I read the data from the Wav file and then use Fmod\_createsound to create the sound effect. I found that this method takes a lot of time, about 0.1s. Can someone tell me why? How can i avoid this？

code：  
FMOD\_CREATESOUNDEXINFO exinfo = { 0 };  
exinfo.cbsize = sizeof(exinfo);  
exinfo.length = (unsigned int)pDataBuff-\>size();

res = FMOD\_System\_CreateSound(FMODSystem,  
(const char \*)(pDataBuff-\>getPtr()),FMOD\_VIRTUAL\_PLAYFROMSTART | FMOD\_3D | FMOD\_OPENMEMORY, &exinfo, &pFMODSound);

Different file types take different amounts of time to load, you could also try using the `FMOD_NONBLOCKING` flag.
