Hello,
Here is an issue I encountered recently. Does anybody have feedback on this?
Issue encountered
- AVAudioFile
- throws when opening WAV files and MPEG-DASH files with .mp3 extension,
- works fine with many other tested combinations of formats and extension (for example, an AIFF file with .mp3 extension is read by AVAudioFile without error).
- The Music app, AVAudioFile and ExtAudioFile all fail on the same files.
- However, previewing an audio file in Finder (select the file and hit the space bar) works regardless of the file extension.
Why do I consider this an issue?
- AVAudioFile seems to rely on extension sometimes but not always to guess the audio format of the file, which leads to unexpected errors.
- I would expect AVAudioFile to deal properly with wrong extensions for all supported audio formats.
- ⚠️ This behaviour can cause real trouble in iOS and macOS applications using audio files coming from the user, which often have unreliable extensions.
I published some code to easily reproduce the issue:

Thank you everybody, have a great day 😎
