The Dolby vs DTS debate is a classic insoluble debate in home theater forums. The two audio codecs, Dolby Digital and DTS, are compared and users argue that one or the other 'sounds' or 'is' inherently better. Consensus is rarely reached. This is a home theater forum equivalent subject for Godwin's law.
For 6-channel surround sound, Dolby Digital bitrates generally range from 320 kbit/s to 480 kbit/s while DTS bitrates range from 768 kbit/s to 1.5 Mbit/s.
