Any ideas Michael?

Any solution for this Michael?

Thank you,

Snow Leopard 10.6.2

I also have this question open http://stackoverflow.com/questions/10501236/stream-media-from-iphone because when I use a variation of this code, nothing happens: void audioDataReceiver (AudioBufferList bufferList) { double *q = (double *)(&bufferList)->mBuffers[0].mData;

queue = [[NSOperationQueue alloc]init];

for(int i=0; i < strlen((const char *)(&bufferList)->mBuffers[0].mData); i++) {

NSData * dataBuffer = [NSData dataWithBytes:&q[i] length:sizeof(double)];

// NSData * dataBuffer =[NSData dataWithBytes:(&bufferList)->mBuffers[0].mData length:sizeof((&bufferList)->mBuffers[0].mData)];

    client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:[NSString stringWithFormat:@"https://%@/",serverAddress]]];

NSMutableDictionary *parameters = [NSMutableDictionary dictionary];

        NSMutableURLRequest * request = [client multipartFormRequestWithMethod:@"POST" path:[NSString stringWithFormat:@"transmitaudio?id=%@", sessionID] parameters:parameters constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) 
                 {

// [formData appendPartWithFileData:self.audioHandler.dataBuffer name:@"micaudio" fileName:@"sound.caf" mimeType:@"audio/basic"];

                         [formData appendData:dataBuffer];

// NSLog(@”request: %@”,request); // NSLog(@”client: %@”,client); }]; [request setValue:@"audio/basic" forHTTPHeaderField:@"content-type"]; [request setValue:@"99999" forHTTPHeaderField:@"Content-Length"]; [request setValue:@"Keep-Alive" forHTTPHeaderField:@"Connection"]; [request setValue:@"no-cache" forHTTPHeaderField:@"Cache-Control"];

    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
    [queue addOperation:operation];

// NSLog(@”queue: %@”,queue); }

}

I finally got the chance to try my application on a device and not just the simulator. It all works perfectly, except a minor delay, which I will look into.

My question: how can I output the audio through the speakers (the loud ones, so I can achieve a handsfree functionality)? So far, I can only hear the audio through the headphones or If I press my ear against the phone as in a standard conversation.

As always, Thanks:) Stefan

Tried using VPIO. The only problem I’m having with it now is that it seems to automatically lower the gain for all output sounds. When I switch back to RemoteIO, sound levels are back to normal.

I tried disabling kAUVoiceIOProperty_VoiceProcessingEnableAGC and also kAUVoiceIOProperty_DuckNonVoiceAudio, but no dice. Did you find this problem when you were doing Loopy?

I have been working on this stuff for a few days now and i swear every time i find something i hit another wall :(. Do you know why i would be getting the above errors? I coppied and pasted the code into its own MyAudioController.m file with a plain MyAudioController.h file. i have tried changing the file to .mm as well as .c just to troubleshoot but that did not help.

Thank you for making a great piece of plugin.

That refers to the audio unit’s own internal buffer – it’s really quite a minor detail, but it saves a little memory allocation if you’re providing your own buffers instead. If in doubt, it’s save to leave it out, though.

Yep, you’ll get echo cancellation for free, as soon as you start using VPIO.

You’re welcome =)

About this:

// Disable buffer allocation for the recorder (optional – do this if we want to pass in our own) flag = 0; status = AudioUnitSetProperty(audioUnit, kAudioUnitProperty_ShouldAllocateBuffer, kAudioUnitScope_Output, kInputBus, &flag, sizeof(flag));

What buffer does it refer to? I see no difference in the behavior of my application if I decide to disable it or not. I use temporary AudioBuffer and AudioBufferList to store the input data and then copy this data to the Circular buffer you have provided.

Another question: About this Voice-Processing IO Audio Unit and its acoustic echo cancellation. Do I simply use it in my code and this nice echo cancellation effect “magically” appears, or should I do some special configuration beforehand? Does it work at all?

Thank you, you’ve been such a help to me and my beginnings in iOS Audio development. Stefan
