Which order of audio formats do you suggest to make code run fast cross browsers?

Answer 1

I don't believe the order would impact the processing time but you also have to consider the experience for example modern browsers will support MP4,MP3,and avi files but some may not support Ogg files. But if your highest quality source was in Ogg and you wanted to offer the highest level of quality first then you would but the Ogg source first but if you want to provide the highest level of compatibility you might offer MP3 or MP4
