Hello, I would like to build an application which just echoes back the input given by the user. It simply talks back what is being recorded but at the same time. (out put the recording as soon as it is got). I have tried to look into the posts but there was no solution. I am using audiosessions and tried to follow this link http://blog.evandavey.com/2010/04/how-to-iphone-sdk-play-and-record-audio-concurrently.html/comment-page-1#comment-1737 But doing so didnt give any output on the speaker. Can someone please help me how to do it
