High latency with low level api on iOS

FMOD Studio
1

I’m using fmod studio to play sound on iOS Platform. I want to play the sound when i click the screen, but the sound didn’t play immediately, got a 170ms latency. The feeling is bad…

I’m using fmod low level api to play the sound with OGG files. but the latency exists even i playback the wav files…
How to reduce the latency.

You can use System::setDSPBufferSize to reduce the size of the mixer buffer, and System::setSoftwareFormat to increase the sample rate.
