Samples that won't import (and best practices)

Howdy,
Fairly new to the Deluge (and having a blast!). Quick sample-related question...
I put a bunch of new WAV samples onto my SDCARD and when I went to load them into a Kit slot, I got "Unsupported" for most of the files.
So, I searched the forum and found this thread where it said that the Deluge should support:
"Stereo and mono. Native format = 44kHz 24bit, but will play anything up to 96kHz 32bit"
I opened the samples in Audacity and they appear to be "44100Hz and 32-bit float." If I export them as 24-bit and put them back on the Deluge, they load just fine.
Happy to do that (thought it's a LOT of samples to convert!), but just curious if there's an obvious reason why these won't import as-is? Attaching a few here for reference: https://drive.google.com/drive/folders/1sz_zaZ9poz-sDK6-LrRsxtQnsxCtn_YQ?usp=sharing
Many thanks in advance,
Phillip.

I downloaded your samples, but they are 24 bit:
In Audacity, the bit-depth shown to left of the waveform is the resolution the file is imported at according to your Quality Preferences, and not the actual bit depth of the file.

Yeah it looks like those files are 44.1khz/24bit. No reason they shouldnβt work that I can tell.
You should send them to @rohan to have a look I think.
Send a mail to rohan@synthstrom.com with your samples, he should be able to tell what the problem is, for future reference and possible bugfixing

Thanks everyone. I'll send them over to Rohan to see what's up. π
Thanks for this info @volsteh, I didn't realize that! π€¦ββοΈ
NP, afaik there is no way to check a file bit depth in Audacity.

There is an issue with the specific header info of 24-bit WAV -- there is a "legacy" Microsoft PCM standard and an "extensible" PCM format which Microsoft added some years ago... The Deluge (and some other HW and SW!!) doesn't support the extensible format.
The best way to check is use https://www.metadata2go.com/ and compare with the following examples:
Supported PCM WAV format:
Unsupported PCM WAV format:
It's a bit odd that the audio "payload" data is exactly the same, but the headers make the difference between some SW/HW being able to read it or not. I use Goldwave audio editor which allows you to choose "obsolete" and batch process many files in one go. I'm assuming Audacity only supports "legacy" PCM which works everywhere.
I keep meaning to raise this with Synthstrom but I have an easy workaround... maybe Ian or Rohan will see this and comment
Great info! Thanks for figuring this out. Im gonna tag @Ian_Jorgensen and @rohan, this may help them out.

@volsteh - you're welcome! It's not just Deluge, we also found the issue in Reaktor and have heard it's an issue in Energy XT. Frankly, it's Microsoft's fault for messing with the standard
@rohan should be interested indeed!
