Missing 'Sample Size' for lossy formats

[bengo]

I'm using Batch Converter to figure out which files use 24-bit and/or 96 kHz (as my car player has trouble I need to convert them to 16-bit and 48 kHz max).

For FLAC this works perfectly, but for .m4a (iTunes) and .mp3 (purchased from Amazon) nothing is shown. Perhaps these formats do not support 24-bit? I'm pretty sure in my case they are all 16-bit. Still, it would be nice to show this explicitly rather than leave the box blank.

Mr Spoon..?

mp3 or m4a (aac) do not have a bit depth, the player can decode to 16 or 24 bit.

Thanks for explaining!
