I'm not familiar with python, but it seems that after python 1.11 float indexes cannot be used to access arrays or something. And this happens in script with following trace:
INFO:Loading data...
INFO:Generating wave...
Traceback (most recent call last):
File "./melosynth.py", line 400, in
args.square, args.useneg)
File "./melosynth.py", line 315, in melosynth
freq_series = np.ones(nsamples) * f_prev
File "/usr/lib/python2.7/dist-packages/numpy/core/numeric.py", line 192, in ones
a = empty(shape, dtype, order)
TypeError: 'numpy.float64' object cannot be interpreted as an index
Can be fixed replacing line 308, but I'm not sure if this is the correct way to fix it:
nsamples = np.round((t - t_prev) * fs)
nsamples = int(np.round((t - t_prev) * fs))
Hi Justin,
I am having a try in your melosynth python module on a Ubuntu 14.03 32bits, with python 2.7 Anaconda distribution. When running the code to synthesize a .csv exported from Sonic Visualizer with Melodia it gives me:
Traceback (most recent call last):
File "melosynth.py", line 399, in
args.square, args.useneg)
File "melosynth.py", line 345, in melosynth
signal.extend(samples)
MemoryError
Any idea on whats going on?
Thanks in advance
