Error - Wave tag is not supported

I'm trying to analyze some audio files for S/N, distortion, etc. These are voice .wav files. When trying to open one, I get the error of "Wave tag is not supported." The format on these is ADPCM. Any idea why I can't get these to load? Thanks

Please send one of these files to support (at) afmg.eu, and we will have a look. What application was used to record these files?

Unfortunately, I'm not able to send the file due to confidential content of the audio. Various organizations dictate via telephone into our datacenter and I don't have information on what specific device/application is used for each. We have employees then transcribe text from those dictated voice files.

Subjectively, it's clear that some audio quality is superior to others. However, I need an objective metric to apply to these in order to evaluation transcriptionist productivity based on the audio quality. Something like audio quality X = transcriptionist productivity Y. I will eventually need to run/analyze thousands of files to gain these metrics over a long period.

I was hoping to use EASERA to accomplish this. Does this sound practical based on your application's capability (provided we can work through the error I receive for these files)?

I am not quite clear where the recording happens, at your data center, or at the various organizations that use the data center. In any case, I skipped over the part where you said the format is Adaptive, but I suspect we don't support that codec, which is why the tag is not supported.

Now that I understand what you are trying to do, if you were able to create a PCM wave file by decoding the files you have, EASERA would be able to do some of the analysis you need, but I am not sure it can give you all that you need to get to the quality metric you desire.
