WARNING: [0x38cb1000] 998: Failure to setup sound, err = -50
I try to use any formats like m4a and it also 0 byte size. Thanks for any help.
EDIT:
In the same time i try to record audio and update my UI with animation
- (void)commanClickOnPetal:(FlowerObject *)flowerObject andButton:(UIButton *)sender {
if ([[NSUserDefaults standardUserDefaults] boolForKey:flowerObject.imageName] == NO || ![[NSUserDefaults standardUserDefaults] boolForKey:flowerObject.imageName]) {
[self.flowerObject changeRecordedState:YES andKey:flowerObject.imageName];
self.view.userInteractionEnabled = NO;
[self playFirstSound];
[self initRecorderWithName:[NSString stringWithFormat:@"%@sound", flowerObject.imageName]];
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, 10 * NSEC_PER_SEC);
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
[self startRecording];
[self.recordIdentifierLabel setHidden:NO];
[UIView animateWithDuration:1.f
delay:0.f
options: UIViewAnimationOptionRepeat | UIViewAnimationCurveLinear | UIViewAnimationOptionAutoreverse
animations:^{
[self.recordIdentifierLabel setAlpha:0.0f];
} completion:nil];
[UIView transitionWithView:sender duration:29.0f options:UIViewAnimationOptionTransitionCrossDissolve | UIViewAnimationOptionAllowAnimatedContent animations:^{
[sender setBackgroundImage:[UIImage imageNamed:[NSString stringWithFormat:@"%@BW",flowerObject.imageName]] forState:UIControlStateNormal];
} completion:^(BOOL finished) {
self.view.userInteractionEnabled = YES;
[self.recordIdentifierLabel setHidden:YES];
}];
});
} else {
[self playSoundFromPetal:[NSString stringWithFormat:@"%@sound", flowerObject.imageName]];
}
}
And here is my method with recorder init:
- (void)initRecorderWithName:(NSString *)name {
self.recordName = [NSString stringWithFormat:@"%@.wav",name];
NSArray *pathComponents = [NSArray arrayWithObjects:
[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject],
self.recordName, nil];
NSURL *outputFileURL = [NSURL fileURLWithPathComponents:pathComponents];
self.currentSession = [AVAudioSession sharedInstance];
[self.currentSession setCategory:AVAudioSessionCategoryRecord error:nil];
NSMutableDictionary *recordingSettings= [[NSMutableDictionary alloc] init];
[recordingSettings setValue:[NSNumber numberWithInt:kAudioFormatLinearPCM] forKey:AVFormatIDKey];
[recordingSettings setValue:[NSNumber numberWithFloat:44100.0] forKey:AVSampleRateKey];
[recordingSettings setValue:[NSNumber numberWithInt: 2] forKey:AVNumberOfChannelsKey];
[recordingSettings setValue:[NSNumber numberWithInt: 16] forKey:AVLinearPCMBitDepthKey];
[recordingSettings setValue:[NSNumber numberWithBool: NO] forKey:AVLinearPCMIsBigEndianKey];
[recordingSettings setValue:[NSNumber numberWithBool: NO] forKey:AVLinearPCMIsFloatKey];
[recordingSettings setValue:[NSNumber numberWithInt: AVAudioQualityHigh] forKey:AVEncoderAudioQualityKey];
recorder = [[AVAudioRecorder alloc] initWithURL:outputFileURL settings:recordingSettings error:NULL];
recorder.delegate = self;
recorder.meteringEnabled = YES;
[recorder prepareToRecord];
}
After recording i send sound by email using MailCore but, file is 0 byte. The recording continue 30 second and after it call method [self stopRecording]
- (void) startRecording {
if (!recorder.recording) {
AVAudioSession *session = self.currentSession;
[session setActive:YES error:nil];
[recorder record];
self.timer = [NSTimer scheduledTimerWithTimeInterval: 1.0 target:self selector:@selector(updateCountdown) userInfo:nil repeats: YES];
} else {
[recorder stop];
}
}
- (void) stopRecording {
[recorder stop];
AVAudioSession *audioSession = [AVAudioSession sharedInstance];
[audioSession setActive:NO error:nil];
self.dictionaryWithRecords = (NSMutableDictionary *) @{@"URL": recorder.url,
@"Name": self.recordName};
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
if ([[DBEmailSender sharedManager] emailAddress] != nil) {
[[DBEmailSender sharedManager] sendMailWithAddress:[[NSUserDefaults standardUserDefaults] objectForKey:@"email"] andCode:nil andFilePath:[self.dictionaryWithRecords objectForKey:@"Name"]];
}
});
}
- (void)updateCountdown {
self.tick += 1;
double seconds = fmod(self.tick, 60.0);
if (seconds == 29) {
self.tick = 0;
seconds = 0;
[self.timer invalidate];
self.timer = nil;
[self stopRecording];
}
}
And here is i play my sound by button click:
- (void)playSoundFromPetal:(NSString *)soundName {
SystemSoundID mySSID;
NSString *path = [NSTemporaryDirectory() stringByAppendingPathComponent:soundName];
AudioServicesCreateSystemSoundID((__bridge CFURLRef)[NSURL fileURLWithPath: path], &mySSID);
AudioServicesPlaySystemSound(mySSID);
}
There can be many reasons for that but in my case, there was another object already using AVAudioSession for playing audio.
