LibXtract is a simple, portable, lightweight library of audio feature extraction functions.

libxtract's Issues

xtract_failsafe_f0() doesn't always return a non-zero f0

Currently there are a number of ways xtract_failsafe_f0() can return an F0 of 0 for spectra with non-zero bins.

The only time it should return zero is when the source is pure silence.

Make LibXtract use double instead of single precision floating point throughout

xtract_spectrum Nyquist is +Inf

Hello Jamie,

I'm running into something that is probably my fault, but I wanted to run it by you to see what you thought the cause could be. Occasionally, I'm seeing a +Inf at nyquist that is throwing off the rest of my extraction chain. I haven't been able to deduce why it's happening yet with my setup and I'm just going to zero it out for the sake of getting this project out the door, but for record's sake here is my setup and usage. Simplified code below:

class XtractNode {
public:
    void initialize();
    void process( double *buf );
private:
    double *mWindow;
    std::vector<double> mFft;
    size_t mNumFramesPerBlock, mNumChannels;
};


void XtractNode::initialize()
{
    mNumFramesPerBlock = 512;
    mNumChannels = 2;

    mWindow = xtract_init_window( mNumFramesPerBlock, XTRACT_HANN );
    mFft.resize( mNumFramesPerBlock );

    xtract_init_fft( mNumFramesPerBlock, XTRACT_SPECTRUM );
}

void XtractNode::process( double *buf )
{
    xtract_windowed( buf, mNumFramesPerBlock, mWindow, buf );

    double argv[4] = {0};
    argv[0] = mSampleRate / (double)mNumFramesPerBlock;
    argv[1] = XTRACT_MAGNITUDE_SPECTRUM;
    argv[2] = 0.f;
    argv[3] = 0.f; // No Normalisation

    xtract_spectrum( buf, mNumFramesPerBlock, &argv[0], mFft.data() );
}

After xtract_spectrum, I'm seeing tha buf[255] = +Inf, but as I mentioned only rarely - other times the analysis and subsequent feature extraction chain works as expected. Does anything pop out to you that I'm doing wrong, or am I hitting an implementation issue?

Thanks,
Rich

ImportError: No module named _xtract

Hi,

I'm trying to import xtract in a python script. Your test.py in LibXtract/swig/python worked fine, but when I try to import xtract from a simple script I write, it doesn't find the module (even though I've added /usr/local/lib/python2.7/site-packages/libxtract/xtract.py to the PYTHONPATH).It says:

File "test1.py", line 5, in <module> import xtract ImportError: No module named xtract

But now, even if I save my python script in LibXtract/swig/python and do import xtract I get:

import xtract File "/Users/jonathan/Desktop/LibXtract/swig/python/xtract.py", line 31, in <module> _xtract = swig_import_helper() File "/Users/jonathan/Desktop/LibXtract/swig/python/xtract.py", line 23, in swig_import_helper import _xtract ImportError: No module named extract

Thanks for your help!

xtract_lowest_value bug

If the last element in the input array is below or equal to the threshold it will always be returned.

xtract_irregularity_j issue

The function accesses the (N + 1)th element of the input data.

If using the output of xtract_spectrum this will cause the first piece of bin frequency data to be used in the calculation unless you pass (spectrumLength / 2 - 1) as the value for N. If you do that it makes it inconsistent with how one would use xtract_irregularity_k.

Changing the first line in the function body from:

int n = N

to:

int n = N - 1

Makes everything more consistent.

xtract_f0 input vector and results

Hi,

even though this seems pretty obvious I want to double check that xtract_f0 only accepts the spectrum to get the pitch, the results then should be the frequency in Hz, is this correct?

I'm testing the function with a software that generates tones and the results don't match, basically higher tones generate small numbers and lower tones generate big ones.
Also the function seems to ignore input signals below 100Hz, the pcm signal is oscillating but the f0 doesn't move and I'm looking at the raw data.
If help I can upload a short video to show the problem.

thanks.

make install error

Hi,

I'm trying to install LibXtract with the sudo make install command, but I am getting the following error message:

Making install in puredata
install -d /usr/local/lib/pd/extra
install -m 644 ../../examples/puredata/.libs/xtract.pd_darwin /usr/local/lib/pd/extra/xtract~.pd_darwin
install: ../../examples/puredata/.libs/xtract.pd_darwin: No such file or directory
make[2]: *** [install] Error 71
make[1]: *** [install-recursive] Error 1
make: *** [install-recursive] Error 1

I kind of think the "" shouldn't be in the directory /usr/local/lib/pd/extra/xtract.pd_darwin, but then again I'm really no expert...

