# Media file not playing

Do you want to add a sound file to a call, but the file does not play?

When you add a sound file, the URL of the media file to play should be a WAV file (8 kHz, 16 bit).

If your audio file is in a format different than WAV, for example, MP3, WMA, OGG, AAC, FLAC, you can use an [online WAV converter](https://audio.online-convert.com/convert-to-wav) to turn your file into WAV format. Don't worry about the specificities (8 kHz, 16 bit), once you convert the file it will automatically comply with those.

Please also make sure that the file is publicly hosted.
