On GrapheneOS AMR files are not supported and detected

[Mattrazol]

Describe the bug
If on GrapheneOS in the voice recording I select AMR-WB as the "Audio output format" the files that are generated by the recording (files .amr) are not recognized by the app (even if they correctly match the regex) and therefore they are not displayed on the list of recordings (Home).

To Reproduce
Steps to reproduce the behavior:

1. Open the app
2. Select a folder containing recordings from GraoheneOS that are in .amr format
3. The home screen doesn't detect any of them

Expected behavior
The files should be displayed and be able to be reproduced just like AAC or other audio format file

Versions (please complete the following information):

• BCR-GUI version: 1.5.0
• Device: Google Pixel 7
• Android version: 14

BCR-GUI does not filter files by extension but on MIME type (returned by Android SAF - Storage Access Framework).

These are the MIME types currently supported:

bcr-gui/src/app/services/settings.service.ts

Line 120 in 0e47940

public readonly supportedTypes: string[] = [

.amr MIME type should be something like audio/amr.
Could you confirm it? (you could see it with a filemanager, details...)
Otherwise I could try to create one .amr file on my side...

[Mattrazol]

I've tried to look for the mime-type with a few file manager but I couldn't figure it out. But by looking online it seems like you might be right the mime type should be "audio/AMR" I would double check though because I didn't invest too much time into it

Here's a build that adds support for audio/amr MIME type files.

bcr-gui-1.5.0-release-with-amr-support.apk.zip

Please confirm that it both shows (after a refresh) and plays AMR files correctly.

NOTE: it has the same 1.5.0 version of the latest official version...

[Mattrazol]

Yes it works perfectly!
Thank you so much!

Great, thanks for your feedback.
Will merge the change to dev branch, so you'll find it in next release.
Feel free to use this build since then.
