Error in pitchschmitt.c

["Paul Dean" <PaulD@4stlaw.com>]

I’m working on getting AUBIO to compile on my VS2005 compiler. I run into an error I have a question about.

In the aubio_pitchschmitt_detect() function, an array is declared with an un-initiated size because we don’t know what size input->length is.

Does input->length’s value change during run-time or is it static? If it’s dynamic, we may have to use a vector here.

 

 

***** pitchschmitt.c ******

.

.

.

 

smpl_t aubio_pitchschmitt_detect (aubio_pitchschmitt_t *p, fvec_t * input)

{

  short buf[input->length];      ß-- Compiler Error: cannot allocate an array of unknown size.

  uint_t i;

  for (i=0; i<input->length; i++) {

    buf[i] = (short)(input->data[0][i]*32768.);

  }

  return aubio_schmittS16LE(p, input->length, buf);

}

.

.

.

 

 

 

 

Also.. in onsetdetection.c in the aubio_onsetdetection_kl() function, this line give me a warning I’m not sure what to do with.

 

******* onsetdetection.c *********

.

.

.

if (isnan(onset->data[i][0])) onset->data[i][0] = 0.;   ß-- Comiler Warning: 'isnan' undefined; assuming extern returning int.

.

P.S. I was able to get AUBIO to comple in VS2005 with the aubio_pitchschmitt_detect() function commented out.

     I’m using test-onsetdetection.c to create the executable. I’ll test it’s functionality to see that everything works.

     Then I’ll post a VS2005 Project along with a CMAKE script soon J
