I have implemented AVAudiorecorder for recording and playing voice for 10 secs.it is working fine with iOS 7.But when i run the same code on ios8 ,it is not working please help.
Here is a source Code.
//Below is my code for recording and Playing.
//Here is the Recording code which records sound for 10 secs
AVAudioSession *audioSession = [AVAudioSession sharedInstance];
NSError *err = nil;
[audioSession setCategory :AVAudioSessionCategoryPlayAndRecord error:&err];
if(err){
return;
}
[audioSession setActive:YES error:&err];
err = nil;
// Setup audio recording
recordSetting = #{AVFormatIDKey: #(kAudioFormatMPEG4AAC),
AVEncoderAudioQualityKey: #(AVAudioQualityLow),
AVNumberOfChannelsKey: #1,
AVSampleRateKey: #22050.0f};
recorderFilePath = [NSString stringWithFormat:#"%#/MySound.wave", DOCUMENTS_FOLDER];
NSData *postData = [NSData dataWithContentsOfFile:recorderFilePath];
NSURL *url = [NSURL fileURLWithPath:recorderFilePath];err = nil;
NSData *audioData = [NSData dataWithContentsOfFile:[url path] options: 0 error:&err];
if(audioData)
{NSFileManager *fm = [NSFileManager defaultManager];
[fm removeItemAtPath:[url path] error:&err];}
err = nil;
recorder = [[ AVAudioRecorder alloc] initWithURL:url settings:recordSetting error:&err];
//prepare to record
[recorder setDelegate:self];
[recorder prepareToRecord];
recorder.meteringEnabled = YES;
//Please help me out and tell if i have to add/modify something because it is working in ios7.
It seems that there isn't nothing wrong in your code snippet.
I use approximately the same code to make a registration on my iPhone, too.
The only difference with my code is a call to
[recorder recordForDuration:(NSTimeInterval) 10];
in order to start the registration for 10 seconds

I am trying to update the mac app which is distributed outside app store so followed the process as suggested here
After downloading the .pkg file i am opening the using [[NSWorkspace sharedWorkspace] openFile:filePath.path]; but after successfully installed app is not getting opened so what do i need to do so that after app update i want app to restart
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
NSURL *URL = [NSURL URLWithString:#"http://macappsupdate/localapp.pkg"];

Any Suggestions ?
Thanks in Advance !!
I am creating a voice communication feature in my application that sends voice notes between users via a web server, however during
testing I am experiencing an error with playing back message I created
with AVAudioPlayer. The AVAudioplayer just returns a null value.
How do I play an audio file from the URL link with AVAudioPlayer?
if (!self.audioRecorder.recording) {
NSURL *url = [NSURL URLWithString:[#"http://.../sound.mp4"]];
NSLog(#"%#", url);
NSLog(#"PlayBack");
NSData *audioData = [NSData dataWithContentsOfURL:url];
NSString *filePath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES) objectAtIndex:0]
stringByAppendingPathComponent:#"sound1.caf"];
[audioData writeToFile:filePath atomically:YES];
NSError *error;
NSURL *fileURL = [NSURL fileURLWithPath:filePath];
self.audioPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:fileURL error:&error];
if (self.audioPlayer == nil) {
NSLog(#"%#", [error description]);
NSLog(#"%#", [self.audioPlayer description]);
}else
[self.audioPlayer play];
}else [self.audioRecorder stop];
please try out this code:
- (void) playMessageSound : (NSString *) filename{
self.soundFilename = filename;
//[[RBDMuteSwitch sharedInstance] detectMuteSwitch];
NSString *name = [filename stringByDeletingPathExtension];
NSString *extension = [filename pathExtension];
NSString *filePath = [[NSBundle mainBundle]pathForResource:name ofType:extension];
NSURL *fileUrl = [NSURL fileURLWithPath:filePath];
NSError *error;
self.audioPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:fileUrl error:&error];
self.audioPlayer.numberOfLoops = 0;
self.audioPlayer.volume = 1.0;
[self.audioPlayer play];
}
check this
NSString* resourcePath = #""; //your url
NSData *_objectData = [NSData dataWithContentsOfURL:[NSURL URLWithString:resourcePath]];
NSError *error;
app.audioPlayer = [[AVAudioPlayer alloc] initWithData:_objectData error:&error];
app.audioPlayer.numberOfLoops = 0;
app.audioPlayer.volume = 4.0f;
[app.audioPlayer prepareToPlay];
if (app.audioPlayer == nil)
NSLog(#"%#", [error description]);
else
[app.audioPlayer play];
I'm trying to play an audio file when a button is tapped.
