The maximum uncompressed bit rates for a movie soundtrack are approximately:

48,000(samples per second) x 16(bits per sample) x 6(channels) = 4.6Mbps
48,000(samples per second) x 20(bits per sample) x 6(channels) = 5.8Mbps
48,000(samples per second) x 24(bits per sample) x 6(channels) = 6.9Mbps
48,000(samples per second) x 16(bits per sample) x 8(channels) = 6.1Mbps
48,000(samples per second) x 20(bits per sample) x 8(channels) = 7.7Mbps
48,000(samples per second) x 24(bits per sample) x 8(channels) = 9.2Mbps

Dolby TrueHD and DTS HD MA can go up to
96,000(samples per second) x 24(bits per sample) x 8(channels) = 18.4Mbps

Remember that since both CODECs use variable bit rates, we cannot calculate the average bit rate of a typical soundtrack. In addition, Dolby TrueHD and DTS MA use different compression algorithms and on the average use less than the maximum numbers.

Theoretically, LPCM, Dolby TrueHD, and DTS Master Audio should sound the same if they are encoded at the same number of bits and sampling frequency (16 bits, 48 KHz for example). Any difference that you may hear are due to channel volume differences.

Decoded Dolby TrueHD = Decoded DTS HD MA = Uncompressed LPCM

Please stop the nonsense.

Jeez....how many times must have have these nonsense polls and threads about which audio codec is better????

They're all the same, thread closed
