Help with verifying bit depth...

[new_media]

If I have a suspect FLAC file, what is the best way to verify true 24-bit vs. upcoded 16-bit?

 

Thanks.

Julf posted on how to do this recently:

Thanks for the link, and to Julf for the original post. Will check it out in the morning.

Bill,

 

Could I trouble you for a link to the FLAC binary for OSX?

 

Thanks again.

Thanks for the help wgscott and Julf.

 

FLAC returns 0 wasted bits on the file in question, so it's either legit or the distributor is a master of obfuscation, I guess.

Julf's method is a nice way of detecting 24-bit files that are 16-bit files padded with zeros. I wonder if there is software that could identify 16-bit files to which very low-level random noise has been added to make them look as 24-bit files. I am not an expert in signal processing but what I learned in maths suggests to me that it should be feasible to test if the low-level information is just noise or something else.

A question for others, does Sony's Sound Forge 6e software perform this bit check ?

It looks like a nice piece of software, but I don't see something that could include this feature in the specs.

I compiled it with fink and put the debian binary on my server. It sounds like you found a better way...

Thanks Bill.

 

My solution was to use my daughter's PC, but I would still like to have the binary for my Mac.