If I step through my code it works, but if I just tap on the button no sound is played.
Here is my code:
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
AVAudioPlayer * player;
NSString * path = [[NSBundle mainBundle] pathForResource:#"soundOne" ofType:#"mp3"];
NSURL * url = [NSURL fileURLWithPath:path];
player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
[player play];
Is this the appropriate way to play audio? Nothing is being flagged as being deprecated.
I also see this message in the debugger:
AudioQueue: request to trim 0 + 2690 = 2690 frames from buffer containing 1152 frames
EDIT:
This code works.
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"soundOne"
ofType:#"mp3"];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:filePath];
self.audioPlayer = [[AVAudioPlayer alloc]
initWithContentsOfURL:fileURL error:nil];
[self.audioPlayer prepareToPlay];
self.audioPlayer.currentTime = 0;
[self.audioPlayer play];
How can I play audio with the mute button on?
Here is the code I have tried for this:
CFStringRef state;
UInt32 propertySize = sizeof(CFStringRef);
OSStatus audioStatus = AudioSessionGetProperty(kAudioSessionProperty_AudioRoute, &propertySize, &state);
if (audioStatus == kAudioSessionNoError) {
//NSLog(#"audio route: %#", state);
return (CFStringGetLength(state) <+ 0);
}
return NO;
Stick this before you call play:
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:&error];
[[AVAudioSession sharedInstance] setActive:YES error:&error];
That should do it.
In one of the views of my app there's a button. When pressed it is supposed to begin taking a video, trigger a sound file to start, and hide itself from view while unhiding another button. The second button is supposed to stop the video recording and make it save. Here's the code I have for the video recording, which initially worked with no problems:
in viewDidLoad:
finishButton.hidden = TRUE;
session = [[AVCaptureSession alloc] init];
movieFileOutput = [[AVCaptureMovieFileOutput alloc] init];
NSError *error;
AVCaptureDeviceInput *videoInput = [[AVCaptureDeviceInput alloc] initWithDevice:[self cameraWithPosition:AVCaptureDevicePositionFront] error:&error];
if (videoInput)
{
[session addInput:videoInput];
}
AVCaptureDevice *audioCaptureDevice = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeAudio];
NSError *audioError = nil;
AVCaptureDeviceInput *audioInput = [AVCaptureDeviceInput deviceInputWithDevice:audioCaptureDevice error:&audioError];
if (audioInput)
{
[session addInput:audioInput];
}
Float64 TotalSeconds = 35; //Total seconds
int32_t preferredTimeScale = 30; //Frames per second
CMTime maxDuration = CMTimeMakeWithSeconds(TotalSeconds, preferredTimeScale);
movieFileOutput.maxRecordedDuration = maxDuration;
movieFileOutput.minFreeDiskSpaceLimit = 1024 * 1024;
if ([session canAddOutput:movieFileOutput])
[session addOutput:movieFileOutput];
[session setSessionPreset:AVCaptureSessionPresetMedium];
if ([session canSetSessionPreset:AVCaptureSessionPreset640x480]) //Check size based configs are supported before setting them
[session setSessionPreset:AVCaptureSessionPreset640x480];
[self cameraSetOutputProperties];
[session startRunning];
and for the button:
-(IBAction)start:(id)sender
{
startButton.hidden = TRUE;
finishButton.hidden = FALSE;
//Create temporary URL to record to
NSString *outputPath = [[NSString alloc] initWithFormat:#"%#%#", NSTemporaryDirectory(), #"output.mov"];
self.outputURL = [[NSURL alloc] initFileURLWithPath:outputPath];
NSFileManager *fileManager = [NSFileManager defaultManager];
if ([fileManager fileExistsAtPath:outputPath])
{
NSError *error;
if ([fileManager removeItemAtPath:outputPath error:&error] == NO)
{
//Error - handle if required
}
}
//Start recording
[movieFileOutput startRecordingToOutputFileURL:outputURL recordingDelegate:self];
finally, under the last button:
[movieFileOutput stopRecording];
and here's the code to save the video:
- (void)captureOutput:(AVCaptureFileOutput *)captureOutput
didFinishRecordingToOutputFileAtURL:(NSURL *)outputFileURL
fromConnections:(NSArray *)connections
error:(NSError *)error
{
NSLog(#"didFinishRecordingToOutputFileAtURL - enter");
BOOL RecordedSuccessfully = YES;
if ([error code] != noErr)
{
// A problem occurred: Find out if the recording was successful.
