DTS 96/24... Is it "Lossy" or "Losless"?

[mitch57]

I've searched high and low and I can't seem to find anything that spells it out in plain english.

I know that .jpg files use "Lossy" compression. As do MP3s. I also know that DVD-A disks use MLP (Meridian Losless Packaging). But what form of compression does DTS 96/24 use? Can someone provide me with a link that actually says it's one or the other?

Thanks,

Mitch

DTS 96/24 is a lossy compression upgraded from the standard DTS compression technology(An Overview of DTS 96/24), however the upcoming DTS-HD looks like it will be a lossless compression.

I read this same link before I made this post. However, where in this link does it actually say that the algorithim that they use is "Lossy"? Did I miss it somewhere? Can you please direct me to a specific paragraph in the document that says that it uses the "Lossy" form of compression?

The reason I ask is that I have a friend who is convinced that DTS 96/24 uses "Lossless" compression. If it truly doesn't use "Lossless" compression then I want to make sure I have the facts to back it up.

Thanks for the post.

Thanks!

DTS has demonstrated Coherent Acoustics in 24-bit, 96 kHz

Taken from: DTS: BRIEF HISTORY AND TECHNICAL OVERVIEW

Coherent Acoustics coding
These objective and perceptual inefficiencies, inherent in linear PCM encoded audio, can be reduced by using a more flexible coding scheme which takes explicit account of the underlying characteristics of audio signals and human hearing.

Taken from: An Overview of the Coherent Acoustics Coding System

All the papers I've submitted explain the lossy Coherent Acoustics coding system that DTS uses to encode and compress its data. The simple fact is that all DTS and DD formats at the moment are lossy formats.

I doubt DTS will have in big bold letters on their website a statement like 'DTS & DTS 24/96 ARE BOTH LOSSY COMPRESSION' That would be political suicide and plain dumb.
The only way your going to convince your mate using DTS papers is if you give him those papers and let him read and understand technical workings of the DTS coding systems , Good luck

Unless someone else can find a DTS paper that has it spelled out, I think thats the only 'proof' you'll get out of DTS
