Ok, i find solution couple years ago. I change record logic to

NSDictionary *settings = [NSDictionary dictionaryWithObjectsAndKeys:
                          [NSNumber numberWithInt:kAudioFormatMPEG4AAC], AVFormatIDKey,
                          [NSNumber numberWithFloat:16000], AVSampleRateKey,
                          [NSNumber numberWithInt:2], AVNumberOfChannelsKey,
                          [NSNumber numberWithInt:AVAudioQualityMedium], AVSampleRateConverterAudioQualityKey,
                          [NSNumber numberWithInt:64000], AVEncoderBitRateKey,
                          [NSNumber numberWithInt:8], AVEncoderBitDepthHintKey,
                          nil];


error = nil;

_recorder = [[AVAudioRecorder alloc] initWithURL:url settings:settings error:&error];

and this recorded file play on iOS, Android and MacOS/Win. So it's all.
