volume

I use the AVAudioPlayer to play a .caf file. My problem is: it is not loud enough for my purpose. Since the ringer sound of the IPhone is much louder I was wondering how I can archive this volume. I already tried to manipulate the .caf file but with no real success. Any ideas? The code I use so far: AVAudioPlayer *newPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL: url error: nil]; self.appSoundPlayer = newPlayer; [newPlayer release]; [appSoundPlayer prepareToPlay]; [appSoundPlayer setVolume: 0.8]; [appSoundPlayer setDelegate: self]; [appSoundPlayer play]; Edit: [appSoundPlayer setVolume

The FoneHome iPhone app has a feature where you can play a sound as part of a local notification. That sound is loud regardless of what the iPhone's volume level is set at. How is it possible to get a local notification (or push) to play an audio alert that is loud independent of what the current iPhone volume level is? I tried just setting the soundName to a WAV file but it plays at whatever the current volume is, and I see no options to set it otherwise. Try using the following code NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/audiofile.mp3", [[NSBundle mainBundle]

Is there a way to prevent the volume indicator view form showing if you press the volume up/down hardware buttons? It's needed for a demo app only. So the method don't need to be App Store safe. IIRC, the presence of a MPVolumeView inhibits the display of the volume indicator overlay. Try sticking it the relevant view and seeing if this is the case. Then you can try various tricks to make it effectively invisible: Make it hidden (or make a superview hidden). Set its alpha (or the alpha of a superview) to 0, or 0.01, or so. Move it off-screen Move it almost off-screen (e.g. so only the top-left

I have a 2 seconds 16bit single channel 8khz wav file and I need to change its volume. It should be quite straightforward, because changing the volume is the same as changing the amplitude of the signal, and I just need to attenuate it, that is to multiply it for a number between 0 and 1. But it doesn't work: the new sound is lower but VERY full of noise. What am I doing wrong? Here is my code: import wave, numpy, struct # Open w = wave.open("input.wav","rb") p = w.getparams() f = p[3] # number of frames s = w.readframes(f) w.close() # Edit s = numpy.fromstring(s, numpy.int16) * 5 / 10 # half

Base question: When I try to use kube-apiserver on my master node, I get command not found error. How I can install/configure kube-apiserver? Any link to example will help. $ kube-apiserver --enable-admission-plugins DefaultStorageClass -bash: kube-apiserver: command not found Details: I am new to Kubernetes and Docker and was trying to create StatefulSet with volumeClaimTemplates. My problem is that the automatic PVs are not created and I get this message in the PVC log: "persistentvolume-controller waiting for a volume to be created". I am not sure if I need to define DefaultStorageClass and