id value = [[error userInfo] objectForKey:AVErrorRecordingSuccessfullyFinishedKey];
if (value)
{
RecordedSuccessfully = [value boolValue];
}
}
if (RecordedSuccessfully)
{
//----- RECORDED SUCESSFULLY -----
NSLog(#"didFinishRecordingToOutputFileAtURL - success");
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
if ([library videoAtPathIsCompatibleWithSavedPhotosAlbum:outputURL])
{
[library writeVideoAtPathToSavedPhotosAlbum:outputURL
completionBlock:^(NSURL *assetURL, NSError *error)
{
if (error)
{
}
}];
}
}
}
All of this was working just fine. Then I added a few lines so that a song file would play when the start button was pressed.
in viewDidLoad:
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/Song.aiff", [[NSBundle mainBundle] resourcePath]]];
NSError *audioFileError;
player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&audioFileError];
player.numberOfLoops = 0;
[self.player prepareToPlay];
and under the start button:
if (player == nil)
NSLog(#"Audio file could not be played");
else
[player play];
Now when the start button is pressed the song plays with no problems, but the video capture is messed up. Before adding the AVAudioPlayer stuff I would get the "didFinishRecordingToOutputFileAtURL - enter" and "didFinishRecordingToOutputFileAtURL - success" logs when I pressed the finish button, and now I get the first log as soon as I press the start button, nothing happens when I press the finish button, and no video is recorded. If I comment out the lines that make the song play then the video capture works just fine again. Any ideas what's going on here?
- (void)setupAudioSession
{
static BOOL audioSessionSetup = NO;
if (audioSessionSetup)
{
return;
}
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error: nil];
UInt32 doSetProperty = 1;
AudioSessionSetProperty (kAudioSessionProperty_OverrideCategoryMixWithOthers, sizeof(doSetProperty), &doSetProperty);
[[AVAudioSession sharedInstance] setActive: YES error: nil];
audioSessionSetup = YES;
}
- (void)playAudio
{
[self setupAudioSession];
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:#"btnClick" ofType:#"wav"];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:soundFilePath];
AVAudioPlayer *newPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:nil];
[fileURL release];
self.audioPlayer = newPlayer;
[newPlayer release];
[audioPlayer setDelegate:self];
[audioPlayer prepareToPlay];
audioPlayer.volume=1.0;
[audioPlayer play];
}
NOTE: Add the framework: AudioToolbox.framework.
#import <AudioToolbox/AudioServices.h>
NSError *err;
// Initialize audio player
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&err];
audioPlayer.delegate = self;
[audioPlayer play];
With the code above, I'm trying to initialize playback of a .mp3 file, however the playback does not start at all. There is no sound. What am I doing wrong? I have inspected 'err' and there is nothing there.
Edit: After adding AVAudioSession, I'm getting the following error from AVAudioPlayer
The operation couldn’t be completed. (OSStatus error -43.)
Apparently AVAudioPlayer does not support streaming via. HTTP as I was trying to do, so by using AVPlayer instead, I got it working.
Did you initialize a AVAudioSession?
The following works fine for me. Might give you a hint of whats not working for you.
Initializing:
AVAudioSession* session = [AVAudioSession sharedInstance];
[session setCategory:AVAudioSessionCategoryAmbient error:nil];
[session setActive:TRUE error:nil];
Loading:
AVAudioPlayer* audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileUrl error:nil];
audioPlayer.numberOfLoops = 0;
[audioPlayer prepareToPlay];
audioPlayer.volume = 1.0;
Playing:
[audioPlayer play];
Update
To find the right NSRUL for fileUrl, I used this code:
NSURL* fileUrl = [NSURL fileURLWithPath:
[[NSBundle mainBundle] pathForResource:#"MySound" ofType:#"wav"] isDirectory:NO];
And then I added MySound.wav to the project (bundle).
