- 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.
- AVCHD (Advanced Video Coding High Definition) is a file format designed for recording and playing back high definition video. It is commonly used in digital camcorders and cameras for capturing HD footage. AVCHD leverages the MPEG-4 AVC/H.264 video compression codec, which efficiently reduces file sizes while preserving high-quality video resolution, and supports both Dolby AC-3 and linear PCM audio codecs for high-quality sound.
