Reporting this in case not reported or other solution.  
Have Scaler 2 iPad and CAN select an .m4a audio file in file chooser for use in Audio Detection. However, in desktop Mac Scaler 3, not able to choose an .m4a format audio file with Audio Detection file chooser.

Thanks.

Hi @HoneyBearStudio, thanks for your post and apologies for the long gap in response.

`.m4a` files aren’t currently supported for Audio Detection in the desktop versions of Scaler 2 and 3.

Moving this to the feature requests section, and if there’s enough interest from other users we can look at adding support in a future update. Cheers.
