speex JNI 인코딩 디코드 오디오가 잡음이되었습니다

Question

Android IOS에서 wav 파일의 인코딩/디코딩을하고 있습니다.

나는 speex로 인코딩 된 파일을 디코딩 한 후 파일을 재생할 때 완전히 잡음이되고 말 내용이 없습니다.

여기에 대한 인코딩/디코딩 코드가 있습니다.

    return ret; 
}

    (*env)->ReleaseShortArrayElements(env, returnVal, outputArrayElements,JNI_ABORT); 
    (*env)->ReleaseByteArrayElements(env, in, arrayElements, 0); 

    return returnVal; 
} 

아무도 도와 드릴까요,이 문제를 해결할 수 있습니까? 감사합니다 & 안부.
