Found this...if it works it might be a good thing to have in case one of these companies goes
belly up...

Extreme Sampel Converter - 39 Euro

Doesn't cover all formats, but most...
Obviously not perfect....

Here's the SOS review...which is a good review...

I don't think the software hasn't been updated in a few years & the article is from 2010. It also doesn't convert all libs correctly. ( VSL for one)

I bought SampleLord when Gigastudio was discontinued & it worked well although I no longer use it.
It came in handy after that Tascam disaster.

I thought it looked outdated...

I have it and can confirm it hasn't been updated in a long time.
 
Obviously results will vary depending on complexity and input/output formats, but it has worked reasonably well for me if you need such a thing.
