Wondering how to remove all metadata when exporting multiple wavs. (My app requires no metadata be present.) Audacity seems to be automatically adding the filename in the Title field, and a series of hex values in the Comments field.
Before you start exporting, open “File menu > Edit Metadata” and remove all of the metadata.
You can then disable the Metadata Editor from popping up during export, by deselecting the setting in “Edit > Preferences > Import / Export → Show Metadata Tags editor prior to export step”
