[aubio-user] Using aubio 0.4.0 from python (windows)

Wed Jan 1 20:52:45 CET 2014

And here the attached log file I mentioned. :)

> Hi and happy new year!,
>
> Great! now "configure" and "build" finished succesfully also for me
> (except for "test-delnull.exe", which crashes). I also installed the python
> binding with "python setup.py build", and it did it successfully I think.
> However, I wasn't able to configure the path in windows (python scripts
> always reported that libaudio-4.dll was missing), so I directly copied such
> dll to the same folder as the running python script, and it seemed now it
> does not report such error.
>
> Unfortunately, I still have problems at running the python demos and some
> python tests (run_all_tests crashed at some point, so I run them
> independently). Specifically, I have problem with the following python
> tests scripts: "test_specdesc.py", which directly crashes, and
> "test_filter.py", "test_filterbank_mel.py", "test_peakpicker.py" and
> "test_scale.py" that reported some problems (attached .txt file).
>
> Moreover, when running the demos with a a 44100Hz mono 16-bit WAV file of
> 134KB called test.wav, I have this type of problem (I didn't try all demos
> though):
>
> e.g.,
> "(...)\aubio\python\demos>python demo_pitch
> .py test.wav 44100
> AUBIO ERROR: failed creating aubio source with test.wav
> Traceback (most recent call last):
>   File "demo_pitch.py", line 19, in <module>
>     s = source(filename, samplerate, hop_s)
> StandardError: error creating object"
>
> How could I fix this problem?
>
> Thank you very much!

> Greetings,
> Emilio.
