WAV: Where to fetch Rating from?

Post by Thijmen » 11 Aug 2020 22:33

Hi,

I have a question. In the TAG editor, I can save the rating of the file. But where does this get's stored? In the file? I don't see it in the pfmd file.

It is stored by default inside the standard TAG of the audio file. For wav files this is the RIFF list info chunk.

You would need to explicitly enable saving meta data to the separat .pfmd file. Which I would only recommend in very certain cases, but you should never mix both option, saving meta data to the audio file and storing them in the pfmd file.

I see. When I inspect the file before and after saving the RATING in PF, I see that the 'sharpness' gets changed. Do you store it in 'sharpness' in RIFF?

Thanks Bernd! However, that post does not make it clear it is the SHARPNESS field... or am I misinterpertating it?

A RIFF chunk always uses a 4-digit magic/identifier.
As described in the link given, ProppFrexx uses RIFF: ISHP for the Rating.

As such, my answer above was Yes, it is the Sharpness field known from other RIFF formats, eg. AVI.
