I tested this code with the audio files from https://github.com/ludlows/python-pesq (i.e. speech.wav vs speech_bab_0dB.wav) and got the score 1.9688572883605957. There was said, the score should be 1.0832337141036987 for wide band pesq and 1.6072081327438354 for narrow band pesq.

Looking at the examples in https://www.mathworks.com/matlabcentral/mlc-downloads/downloads/submissions/47333/versions/3/previews/test_pesq2_mtlb.m/index.html there are 3 values that can be calculated:

    %    NB PESQ MOS = 1.969
    %    NB MOS LQO  = 1.607
    %    WB MOS LQO  = 1.083

I would expect to get the MOS LQO without downsampling.

Is it intended to always return the NB PESQ MOS? If yes, do you have a reason for that?

Thanks for the wonderful code. In your example, I guess it is for .wav file. But for the audio in .raw, is this function still valid? And what is the correct reading function for .raw file.

Thanks for your help.

Thanks for the useful code.

When I try to run command "python setup.py", there is an error. What is the right command for running setup.py?

Another question is about missing pesq_core module when running init.py. Does this problem fixed after I run setup.py correctly?

Thanks for your help

Hello everyone, If I do not have a clean version of speech . Can I compute the PESQ between the noisy original speech and the enhanced speech? what does that mean ? Best Regards.

first of all, i'm very glad to found this project and thanks for you contribution. but my envirment is python 2.7 and i found you project is depending on python 3+. so how do i make it apply to python 2.7? // this may be supported to python 3+, because when i run 'python setup.py install' and i got some errors : pypesq/pesq.c(21) : error C2079: 'pesqmodule' uses undefined struct 'PyModuleDef' pypesq/pesq.c(22) : error C2065: 'PyModuleDef_HEAD_INIT' : undeclared identifier pypesq/pesq.c(22) : error C2099: initializer is not a constant pypesq/pesq.c(23) : warning C4047: 'initializing' : 'int' differs in levels of indirection from 'char [10]' pypesq/pesq.c(24) : error C2078: too many initializers pypesq/pesq.c(31) : warning C4013: 'PyModule_Create' undefined; assuming extern returning int pypesq/pesq.c(31) : warning C4098: 'PyInit_pesq_core' : 'void' function returning a value pypesq/pesq.c(54) : error C2143: syntax error : missing ';' before 'type' pypesq/pesq.c(59) : error C2065: 'pesq' : undeclared identifier pypesq/pesq.c(60) : error C2065: 'pesq' : undeclared identifier

i found it at: static struct PyModuleDef pesqmodule = { PyModuleDef_HEAD_INIT, "pesq_core", module_docstring, -1, module_methods };

    if (err_info->Nutterances < 1)
    {
        /*printf ("Processing error!\n");*/
        /*exit (1);*/
        PyErr_SetString(PyExc_RuntimeError, "processing error!");
    }

Log print warnings.warn('Processing Error! return NaN........') use older version, i see it stop at conditions err_info->Nutterances < 1 processing error! WHY? but if i change metric="pesq" to metric="" ，training is ok!

I fix the bug the duplicate symbol happens.

Hi vBaiCai! thanks a lot for sharing this. I have been trying to implement PESQ. I was wondering from the code:

from pypesq import pesq ref, sr = sf.read(...) deg, sr = sf.read(...)

what exactly is suppose to be the input to sf.read.

Thank you in advance!

When installing, I get:

Not sure why that's happening, because pesq.h is clearly there. Any help?

Hi Jingdong Li: this is my code : ref, _ = librosa.load(fliepath_ref,sr=sr,mono=True) deg, _ = librosa.load(fliepath_deg,sr=sr,mono=True) pesq(ref,deg)

thanks

Hope for some one's help. Thank you!

Hi everyone. I am asking about the meaning of nan PESQ score. After some successful compute of PESQ score for my speech samples I got the following error for the residual samples
