- Description
- Compressed audio file similar to an .MP3 file, but offers several performance improvements; examples include a higher coding efficiency for both stationary and transient signals, a simpler filterbank, and better handling of frequencies above 16 kHz; maintains quality nearly indistinguishable from the original audio source.
- An ASF file is a media file stored in the Advanced Systems Format (ASF), a proprietary video and audio container format. It contains audio and video data and optional metadata, such as title, author, and copyright bibliographic data. ASF files are developed by Microsoft primarily for streaming media.
