What Are The Differences Between Multi-Channel Audio Formats

The new Dolby TrueHD and DTS-HD formats provide the digital audio signal at significantly higher bit-rates than that encoded on traditional DVDs. They are also the first real “lossless” audio technologies developed especially for new high-definition disk formats like Blu-ray and HD-DVD. The promise of these two new high-resolution digital audio formats is that they can deliver a true bit-for-bit recreation of the original studio recording. They both offer 8 discreet channels (7.1) of audio.
