Hi guys, I’ve read around that ima4 is supported by apple iOS devices. I created a bunch of ima4 sounds wrapped in AIF files using afconvert and on adding them to Unity I get the error
The file ‘Assets/SoundsConverted/Weapons/electrical_burst_01.aif’ does not contain a supported ‘aif’ format (Unsupported file or audio format. )
UnityEditorInternal.InternalEditorUtility:ProjectWindowDrag(HierarchyProperty, Boolean)
UnityEditor.DockArea:OnGUI()
are there any plans to support ima4 format in the future as it gives 4:1 compression with (as far as I’m aware) good quality and not too much cpu use.
Thanks
AIF / M4A support was actually cut in U3, you will need to use mp3
Also, their cpu use is just as ugly as for any compressed file format as the hw decodes a single file at a time of these formats, independent of the format used actually
M4A in my game resulted in a performance boost. It was faster than using Wav for some odd reason.
wav is uncompressed, m4a, aif, mp3 are compressed.
with a single one, it will naturally be faster, not much odd there, cause it will use the hw decoder.
but with more than one at a time it will go to software fallback and then it will start to suffer at least if its not an ipad / iphone 4 where the cpu can take the hit of 2, perhaps 3 compressed audio
