<div id=":15a">Hello,<div><br></div><div>I am attempting to use Speex in an iPhone application and running into an issue.

<div><br></div><div>Next, I was able to record some audio and play it back. I then inserted a call to the speex preprocessor and am passing all of the audio buffers I receive from Audio Queue Services (the iPhone/Mac audio streaming API) into speex_preprocess_run. The problem though is that speex_preprocess_run is returning a 1 regardless of whether I am speaking into the microphone or not. There is this output in the log when debugging my program:</div>
