Do I have to check the various formats for audio/video?

I've found an audio mp3 sound for my zombie. It's an mp3 format. Now if I wanted to use the other available audio files (wav, m4a ogg) etc for backup purposes would these audio files(sounds) be already availble on the backup. Or would I have to check each audio file to see if those files have the same audio/sound as my original MP3? Hope this makes sense to anyone reading my question

If you only have an MP3 to begin with, you would have to convert that file into the various formats that you want to support.

MP3 is supported by about 99% of browsers. If you wish users of old versions of Opera to be able to hear your zombie then make OGG available. I suggest you use Audacity to convert your MP3 to OGG. These days I would not bother with any other audio file formats.

SamA74 thanks for sharing your advice with me. Much appreciated.

Archibald, Thanks for this valuable advice tip. I will look in Audacity as it’s a software that I am familiar with.
