Hi

I tried to debug using Sonic Visualiser. Then prompts  "Unhandled exception at 0x0256a966 (vamp-example-plugins.dll) in Sonic Visualiser.exe: 0xC0000005: Access violation reading location 0xcdcdcdd1" and asked to break or continue. I Tried to continue and the stack traces are:

Hi.

I got this error log, what does it mean?


Faulting application sonic visualiser.exe, version 0.0.0.0, faulting module vamp-example-plugins.dll, version 0.0.0.0, fault address 0x0009a966.

Hazel

Hi

It says 'Unable to start Sonic Visualiser. The system cannot find the file specified'

Hazel

Hi.

I've tried to configure the Debug command as you say so but still I get the same result. It still crashes.

Do you mean I have to get the codes of Sonic V. to run in Visual Studio?

I am using ver.2.0 of the SDK libraries and headers.

Thanks a lot.

Hazel

Hi.

I tried the codes you've given me, but still SV crashes as it starts.

What could possibly be the problem here?

Thanks.

Hi

SV crashes as soon as I start it up (with my dll installed).


const VampPluginDescriptor *vampGetPluginDescriptor(unsigned int version,
                                                    unsigned int index)
{
 if (version < 1) return 0;

return vocalRangeAnalyzerPlugin.getDescriptor();
    return 0;
}

--How do I use vamp-simple-host? And what debugger do you suggest?

Thanks

Hazel

Hi.

I'm back. Regarding what I said that the .dll file is not running in SV, whenever I tried to open SV, it crashes down. It does not continue to open.

Where is the problem here? In the codes?

Pls. help. Thanks.

Hazel

Also, how do I remove the example plugins of vamp. I want only my plugin to be built. I tried deleting the examples.cpp files but everytime I build it, there's an error of cannot find files.

Thanks

Hazel

hi,

can you please look at my codes in the process call, am i doing the right coding.

VocalRangeAnalyzerPlugin::FeatureSet
VocalRangeAnalyzerPlugin::process(const float *const *inputBuffers,
                                 Vamp::RealTime timestamp)
{
    FeatureSet returnFeatures;

    if (m_stepSize == 0) {
        std::cerr << "VocalRangeAnalyzerPlugin::process:  Plugin not initialised" << std::endl;
        return returnFeatures;
    }

    for (size_t i = 0; i < m_stepSize; ++i) {
        for (size_t j = 0; j < m_channelCount; ++j) {
            fvec_write_sample(m_ibuf, inputBuffers[j], j, i);
        }
    }

      calculate();

      if (minFreq >= 80 && maxFreq <= 310){
         feature.label = "bass";}

      else if(minFreq >= 100 && maxFreq <= 440){
         feature.label ="baritone";}
         
      else if(minFreq >=130 && maxFreq <= 500){
         feature.label = "tenor";}

      else if(minFreq >= 160 && maxFreq <= 650){
         feature.label = "alto";}

      else if(minFreq >= 210 && maxFreq <= 900){
         feature.label = "mezzo-soprano";}

      else if(minFreq >= 270 && maxFreq <= 1100){
         feature.label = "soprano";}

   
   Feature feature;
    feature.hasTimestamp = true;
    feature.timestamp = m_currentOnset +
            RealTime::frame2RealTime(i * m_stepSize, m_inputSampleRate);
   feature.hasDuration = true;
    feature.duration = offTime - m_currentOnset;
    feature.values.push_back(freq);

    returnFeatures[0].push_back(feature);
    return returnFeatures;
}

void
VocalRangeAnalyzerPlugin::calculate()
{
   float freq = aubio_pitchdetection(m_pitchdet, m_ibuf);
   

   for(int i=0; i<m_stepSize; i++)
   {
      if(freq < minFreq){
         minFreq = freq;
      }
      else
         if(freq > maxFreq){
            maxFreq = freq;
         }

   isFirstTime(false);
   }
}
//consider all has been initialized

do i miss something, there's no error, i got a dll file but then it is not running in sonic v.

please help. thanks.

I just want to know the concept on the output of QM Key Detector, in which it is not processed per processing block.

Also, do you have any idea on how to get the minimum and maximum frequency of the signal using the aubio pitch detection plugin.

Thanks ahead.

Hazel

Thanks. I got it anyway.

I would like to ask if you have codes for QM Plugins. I would appreciate if I you'll give me one.

Thanks..

Hazel

Hi,

I got to build vamp-example plugins including my own plugin but the .dll file of my project is not recognized by sonic Visualiser.
Whenever I open Sonic V, it encounters a problem and need to be close.


Thanks


Hazel

Hi

I solved that errors which I stated above, now I got to compile all the codes but then I got error in linking..

These are the errors..

I really cant move forward...pls help..

Thanks, I got rid of the 'malloc' errors.

I have another problem with these errors.

--error C2057: expected constant expression
--error C2466: cannot allocate an array of constant size 0
--error C2133: 'buf' : unknown size

here's some of the codes.

//pitchschmitt.h

#ifndef _PITCHSCHMITT_H
#define _PITCHSCHMITT_H


#ifdef __cplusplus
extern "C" {
#endif

typedef struct _aubio_pitchschmitt_t aubio_pitchschmitt_t;

smpl_t aubio_pitchschmitt_detect (aubio_pitchschmitt_t *p, fvec_t * input);
aubio_pitchschmitt_t * new_aubio_pitchschmitt (uint_t size, uint_t samplerate);
void del_aubio_pitchschmitt (aubio_pitchschmitt_t *p);


#ifdef __cplusplus
}
#endif

#endif /* _PITCHSCHMITT_H */


//pitchschmitt.cpp
//part where i got those errors

#include <cstdlib>
#include "aubio_priv.h"
#include "sample.h"
#include "pitchschmitt.h"

smpl_t aubio_pitchschmitt_detect (aubio_pitchschmitt_t *p, fvec_t * input)
{
  signed short int buf[input->length];//errors occur here
  uint_t i;
  for (i=0; i<input->length; i++) {
    buf = input->data[0]*32768.;
  }
  return aubio_schmittS16LE(p, input->length, buf);
}

could you help me this compiler errors.

Hi,

I got to compile some of the codes of aubio and got this error from sample.cpp

----error C3861: 'malloc': identifier not found

How do I solved this.
