Hi Friend,

How can we amplify the audio we record?

I have tried to use this but failed. What i am actually trying to do is to playback the same what is being recorded simultaneously. No output is got at the speaker. I have tried with all the remaining SDKs but no result

Ed:

Apple doesnt wants you to record any audio due to copy rights, but TuneIn Radio app has such feature. So, dunno the real thing.

/dev/null PROBLEM!

If you analize the app in Instruments (with IO and Memory module) then you can see that memory just keeps growing. (dev/NULL write operations)

For example: if you are metering audio leveles every 1 second.

How can I solve this?

Hi.
Thanks lot for for this post. The last 3 lines of code were really useful.

I also wanted to know if there is a way to record what you are playing without using the mic input.
For example if I am listing to a radio stream, is it possible to record the audio?

Thnaks again for the post
