information about this result code in "Extended Audio File Services Reference". Please help me to resolve it. Thanks. iphone objective-c ios share|improve this question asked Oct 24 '11 at 4:26 Solskjaer 100111 1 Error -50 means there’s an error in the arguments you’ve passed to a function. Make sure that all the arguments you’re passing to ExtAudioFileWrite() are correct. –Bavarious Oct 24 '11 at 4:43 add a comment| 2 Answers 2 active oldest votes how to fix osstatus error -43. up vote 12 down vote This error code is declared in MacErrors.h of the CarbonCore framework. -50 is paramErr. IOW, one of your parameters is invalid. So you will need to verify your parameters, buffer sizes, arguments that you pass and so on to locate the parameter which has been flagged. share|improve this answer answered Dec 27 '11 at 18:31 justin 89.6k10141189 paramErr has often been used as a "catch-all" sort of error, so it might be hard to narrow down. An invalid parameter can mean almost anything. –StilesCrisis Jun 3 '13 at 21:51 1 Pay closer attention to AudioStreamBasicDescription –Ramesh Nov 7 '13 at 23:22 1 Good answer..

(OSStatus error -50.)” up vote 1 down vote favorite 1 http://stackoverflow.com/questions/7871298/osstatus-error-50 I'm trying to debug a MIDI issue in a complex iOS / Objective-C software. It appears on this call : OSStatus s; MIDIClientRef midi_client_ref; s = MIDIClientCreate((CFStringRef)@"MIDIPlayerSetup MIDI Client", NULL, NULL, &midi_client_ref); Most of the time everything works fine but sometimes the returned OSStatus is a -50 code (bad parameter). But as you can see and like in many example of MIDIClientCreate on the web, the explicit parameters can't really be http://stackoverflow.com/questions/29411341/midiclientcreate-the-operation-couldnt-be-completed-osstatus-error-50 the problem. I even tried to have an unique name with no effect. To orientate my search, I would need to have a more precise idea of what is going on in the underlying client creation that could provoke this bad parameter issue. Any guess is welcome ! UPDATE : someone got the same issue here and solved it. He says "It was caused by an uninitalised variable.". That's an indication, but not enough to lead me to my mistake... ios objective-c core-audio coremidi share|improve this question edited Apr 4 '15 at 15:43 asked Apr 2 '15 at 11:02 Pierre Mardon 165215 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote accepted I contacted Apple and this is an internal CoreMIDI bug (until iOS8.3 at least) that was unknown until now. From the support : MIDIClientCreate itself will return -50 in only two scenarios: 1) If outClient itself is NULL so in the above you forget to take the address of client. 2) If the MIDI server has an issue getting a process ID back internally I ensured the address of the client I provide is ok so in my case that is 2). Reproducting the bug : I then noticed that I had several calls

I've been following the Apple Developer documentation for using Audio Services to record audio and I keep getting this error whatever I do. I can record audio fine using AVAudioRecorder into any format but my end game is to obtain a normalised array of floats from the input data in order to apply an FFT to it (sorry for the noob phrasing I'm very new to audio programming). Here's my code: - (void)beginRecording { // Initialise session [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayAndRecord error:nil]; [[AVAudioSession sharedInstance] setActive:YES error:nil]; state.dataFormat.mFormatID = kAudioFormatLinearPCM; state.dataFormat.mSampleRate = 8000.0f; state.dataFormat.mChannelsPerFrame = 1; state.dataFormat.mBitsPerChannel = 16; state.dataFormat.mBytesPerPacket = state.dataFormat.mChannelsPerFrame * sizeof(SInt16); state.dataFormat.mFramesPerPacket = 1; //AudioFileTypeID fileID = kAudioFileAIFFType; state.dataFormat.mFormatFlags = kLinearPCMFormatFlagIsBigEndian | kLinearPCMFormatFlagIsSignedInteger | kLinearPCMFormatFlagIsPacked; OSStatus err = AudioQueueNewInput(&state.dataFormat, handleInputBuffer, &state, CFRunLoopGetMain(), kCFRunLoopCommonModes, 0, &state.queue); printf("%i", err); // this is always -50 i.e. invalid parameters error deriveBufferSize(state.queue, state.dataFormat, 0.5, &state.bufferByteState); for (int i = 0; i < kNu

I'm using this Pitch Detector sample app as my starting point, and it works fine. The only major difference in my project is that I'm also using the Remote I/O unit for audio output. The audio output works fine. Here is my input callback and my initialization code (with error checking removed for brevity). I know it's a lot but error -50 really gives me very little information as to where the problem might be. Input callback: OSStatus inputCallback( void* inRefCon, AudioUnitRenderActionFlags *ioActionFlags, const AudioTimeStamp *inTimeStamp, UInt32 inBusNumber, UInt32 inNumberFrames, AudioBufferList *ioData) { WBAudio* audioObject= (WBAudio*)inRefCon; AudioUnit rioUnit = audioObject->m_audioUnit; OSStatus renderErr; UInt32 bus1 = 1; renderErr = AudioUnitRender(rioUnit, ioActionFlags, inTimeStamp, bus1, inNumberFrames, audioObject->m_inBufferList ); if (renderErr < 0) { return renderErr; // breaks here } return noErr; } // end inputCallback() Initialization: - (id) init { self= [super init]; if( !self ) return nil; OSStatus result; //! Initialize a buffer list for rendering input size_t bytesPerSample; bytesPerSample = sizeof(SInt16); m_inBufferList = (AudioBufferList *)malloc(sizeof(AudioBuffer)); m_inBufferList->mNumberBuffers = 1; m_inBufferList->mBuffers[0].mNumberChannels = 1; m_inBufferList->mBuffers[0].m
