Read and Visualize Audio Files in Python (librosa module)
Вставка
- Опубліковано 10 січ 2019
- This Python video tutorial show how to read and visualize Audio files (in this example - wav format files) by Python. For this reason librosa module is using.
In addition to that matplotlib library is a perfect tool to visualize amplitudes of audio files. Glob module is used for reading audio files from working directory.
Matplotlib - matplotlib.org/
Glob module - docs.python.or...
More reading about librosa in official documentation: pypi.org/proje...
In simple words - LibROSA is a python package for music and audio analysis. It provides the building blocks necessary to create music information retrieval systems.
Dataset source: www.kaggle.com...
I will try to develop this topic (audio files analysis) in the context of Machine Learning. For example classification task to identify the male or female voice is on the audio.
Best regards.
Vytautas.

This is great Vytautas, I was looking for a solution to import multiple audio files at once and as I don't know much of python I was very lost. Glad you posted this content!
I'm glad that helped to you!
@@DataScienceGarage you never went ahead posting more on dealing with audio files did you? I couldn't find it
nice video, I would love to see more music information retrieval related videos with machine learning
you should also check this video: ua-cam.com/video/oGGVvTgHMHw/v-deo.html if you haven't already
@@danny_p466 That's cool. Thanks for sharing!
*HUMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM*
HAHAHAHAHA
Make that the subtitles please!
This was still mad helpful in 2021! thanks!
Thanks a lot for such feedback! :)
great video dude, help me with this ....if i want to print the fourier transform of each of song , what i can do ?
Very good, I'm very happy to be able to get this video. You can increase your material about signal processing and voice recognition.
because I really need it. Thank you very much, from #Timor_Leste...
Thanks alot.😁
Thanks for watching!
Nicely explained, hope to see more such videos. If possible can you show how to mix noise files with audio files using 'for loop' and Librosa
Hello Mr. Vytautas,
Greetings,
Its so glad being a subscriber your you-tube channel and videos are very useful for me.
Please upload the video for the audio file analysis such as remove the noise, filtering and voice recognition in the audio file.
Thanks in advance
Hi, good video! Also you can plot all the graphics in 1 image using the .axs in a matrix format .
Yep, of course we can do it :)
does it only work on wav format files? what about mp4,mp3,aac files?
Cool! Thanks a lot for this video! Great help for my research in MER
Good luck with your projects!
Thank you so much.I got a lot of help with this video. Sir, can you upload a video about calculating "Persentage of voice similarly score?”
I will be very grateful to you.🙏
yess, need it desperately please upload another one regarding that
Thank you Garage for your useful video. I look forward to seeing your next videos about classification task to identify the male or female voice. It would be great if you extract the features and train this file with CNN. I hope you can send me the related link of your videos soon. Thank you again.
I wanna write a simple code that monitors the audio output your speakers basically and when a certain audio with a certain frequency is being played the script will press a button. Is it possible?
in the time variable why did you divide range by frequency
how to find the number of samples for each audio file..
I need help. I have followed the steps correctly from the start, but why is the error "name 'glob' is not defined" still not resolved? Thank you
Very helpful, thanks for making this
Thanks!
how to save the images result in a file sir
How would we animate the graph while the sound is playing? Thanks
I applied the code but it keep told me ValueError: x and y must have same first dimension for sentence ax.plot(time, audio)
Very good
Great deed thank you very much!!!, can you do the next part soon?
how to set the directory? data_dir= for any location ?
Yes, exactly, you can change data_dir to any location on your machine to grab files you want.
@@DataScienceGarage thank you, I mean how to set it? what is the format please
@@DataScienceGarage for example, if my *.wav is in D:\user\sound\wav folder, I should write data_dir='./sound/wav'? or './user/sound/wav'?
@@DataScienceGarage there is no error for my code, but the len() result is 0.
@@ssbian9520 'D:\user\sound\wav'
Just copy the address from the address bar of your folder.Using ./ may go to the default directory and may be D:\user is not your default directory.Hope this helps
Can anyone please help how I can implement modulation techniques like ASK, PSK, FSK in python?
my import librosa line is returning No module named 'numba.decorators'. Is this module deprecated?
name glob is not defined error is constantly appearing. kindly help
thank you. that code works)
Hope it's useful. Thanks! :
Me salvaste!!!! gracias!!
You are speaking of audio processing but didn’t remove the hum. Hummm..
Hummmm....
Very helpful
How can I save these files as csv?
How to convert mp3 files into wav format??
Sir your guide on spectrogram?
Thanks a lot !!!
Thanks for watching! :)
please sir, make video on audio files comparison in latest python version(3.8.1)
I loaded only 15 audios out of 100, then I got the error. How to download all the files?
Sir, i want contact with you.. Please help me. I have a Python code but modules line off 😢😢 please fix it
Thank you very much. But can I ask you something, How to save all plot in one file?
I would like to know the same thing
plt.savefig('plot.png', dpi=300, bbox_inches='tight')
with dpi = image resolution
and bbox_inches is optional
i have installed librosa still it is showing module not found can you please help me
Did you installed librosa on your active environment? Type !pip list in your notebook to be sure that librosa is in the list.
thank you for your help but now it is showing sndfile library file not found ,m using jupyter
How did u install librosa in Jupyter notebook? I am getting error.... I have used both pip install librosa and conda install
pip install librosa in terminal should have worked, but if it still doesn't, you can just search up librosa online and download it from the python library.
@@garimaprabhakar6417 I found solution for the issue & I was able to install librosa....thank you for the reply!
Hello, I was wondering if you could help me with my project, I really need some guidance. Is there any way we can talk?
could you do another example teaching about library resources?
I will check what I can do for this. Thanks!
len function is not working in at all. I have tried numerous times. Only output is zero
Hmm, and you have followed all previous commands?
@@DataScienceGarage Thank you, i figured it out
I was working in Pycharm and it was not accepting ./Desktop___ as the address for the directory, rater C:/User/ etc etc. No idea why it didn't throw an error though.
Anyways, thank you for concern and such a good video
plz help:
name 'glob' is not defined
use:
import glob
RIP earphone guy
Video is very hard to follow on a tablet screen. Font is too much small and you wasted a lot of space on the sides of screen. Think about it next video. Thanks.
Holy noise floor on ur voice recording
Yep, in that time I did not had a normal mic.. :)
@@DataScienceGarage that 50/60 hz is pummeling :D
are you from Russia?
No. Lithuania.
@@DataScienceGarage Ok thanks!
I have created another one video demonstrating simple use of glob module: just how to read external files (2 simple methods) some time ago: ua-cam.com/video/1nc5Sju8FVU/v-deo.html
I get sampling frequency half of the original. For 44100 I get 22050
русский?))
WTF is that annoying sound?
Okey, played in my shitty speakers instead of my headphones, that background noise is less aggressive
Anyway, great video
Thanks! :D
