Hello,

I know mp3 has royalty issue.

If I build an app with mp3 sound files.

When I publish this app (free app) to google play and apple store.

  1. Is it possible to be rejected because of mp3? if not, what’s the consequence? :o

  2. Do modern android devices support m4a?

  3. Any other suggestion other than m4a+ogg?

Thanks for reading/reply.

Hi @hydralisk_mk2,

  1. I can’t predict whether you’ll be “rejected” on this, but you could face royalty issues. Best to avoid it.

  2. No, you’ll need to use either .wav or .ogg for Android.

Please see the Audio guide for formats and other details:

Thanks,

Thanks for reply.

If I was correct, you only have to be licensed if you are encoding/decoding mp3.

But I only use legal mp3 files as sound effect, it’s not clear of infringement?

And I see a lot of apps uses mp3 as audio files directly, not downloaded by user.

Hi @hydralisk_mk2,

If you have mp3 files that are clearly not going to infringe on any royalty issues, then go ahead and use them. :slight_smile:
