However, when I start listening with SCListener, the music fades out and stops. I have set the kAudioSessionCategory_PlayAndRecord property on the audio se...

I fail to see a My.Computer.Webcam or My.Computer.Microphone, both of which would probably have been a nice addition. Thanks for the help! If there is no easy method for doing this, what is the name of the driver that handles this and what methods s...
Hi guys, I'm having a few problems detecting whether a microphone is detected or not. I'm running the function Microphone.getMicrophone() and that should return null if there is no microphone attached, or if the user has clicked Deny on the security panel, right? The problem I'm facing is, on some computers where there is no microphone ...

Hi, I have some questions about Directsound and windows mixers. My goal is to enumerate all microphones and be able to change the input volume of each one. I think i'm not far from the solution, but I don't find what is wrong in my code. Here is what I have done: - I enumerate all input devices and get a GUID for each one - I use a meth...

It's displaying an error message saying there's no mic available on the device. The thing is, the app does nothing whatsoever with audio, and I can't find anything related in the project settings. The ...

Greetings, I'm trying to write a program in Python which would print a string every time it gets a tap in the microphone. When I say 'tap', I mean a loud sudden noise or something similar. I searched in SO and found this post: http://stackoverflow.com/questions/1797631/recognising-tone-of-the-audio I think PyAudio library would fit my...
I've been waiting for the day that flash gets access to raw audio data. That day is now, but i'm not sure how to get 10.1 working in CS4.

Hi all, In my app, I am using the AVAudioRecorder to detect input from the microphone. However, I need to create a high-pass filter so that I only register higher-pitched sounds. I've looked into FFT, but I can't figure out how to implement it. So, now I'm looking to kind-of fudge an FFT with a high-pass filter. Any help would be gre...