Could you help me with this problem?

Thanks!

irregularity confusion

I'm a bit confused about the documentation for xtract_irregularity_k and xtract_irregularity_k concerning the size of the data param - should it be the size of the FFT or the size of the magnitude spectrum bins? My hunch is the latter, these are the results I'm getting:

N = blocksize (512):

• xtract_irregularity_k: roughly between 28 - 29
• xtract_irregularity_j: always 0.012

N = blocksize / 2:

• xtract_irregularity_k: between 0.0 - 0.6
• xtract_irregularity_j: very large numbers (in the hundreds of thousands)

Any thoughts?

Thanks,
Rich

SVN mentioned in README.md

I presume LibXtract switched from Subversion to Git permanently. If so, SVN is mentioned several times in README.md .

Switch FFT backend to vDSP / Ooura

Call functions in Java

@jamiebullock How could I call those functions in Java? I have installed the tool by the configuration "./configure --enable-fft --enable-swig --with-java". Thank you.

Make proper documentation for LibXtract

Irregularity K/J

Hi,

there is a random issue with the irregularity, its behaviour seems not consistent and I can't replicate this problem, just happens randomly, at some point it kind of stop working, did you notice this issue before?

libxtract: error:

LibXtract compiled with ooura FFT.
libxtract: error: only power-of-two FFT sizes are supported by Ooura FFT.

xtract_init_fft FFT_SIZE

Hi,

I'm a bit confused abotu the fft size, I tried different settings, but the one that's working doesn't seem to be right.
I'm starting with interleaved pcm buffer of 2048 samples(1024 per channel), therefor I should initialised mPcmData with 1024 samples.
The spectrum array size then should be 1024 too, 512 bin frequencies followed by 512 frequency labels.
The xtract_init_fft initialisation really confuses me, in my understanding the fft size is 512, however the only value that works is 2048, in the screenshot below you can see different results using 2048, 1024 and 512 fft size.

#define PCM_SIZE 1024

// init
mPcmData    = std::shared_ptr<double>( new double[ PCM_SIZE ] );
xtract_init_fft( PCM_SIZE << 1, XTRACT_SPECTRUM );

// ...

// get pcm data 2048 samples
audio::Buffer32fRef buff = mPcmBuffer->getInterleavedData();

for( size_t k=0; k < PCM_SIZE; k++ )
    mPcmData.get()[k] = buff->mData[k*2];

// ...

// get spectrum
argd[0] = SAMPLERATE / (double)PCM_SIZE;
argd[1] = XTRACT_MAGNITUDE_SPECTRUM;
argd[2] = 0.0f;
argd[3] = 0.0f;
xtract_spectrum( mPcmData.get(), PCM_SIZE, _argd, mSpectrum.get() );

Online docs ?

Hi!

I have been looking for a library like that for a while, and that look very promising! Any place where I could find docs online?
I have tried to look for what features are available, and there doesn't seem to be "perceived loudness", are you planning to implement it in the future?

Change license to MIT

Deprecate xtract_init_fft() for xtract_init_spectrum() and `xtract_init_autocorrelation_fft()

What should I set to java.library.path

@jamiebullock Thank you for your instructions. The test.java works very well. When I call the functions in my project, I fail to load the library "jxtract". Where is the ".libs" in "java.library.path=.libs"? What should I set to java.library.path? Thank you so much!

xtract_smoothness int arguments

Hi,

xtract_smoothness as well as some other functions, require a pointer to an array of integers, would it be possible to uniform all the functions in order to only accept pointers to array of double or is it an issue?

normalised values and function descriptor

Hi,

I'm trying to find a consistent way to normalise the scalar values, I thought to use the descriptor to get min and max values, but I noticed that not all the functions has a descriptor, is there another way to get min/max values for each function?

