ptwz / python_wizard Goto Github PK

I was able to use this program to convert a few audio files to LPC data, and I noticed the README.md mentions a playback feature was added, but I can't seem to find a way to activate it in the GUI, how would one go about playing back the LPC data?

Hi, can you make a quick guide on how to execute this files for noobs?

Edit: I downloaded thonny python and added the scipy package, then runned the file python_wizard_gui ( as said by christurnerchris in the issue #18). But still i can't convert the .wav files to LPC streams.

I got this error message in Thonny:

During handling of the above exception, another exception occurred:

How do i Input the wav file

Hi @ptwz
Amazing code btw !
I tried loading the application, i have python 3.9 installed along with spicy. But i keep getting this error when i run setup.py

C:\Users"username"\AppData\Local\Programs\Python\Python39\lib\site-packages\setuptools\distutils_patch.py:25: UserWarning: Distutils was imported before Setuptools. This usage is discouraged and may exhibit undesirable behaviors or errors. Please use Setuptools' objects directly or at least import Setuptools first.
warnings.warn(

Any guidance is much appreciated
Thanks

(If you want to try it with my files, they are here : audio files)

when processing some audio files I have a warning like :

/Users/***pywizard/Buffer.py:99: RuntimeWarning: invalid value encountered in double_scalars
  coefficients[lag] = s / (rmsBeginning * rmsEnding)

when running
python python_wizard.py -u 0.3 -w 2 -S -p -a -0.9375 -m 0.9 -f hex arcb.wav

but the encoding works

sometimes Its also give me this error : (with the file wftatc.wav)

/Users/***pywizard/Buffer.py:99: RuntimeWarning: invalid value encountered in double_scalars
  coefficients[lag] = s / (rmsBeginning * rmsEnding)
Traceback (most recent call last):

  File "/Users/***pywizard/PitchEstimator.py", line 43, in estimate
    subMultiplePeriod = int( sp.floor( (i+1) * estimate / maximumMultiple + .5) )
ValueError: cannot convert float NaN to integer

but here the encoding doen't work.

(these files works fine in BlueWizard)

I noticed that the sound produced with python_wizard are never as good as the one produced by BlueWizard with the same parameters.
Is this normal? I saw the commits in the cleanup branch. Are you working on this issue?

I love to use python_ward because I can batch process a text file, have each of the lines converted to wav (via Say), process them with python_wizard and then directly send the LPC stream to the Arduino via py_serial for an instant quality check.

I was struggling to get python_wizard to work as it was spitting out errors about RuntimeWarning: invalid value encountered in true_divide on the 8kHz, 16bit signed wav file I was trying to read.

I eventually heavily trimmed it so there was no trailing quiet or silent part and that seems to have fixed it and produced output that (with -S option) works in Talkie equivalent code. The results were almost too good, I need a more robotic voice!!

I'll put more details here as I discovered them, either -d for debug or some fiddling around with pdb showed a suspicious array full of zeros and maybe a few NaNs.

It would be great if there were sample sample wavs together with their expected output in the repository. Those could even be part of some simple tests.

You need to install the script library first
I don't know how to put the -f arduino on the end but it has defaulted to Arduino anyway!

It's not obvious what's going on with the current version if you accidentally feed it a stereo wave file:

Traceback (most recent call last):
  File "/path/venv/bin/python_wizard", line 71, in <module>
    b=Buffer.fromWave(args.filename)
  File "/path/venv/lib/python3.X/site-packages/pywizard/Buffer.py", line 32, in fromWave
    assert(max(d2) <= 1)

This issue may help others who search for what this output means.

then it is found by python editors as a python file

When I try to run python-wizard.py, I get this rather cryptic error code:

Traceback (most recent call last):
  File "python_wizard.py", line 71, in <module>
    b=Buffer.fromWave(args.filename)
  File "C:\Users\laure\Documents\python_wizard-master\python_wizard-master\pywizard\Buffer.py", line 32, in fromWave
    assert(max(d2) <= 1)
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

I don't know anything about this error, except that I have already seen this while using the numpy module.

I was converting my own numbers from 0 to 9. I know they already exist it was just a test. All converted but the number nine. I will try to attach it here but first here is the error I got:

Before the error I just tried to attach the wav file and it would not let me. Here is a drop box link to it:
https://www.dropbox.com/scl/fi/po3fjhaz8o53109iprrhn/Nine.wav?rlkey=fzpojpkuvc55ftupp92xe304n&dl=0

After you try it I will remove the link kbut for now it will be up there.

Note I tried this with python 3.11 and 3.8.9
I would rather not go back to 2.x if I don't need to.

I am on Mac with Python 2.7.11

I thought I had raised this as an issue, but it seems to have disappeared.
python3 /home/stephena/python_wizard/python_wizard -S -T tms5220 -f arduino you.wav2 > wavelpc.h
This is the original code in your original instructions, my file names.
But it overwrites the same file, each time you use it.
It should be
python3 /home/stephena/python_wizard/python_wizard -S -T tms5220 -f arduino you.wav2 >> wavelpc.h
which adds the lines to the existing file.
Secondly how do you run repeated command lines like this in python or shell script?
I have 43 wave files to process into one lpc file!

I'm using it to generate my own sound files, but after I play it via arduino and Talkie library the sound if grabled at the end. What am I doing wrong?

Thanks a lot!

Adding 0xFF at the end sometimes helps, but not with every sample. I guess, this is encoding issue?

Any plan to have the audio output from the command line?
It would be useful to help to tweak the parameters with some audio feedback
thanks

analyzing sounds from some old TMS5220 from the Talkie library shows lots of repeats.
I like them because my instruments use them a looping point.

I noticed that the repeat flag is never generated when I process sound with BlueWizardor python_wizard
Is it on purpose or it's just not yet implemented?
