Audio & Images Performance on different platforms

Hello,

Currently I’m using mp3 for audio. Let’s suppose I want to more performance on apple hardware, Should i switch to another format.

Will there be difference in performance?

Same goes for images I currently use png format mostly RGBA8888 and RGBA4444 (nearest neighbour) are there any better solution performance wise for apple hardware or is this fine?

Thanks

@AndreasLoew might be the best resource for the png questions.

I’ve never thought so much about performance of audio formats on specific platforms. Let’s see what we can figure out.

@bilalmirza about image, i think you can use compressed format that supported on the platform. For example, pvr on iOS, ETC1 on Android. As ETC1 doesn’t have alpha channel, so you should use another file for alpha channel, there is examples in cpp-tests.

About audio format, i am not sure, but i know ogg is good on Android.