Make return codes their own type instead of int

Mac, malloc scribble and FFT

Hello Jamie. When using the built in Accelerate framework and malloc_scribble is enabled, the last elements of the fft structure are non-zero. (Throwing off pretty much scalar functions!)

fix...(clear the structure instead of just malloc).

xtract_init_vdsp_data.c
vdsp_data->fft.realp = (double *) calloc((N >> 1) + 1,sizeof(double));
vdsp_data->fft.imagp = (double *) calloc((N >> 1) + 1,sizeof(double));

Peak interpolation seems to be out by one bin for xtract_peaks()

To reproduce:
Extract the peak spectrum of a sine tone and window size of 1024

Expected:
A single peak at the frequency of the sine tone

Actual:
A single peak around 50Hz below the sine frequency (dependent on block size)

Could you please help,

Fail to install

I can't find configure in the directory.

Pythong bindings installed to wrong location

It looks like the Python bindings are always installed to /usr/local/lib rather than to the site-packages or dist-packages for the python that is being used. The build seems to find python in its path, but goes ahead and installs to /usr/local/lib.

Not sure how to fix this in this build system but I as able to copy the "/usr/local/lib/python2.7/dist-packages/libxtract" directory to where I needed it to get it running for the Python I was using.

It would probably be good to change this to use setuptools or distribute instead.

Errors building the MSP external. Compiled version available?

Hallo,
xtract seems quite interesting. I like the lightweight do one thing and do it well design. Can't wait to try it out, but I struggle compiling the xtract~ external.

I'm on OSX 10.9. xtract worked, but "cd examples/MSP/ && make" not.
Probably just wrong dependencies or parameters. Which OSX SDK and Max SDK did you use?
Or can I get a compiled Version somewhere?

Write LibXtract unit tests

fft configure problems and make errors

I am trying to install LibXtract on my MacOSX, but it won't work.
First of all, when I configure everything, I get the following message:

Summary:

fft: no (not using fftw3, no fft functions)
simpletest example: yes
PD external: yes

Although I have installed fftw 3.3.3. I tried by adding --with-ooura, but it won't change to fft: yes. Then when I hit make, the following message appears:

Undefined symbols for architecture x86_64:
"_xtract_init_fft", referenced from:
_main in simpletest.o
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status
make[3]: *** [simpletest] Error 1
make[2]: *** [all-recursive] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

Are these problems linked? Does the make not work because it cannot find the fftw3 or is it another problem?

Thanks for helping!

vDSP_ctozD malloc error C++

I'm trying to implement simpletest.c example in c++, the app throws malloc error, while running Guard Malloc the app breaks on vDSP_ctozD called by XTRACT_SPECTRUM, however despite it breaks, it output the data correctly(spectral bins, MFCCs).

How to get result vectors?

@jamiebullock I am playing your awesome tool in Java but the result makes me confusing when extracting the result from the vector extractions, e.g. xtract_spectrum.

    int len = 1000;
    int retval = 0;
    float sampleRate = 16000.0f;
    float result[] = new float[len];
    float arg[] = new float[3];
    arg[0] = sampleRate / len;
    arg[1] = 0;
    arg[2] = 0;
    float data[] = new float[len];

    Random rand = new Random();
    for (int i = 0; i < len; i++) {
        data[i] = rand.nextFloat();
    }

    retval = xtract.xtract_spectrum(data, len, arg, result);

"result" has only one non-zero value at result[0]. Is it correct?

BTW, I met fatal errors when I was calling xtract_autocorrelation, xtract_amdf and xtract_asdf to extract a sequence, whose length is over 7.

Gammatone frequency cepstral coefficients (gfcc), exhibits superior noise robustness to mfcc.

Not calling ldconfig after install

It looks like a call to "/sbin/ldconfig" is missing when installing for Ubuntu 12.04. When I try to use the Python bindings I get an error that libxtract.so.0 is not found:

It looks like Ubuntu has that in a library called 'libbsd'. But even if I make sure that is installed, it isn't linking to the library.

node.js bindings?

Hi Jamie,

Any chance you would implement node.js bindings :) ?

autocorrelation_fft crash and other issues

Hi,

there is a consistent issue with my app, after a while it usually crash, I didn't spend time digging the problem yet, but it seems to be related to the auto correlation fft.
Generally this function seems causing quite a few problems, sometimes it doesn't work, sometimes it stop all the other features to work properly like all the function results are 0.

did anybody notice these issues before?

Bark last bin

Hi,

I'm using XTRACT_BARK_BANDS to set the number of bins, however the last one in the array seems a pointer to nothing.

EDIT: somehow today the feature seems working properly, I can't replicate the issue which makes me scratch my head, I can't figure out why this is happening inconsistently
