First I'd read http://lifehacker.com/5879232/the-best-voice-recording-app-for-iphone which notes it's built in. HOWEVER with the headset attached the audio out is the headset so I will have to detach that before I get output from the speaker.
I am trying to record audio by Bluetooth headset mic and play by device speaker. I have seen few post regrading the same but still i am not getting is this possible or not ? and if possible then how to do it? if someone have any idea please inform me.
