Hi, i think it will work correct.when one thread use encode,the others wait for.
in java, i think we can do like this:
synchronized (Encode) {
        Encode.encode(short[] in, byte[] out);
}

In the doc of speex: it says the speex is not thread-safe.

I'll try to explain. I want to create dll with only one function "Encode" that will encode file to speex format. In my application I will use this function from 16 threads, if it will work correct?

 two thread send frames to only encoder at same time,two thread will use one buffer
.it will work wrong if not Handling thread synchronization.
 if not use same state, it need more memory, but no need to consider thread safe.

Well, please explain what you would expect from a "thread safe" codec
 when you encode two frames at a time from the same encoder.
