Hi,
I had a go with the audiofile command las few days.
I managed to load wav files, but can't save any

here is the part of the code that's not working : (it's included in a function that is called at callback)

CODE:

for (int i = 0; i < m_size; ++i) {sdkSetSampleAudioFile(audioFile, 1,i, m_buffer[i]);}sdkSetChannelsAudioFile(audioFile, 1);sdkSetSizeAudioFile(audioFile, m_size);sdkSaveToDiskAudioFile(audioFile, tempChar, 1);}

/////////////////////////////
if I run it, it will return errors :
[2] Error :
[HydroGen OP V5] CallBack, paramIndex=19

///////////////////////////////////////
tried with

sdkSetChannelsAudioFile(audioFile, 1);
sdkSetSizeAudioFile(audioFile, m_size);
before
for (int i = 0; i < m_size; ++i) {
sdkSetSampleAudioFile(audioFile, 1,i, m_buffer);

same thing
/////////////////////////////////////////

if I comment it and run only SetChannelsAudioFile and SetSizeAudioFile :

[6] Error :
bad pointer in SetChannelsAudioFile
[8] Error :
bad pointer in SetSizeAudioFile

//////////////////

with only: sdkSetSampleAudioFile(audioFile, 1,i, m_buffer);

[2] Error :
[HydroGen OP V5] CallBack, paramIndex=19

/////////////////////////////////////
with only: sdkSaveToDiskAudioFile(audioFile, tempChar, 1);

SDK_SaveToDiskAudioFile :
[0] Error :
PROC:SaveToDiskAudioFile
ERROR:Access violation at address 000000000136CDDE in module 'Usine.exe'. Read of address
0000000000001190

if anyone has a working example using sdkSaveToDiskAudioFile, could you please show it to me !

thanx

Finally I will make some code from scratch with ofstream direct in C++ so I will be able to adress the metata datas in the wave file as well.

wish me luck

Hi,
I'm trying to use the "audiofile" class in the SDK to make a multitrack file but I get some errors :
My idea is to have a multitrack wave file that I can save (or load) and populate it with samples
But I think I get something wrong.
If I want to have a recorder like the "audios ampler recorder" module, do I have to save the samples in a buffer (RAM) and then use the audiofile to save the wave file to disk ?
I'm a bit lost in here.

in .h

TAudioFilePtr audiofile1;

in .cpp

// constructor
multitrackrecorder::multitrackrecorder()

{
audiofile1 = sdkCreateAudioFile();
}

....

//-----------------------------------------------------------------------------
// initialisation
void multitrackrecorder::onInitModule (TMasterInfo* pMasterInfo, TModuleInfo* pModuleInfo)
{
sdkSetChannelsAudioFile(audiofile1, numOfAudiotInsOuts);
sdkSetSizeAudioFile(audiofile1, 60 * sdkGetSampleRate());

}

When loaded in Usine, I get those error messages :
[4] Error :
bad pointer in SetChannelsAudioFile
[6] Error :
bad pointer in SetSizeAudioFile

any idea ?
thanks
