Hi,

I am new to VAMP. I'm trying to use the Tempo Tracker to detect the tempo of various samples. When I give it aif files everything works fine as follows:

sonic-annotator -t temptest.n3 drum_loop_125.aif -w csv --csv-stdoutCSVFeatureWriter::setParameters
stdout ->
RDFTransformFactory: NOTE: Transform is:
<transform
    id="vamp:qm-vamp-plugins:qm-tempotracker:tempo"
    pluginVersion=""
    program=""
    stepSize="512"
    blockSize="1024"
    windowType="hanning"
    startTime="0.000000000"
    duration="0.000000000"
    sampleRate="0">
  <parameter name="dftype" value="3"/>
  <parameter name="method" value="1"/>
  <parameter name="whiten" value="0"/>
</transform>

NOTE: Transform does not specify a sample rate, using default rate of 44100

When I give it a wav file I get the following output:

============================
How can I tell whats causing the process to abort at 90%? Am I doing something wrong? I really just want the BPM. Any help will be greatly appreciated. FYI. I am using version 1.6 of the qm plugins. 

Thanks,
Ashley
