Issue #655 resolved
IJabz repo owner created an issue

Issue writing to Wav file because WavListChunk readChunk() returning false because conatins a tso2 field which is invalid since for LIST chunk identifiers should only be Alphabetical not Numerical. This causes outer loop to stop processing chunks and hence prevents reading data chunk if LIST chunk is at start of file, this then causesWavChunkSummary.isOnlyMetadataTagsAfterStartingMetadataTag() to incorectly return true and allows deleteExistingMetadataTagsToEndOfFile() to be run incorrectly
