Hi, I am usinf FMOD + unity and trying to create a wav file(with specified name) using the FMOD.OUTPUTTYPE.WAVWRITER method through a script, which is attached to a microphone. Always I am getting the file name fmodoutput.wav. I am having the following codes string fname = “xyz.wav”; FMODUnity.R…

Firstly it’s not safe to close the System object while everything is running in Unity, there is no mechanism to reload everything properly. Some platforms permit switching the output safely at runtime, i.e. they don’t return ERR_Initialized, which platform are you on? However switching output to w…

Thanks Mathew, If I do not use the close(), then I will get the ERR_Initialized as below Error in writing wav file : ERR_INITIALIZED. I used the following code the capture the error var result = FMODUnity.RuntimeManager.CoreSystem.init(128, FMOD.INITFLAGS.NORMAL, Marshal.StringToHGlobalUni(sente…

That is correct, you cannot call System::init while the System is running and you cannot call System::close safely for Unity so using that approach will not work for you. You can however modify our script code where we initialize the FMOD System for the first time, setting it to wav writer at this p…

Mathew, I am able to get dsp now using the following command thisSoundEventChannels.getDSP(0, out dsp); I am not sure, how to attach the dsp to dspgraph and also to write .wav header file. Could you please provide some pointers to some sample for this Thanks

To create a DSP you’d need to use System::createDSP and pass in an FMOD_DSP_DESCRIPTION you’ve defined. The main callback you must implement is DSP_READCALLBACK , that will receive the audio signal. Once created the DSP can be added with ChannelGroup::addDSP . For writing a .wav file you’ll need to r…

Mathew, Thanks for for your reply. I have written the CreateDSP and callback methods as below by using the document and some examples static FMOD.RESULT CallbackMic(ref FMOD.DSP_STATE S, IntPtr In, IntPtr Out, uint Len, int ChInCount, ref int ChOutCount) { FMOD.DSP dsp1; channelGroup.getD…

It’s always good practice to check the error codes returned from each function to ensure everything is working correctly. If you are interested in getting the spectrum of the the signal, using the FFT DSP the way you have should work, you’ll need to add code to query the spectrum of course. If you…

Mathew, Thanks. I did the changes as you suggested, may be I have done some mistake. I do not see any error. Do I need to write into .wav file at call back method Thanks

It’s best to save the samples to a separate buffer so you’re not writing to a file in the callback, but you can for testing purposes.

hey melango Could you please share the code for getting the bytes of the signal here. I am also confused about this problems for a long time. Appreciate for your help!
