not recording.

i run it but not recording. why?

[davut5]

maybe you can update it. Maybe use avaudioengine

I've tested the code against latest Xcode version with iOS 9.

It still works as it should. It listens to the microphone input, the gain can be changed and playback also works. How did you test the code and what was your expectation?

I wont update the code to avaudioengine as my example should be simple as simple as possible for DSP.

Maybe this one fits more for your needs. Looks like a good template to start:

Check out the PDF in the repo.

thanks for your interest. SwiftyAudio works great. is it possible to record voice and background music together. Like a karaoke app. i want to record mic voice and headphone ear together.
