What is the difference between "filename" and "name_file"?

[niklas1102]

Is there a difference between "filename" and "name_file"? For example, if I want to use
get_harmonic_change(filename: str, name_file: str, hpss: bool = False, tonal_model: str = 'TIV2', chroma: str = 'cqt', blur: str = 'full', sigma: int = 11, log_compresion: str = 'none', dist: str = 'euclidean')
What is the "name_fiele" here?
There is an explanation, but I didn't quite understand it. Can anyone explain this to me?
Thanks in advance

Hi there!! @Androidismyhobby

Thank you for using my code! (It was part of my bachelor thesis last year)

Just out of curiosity, what are you going to use it for? :D

if your file to compute is ´please_please_me.wav´. Then, filename='please_please_me.wav' and name_file='please_please_me´.

filename is the name of the file to be processed. And name_file is the name of the files that are generated to reduce computational cost. The reality is that this code was part of a larger distributed system and namefile was not the same as filename. But you are right that the naming doesn't help to understand. I can change it to in_file, out_file hahahaha

Have you installed the vamp plugins? (to make nnls work)

Have you read the paper?

Thank you so much!

Hi, @PRamoneda ,
Thank you for the quick and good explanation.
I recently came across your library and it really is the only good HCDF library out there that I could find. Thank you very much for publishing it on Github and I'm glad I came across it. At the moment I'm still trying things out a bit and I just wanted to see what one can do with it, because I'm interested in music and computer science and also currently study this. I have already installed the vamp plugins, but I haven't read the paper yet, but I definitely plan to do so ;-)

Again: Great library and really a stroke of luck for me. And thanks again for the explanation :-)

Hi, @Androidismyhobby

Thanks for your kind words :)

My background is also in computer science and music (piano performance). Currently, I am studying this master: https://www.upf.edu/web/smc.

There are a lot of opportunities in this field. I also recommend you this library if you are interested in building models from data: https://github.com/mir-dataset-loaders/mirdata (I am collaborating in the development too xd)

What university are you from?

[niklas1102]

Hi, @PRamoneda ,
Funnily enough, I study almost the same thing as you in the UK (https://www.gold.ac.uk/ug/bmus-bsc-electronic-music-computing/), even if I'm originally from Germany. I'm only here in the first semester, but for me it really is the most exciting subject that you can study. But I still have a few years ahead of me xd.

Thank you very much for the tip from your library. I will definitely take a look at it. Sounds very exciting and is exactly my "taste" ;-)
I was really surprised at first when I was looking for such modules because I found almost nothing, but apparently there are quite a few ...

Can I ask you one more thing about using your HCDF library? I'm sorry, I hope I don't annoy you with this:
Am I using this correctly: HCDF.harmonic_change ("please_please_me", "please_please_me.wav", False, "TIV2", "cqt", "full", 11, "none", "euclidean")
But unfortunately I always a list-index-error:

Traceback (most recent call last): File "<stdin>", line 1, in <module> File "C:\Users\Kinder\Downloads\HCDF-master\HCDF-master\HCDF.py", line 685, in harmonic_change check_parameters(chroma, blur, tonal_model, log_compresion, distance) File "C:\Users\Kinder\Downloads\HCDF-master\HCDF-master\HCDF.py", line 206, in check_parameters chroma = get_parameters_chroma(chroma)["chroma"] File "C:\Users\Kinder\Downloads\HCDF-master\HCDF-master\HCDF.py", line 173, in get_parameters_chroma return {"chroma": rows[0], "sr": int(rows[1]), "fr": int(rows[2]), "off": int(rows[2]) // int(rows[3])} IndexError: list index out of range

Did I make any mistake with the input? As I said, I'm still trying a bit and I'm not very experienced with such modules so I hope I haven't made some stupid mistake ;-)

[PRamoneda]

I hope I don't annoy you with this:

I am always asking to everybody! Don't worry!

Ok, try to download other time the library! I have removed some little problems I generated when I extracted this part of code from the whole system.
BTW, filename is the file path from the python code:
'./audio_files/07_-Please_Please_Me.wav'
and name_file only the name without the extension '07-_Please_Please_Me'

if I execute this code:

if __name__ == '__main__':
    onset, hcdf, winows_size = harmonic_change('./audio_files/07_-_Please_Please_Me.wav',
                                               '07_-_Please_Please_Me',
                                               chroma='stft-44100-2048-4',
                                               hpss=True,
                                               tonal_model='TIV2',
                                               blur='full',
                                               sigma=17,
                                               distance='euclidean')

    print("chord changes", onset)

the screen output is:

Perfect. It works. Thank you very much for your efforts and your support.
I have to say, I'm pretty excited that it works :-) Now I'll have a fun time trying it out.

Thank you very much
