Hello,
1 - Find where the files have been installed. The easiest way to find the project folder is currently to de-install pianoputer, without actually removing it (press no)

As shown in the image above the project folder will be displayed.
use a command prompt to go to that location
In this example it will be something like c:\users.....\appdata\roaming\python\python311\scripts
This folder will be different for each users and the location might also be in the window Program file folder depends if
you installed Python for all users or not.

So change the path accordingly

C:\>cd c:\users\yoyob\appdata\roaming\python\python311\scripts\

2 - type the following to get to the source file

cd ../site-packages/pianoputer

Once you are in the right folder and can see the file pianoputer.py
edit the file with Python or any other text editor and do the following changes
e.g:

notepad pianoputer.py

At line 103 and line 106 in file pianoputer.py
Change

            if channels == 1:
                sound = librosa.effects.pitch_shift(y, sr, n_steps=tone)
            else:
                new_channels = [
                    librosa.effects.pitch_shift(y[i], sr, n_steps=tone)
                    for i in range(channels)
                ]

to

             if channels == 1:
                print(y, len(y))
                sound = librosa.effects.pitch_shift(y=y, sr=sr, n_steps=tone)
            else:
                new_channels = [
                    librosa.effects.pitch_shift(y=y[i], sr=sr, n_steps=tone)
                    for i in range(channels)
                ]

• Don't forget to save after changing the lines above (CTRL+S)

Then run the source code

python pianoputer.py 

Once this has been changed into the project source code and reloaded to PIP pianoputer will works without applying this fix

def pitch(data, sampling_rate, pitch_factor=0.7):
return librosa.effects.pitch_shift(data, sampling_rate, pitch_factor=pitch_factor)

def get_features(path):
#set the duration and offset
#librosa.load takes audio file converts to array and returns array of audio file with its sampling rate
data, sample_rate = librosa.load(path, duration=2.5, offset=0.6)

#get audio features without augmentation
res1 = extract_features(data,sample_rate)
result = np.array(res1)

#get audio features with noise
noise_data = noise(data)
res2 = extract_features(noise_data,sample_rate)
result = np.vstack((result, res2))

#get audio features with stretching and pitching
#rate = 0.8
new_data = stretch(data)
data_stretch_pitch = pitch(new_data, sample_rate)
res3 = extract_features(data_stretch_pitch,sample_rate)
result = np.vstack((result, res3))

return result

when i call this function from get_features this gives the error "TypeError: pitch_shift() takes 1 positional argument but 2 were given"
Anyone plz help

[yoyoberenguer]

hello, can you provide the method extract_features?
This method is missing from your code and I cannot reproduce without it
Also worse changing the method from

def pitch(data, sampling_rate, pitch_factor=0.7):
     return librosa.effects.pitch_shift(data, sampling_rate, pitch_factor=pitch_factor)

to

def pitch(data, sampling_rate, pitch_factor=0.7):
    return librosa.effects.pitch_shift(data, sampling_rate, n_steps=pitch_factor)

Kind Regards

Thank you for this helpful information
