Do most commercial BD movies today use 24-bit or 16-bit audio?

both.

The proper setting for sharpness is always0.
Also my Oppo BDP-103D is region free.
That makes me awesome.

No it's probably lie 80-90 percent 16 bit and then some 24 bit. There is also 20 bit.

Most titles are 16-bit 48khz. Recent titles and restorations are typically 24-bit 48khz. Some titles are 24-bit 96khz.

Are you sure about that? I've got 168 movies on BD, and 119 of them have 48kHz / 24-bit audio. I'll admit it's not a random sample, but still I doubt that my collection is that unrepresentative of the market as a whole...

There are 1473 24bit audio titles on Blu-ray according to Blu-rayStats.com and 657 with 16bit audio.

Also according to the stats page... only two titles are in 20bit audio.

My Dual 18" LLT subs 120dB down to 10hz

True but many of them are made from 16bit original Masters. So there is no dynamic range increase but it can lower quantization errors.

Also of interest is yesterdays (5/17) announcement by Dolby of their Advanced 96Khz Up-sampling for TrueHD.

Yeah, to bad most studios use DTS on Blu-ray.

Dolby kinda lost that race years ago.

Maybe this will help them or increase the chances they are included as an option.

Perhaps I should be more specific: Can lossless audio tracks like DTS-HD MA and Dolby TrueHD and Uncompressed PCM be 16-bit or are they always 24-bit?

What you get is what you get. All three audio formats are usually either 16 or 24-bit on Blu-Ray depending on the settings of the encoder and LPCM/DTS can be 20-bit in addition to 16 or 24.

is there any way to determine what bit depth a given BD has? my PS3 shows sampling rate but not bit depth

Set-top players often have the ability to show you what the specs are.

They can be either 16bit or 24bit. The "lossless" part is the just how the entire thing is packaged.

You can tell the bit depth if the soundtrack is LPCM by the fixed bitrate amount. If it's about 6.9 Megabits/sec then it's 24 bit/48 kHz. 4.6 if it's 16 bit/48 kHz.

Otherwise, you need analysis software.

Listen up, studios! Just say "NO" to DNR and EE!!
