how can I play a mp3 file in unity in the uwp
I have some external mp3 files. And in unity editor I can use NAudio to change mp3 to wav, or I can use libmpg123-0 to get the byte data. But in uwp, I encountered some problems:
NAudio.dll can't compile, libmpg123-0 can't be found.
My purpose is to change a text to speech in unity, and it should work in hololens. Now I get the mp3 stream, but I can't find a way to play it.
Who can help me?

OK, finally I use the "mp3sharp" to solve the problem in hololens. I delete many codes which can't use in the UWP, and modify some codes to make it adapt to my need.

You can play MP3 files in unity. Or why do you feel the need to convert?

Unity don't support mp3 file in windows. I use WWW to get a mp3 in my Hard disk and play it, but the unity console show "not support mp3".
Maybe try ogg?

hi @t_xliang ,
I have a raw audio data(audio/mpeg) which is generated at runtime(i.e it's a REST API response). Do you know how can I play the audio in AudioSource. I looked up Mp3Sharp but didn't understand how to use it in my case.
I have tried various other approaches as follows:
1. Used WWW
www = new WWW("file:///" + Path.Combine(Application.persistentDataPath, filename));
yield return www;
audioSource.clip = www.GetAudioClipCompressed(false, AudioType.MPEG));
2.
Use WavUtility class which reads the bytes from Wav file and then converts to float and creates an AudioClip
WavUtility Code: https://github.com/deadlyfingers/UnityWav
https://answers.unity.com/questions/737002/wav-byte-to-audioclip.html
3.
Holo-Academy 212 doesn’t help because it just records the user’s Audio through Microphone Manager script and playbacks the audio clip.
4.
Also, tried this approach https://forum.unity.com/threads/loading-audioclip-from-a-file-not-resource-after-www-audioclip-is-gone-unity-2017.490884/
But my wav file is generated at Persistent Data Path, so tried to provide that path also, but it didn’t work out.
