A high-tier test disc allows users to directly compare the two technologies using identical acoustic master files. Dolby Digital (AC-3) DTS (Digital Theater Systems) Typical DVD Bitrate 384 kbps to 448 kbps 768 kbps to 1536 kbps Compression Method Highly efficient, lossy psychoacoustic modeling Less compressed, higher data overhead Perceived Character Often praised for wide dynamic range and clear dialogue.
