Getting lots of ugly crashes, although the object builds, installs, and creates itself properly

Am I doing something wrong? Is this a known issue that xtract~ does not work on Mac OS X?

any help appreciated!

Dear all,

Some of you may be aware of, or may have used externals from my flib library (available in the pure-data CVS). flib is now deprecated, and will no longer be developed (at least not by me). Most of the functionality from flib has now been ported to the much more extensive LibXtract library (available via http://sourceforge.net/projects/libxtract).

The library tarball includes a PD external that provides a wrapper for the library's functions. Currently these comprise of:

MEAN,
VARIANCE,
STANDARD_DEVIATION,
AVERAGE_DEVIATION,
SKEWNESS,
KURTOSIS,
CENTROID,
IRREGULARITY_K,
IRREGULARITY_J,
TRISTIMULUS_1,
TRISTIMULUS_2,
TRISTIMULUS_3,
SMOOTHNESS,
SPREAD,
ZCR,
ROLLOFF,
LOUDNESS,
FLATNESS,
TONALITY,
CREST,
NOISINESS,
RMS_AMPLITUDE,
INHARMONICITY,
POWER,
ODD_EVEN_RATIO,
SHARPNESS,
SLOPE,
LOWEST_MATCH,
HPS,
F0,
MAGNITUDE_SPECTRUM,
AUTOCORRELATION,
AUTOCORRELATION_FFT,
AMDF,
ASDF,
MFCC,
DCT,
BARK_COEFFICIENTS,
PEAKS,
FLUX,
ATTACK_TIME,
DECAY_TIME,
DELTA_FEATURE

Some documentation of the code can be found at: http://libxtract.sourceforge.net

There is also a PD help file with the distribution that explains how to use the external, and provides a few usage examples.

Please feel free to email me with any suggestions/questions/comments.

best,

Jamie
