it seems that Juce is copying the ISRC code to the RIFF::INFO metadata with chunk Id “ISRC” when writing the ISRC code to the axml chunk in a wav file. This is not right. The chunk Id ISRC in RIFF::INFO is NOT the ISRC code, but stands for the source of the file. There is no chunk Id for the ISRC code as far as I know.
