modern browsers, which makes it ideal for HTML5 video.
