Please add support for lossless PCM AIFF files: Audio Interchange File Format - Wikipedia
I saw this discussed elsewhere but I don’t think that user raised a feature request here: [CLOSED] [APP][5+] Symfonium: Music player and cast | XDA Forums
This is a relatively common format for lossless downloads from DJ-related music sites (e.g. beatport.com) and some hi-def audio sites (e.g. qobuz).
Other users will have audio files from these sources. Currently using Symfonium with Navidrome backend results in an error trying to play an AIFF file. I could enable transcoding on the server, but the configuration for that is quite broad and it would cause a few other file types to be transcoded unnecessarily for me.
Other application solutions:
I used to use RockerPlayer prior to discovering Symfonium, which had support.
Navidrome has support for indexing and serving aiff files: navidrome/mime_types.go at master · navidrome/navidrome · GitHub
