Error after modifying pitch several times

[wlonglee]

I use Sonic.java
Sonic sonic = new Sonic(48000, 2);

public updatePitch(float p){
sonic.setPitch(p);
}

When I call ‘updatePitch’ multiple times,The program has stopped！I noticed that calling the ‘writeBytesToStream(byte[] inBuffer,
int numBytes)’ function didn't even get to the next step
