Downloaded the sound from https://sounds-mp3.com/, and the syntax of the playsound was from the official site of it. Still there is no sound played and giving me the below mentioned output of execution.
from playsound import playsound
playsound('C:\\Users\\HP\\Downloads\\0003537.mp3')
output:
python -u "c:\Users\HP\Desktop\python files\hello.py"
I doubt it is a problem with the code, it looks fine.
It might be to do with your speakers or the audio file. Try out a wav and see if that works. Check your path too. I have had problems in the past with files downloaded from the web so maybe record something on Audacity and see if that plays. Try playing the audio file with the default software for your os, does it work?
After I had pip installed pydub and SpeechRecognition, I still can't make the program run successfully although I extracted the files from ffmpeg and specified the folder name bin in the corresponding directory. I tried to find solutions to solve the problem but it sill didn't work after I followed the steps clearly from the web. May I ask what is the good way to read .wav files using pydub AudioSegment?

Make sure that you have ffmpeg http://www.ffmpeg.org/ installed. You can get help from this official page.
Other thing that I can think of is that ffmpeg is installed and is in your path but not in the path of the process using pydub.
If this is the reason for the error, then you can set the absolute path to ffmpeg directly like shown below:
import pydub
pydub.AudioSegment.ffmpeg = "/absolute/path/to/ffmpeg"
sound = AudioSegment.from_mp3("test.mp3")
Give this a try.
Unless I use one of librosa's native 'example' audio files which are in some format '.ogg', I cannot load audio.
Every github issue and SO answer says I need to install ffmpeg. I found a python package called ffmpeg and installed it into my virtual environment. I also found some sort of multi-purpose program called ffmpeg and installed it onto my Windows machine, and added it's location to my PATH variable.
I still get the same warnings and errors that everyone else is getting:
c:\users\wesle\appdata\local\programs\python\python38\lib\site-packages\librosa\core\audio.py:162: UserWarning: PySoundFile failed. Trying audioread instead.
warnings.warn("PySoundFile failed. Trying audioread instead.")

I can find no resolution for this problem despite the number of people asking for help on it.
I don't know what fileformat you are trying to load, but in most cases installing ffmpeg is the solution to this problem. It is important to add the "../bin/" directory to PATH and restart the environment. Using the "set" command from prompt you can check that the current path contains the folder.
Ok, now I am stuck up in converting mp3 to wav. I have seen different answers but i think i would to go for the one of pydub, which i already did using these few lines
from pydub import AudioSegment
AudioSegment.from_mp3("/input/file.mp3").export("/output/file.wav", format="wav")
but when I run the above code, i get the following error

I don't know why it raises this error as i am very sure the file exists. Although i have answers suggesting the installation of ffmpeg, but i dont know if affect the app deployment in any way later on
The pydub module uses either ffmpeg or avconf programs to do the actual conversion. So you do have to install ffmpeg to make this work.
But if you don't need pydub for anything else, you can just use the built-in subprocess module to call a convertor program like ffmpeg like this:
import subprocess
subprocess.call(['ffmpeg', '-i', '/input/file.mp3',
'/output/file.wav'])
This requires that the ffmpeg binary is in a location in your $PATH, by the way.
Edit: With ffmeg, you cannot convert stereo to mono, as far as I know. You can only choose the left or right channel. I'm assuming this is not what you want.
The sox program can convert stereo to mono:
import subprocess
subprocess.call(['sox', '/input/file.mp3', '-e', 'mu-law',
'-r', '16k', '/output/file.wav', 'remix', '1,2'])
This will sample at 16 kHz, with 8 bits/sample, giving you 16 kb/s.
You must go for pydub, it is a great module for operations related with audio files.
NOTE. Do remember to install ffmpeg before you use pydub.
For help regarding installation of ffmpeg, you can use this link.
Then to install pydub just open your command prompt and type
pip install pydub
Then to convert any file from mp3 to wav just use pydub as
import pydub
sound = pydub.AudioSegment.from_mp3("D:/example/apple.mp3")
sound.export("D:/example/apple.wav", format="wav")
The problem is due to the missing of ffmpeg. Pydub requires it to perform the operations of format conversion. To solve the problem, there are 2 ways:
Simply install pydub with conda, not pip (despite the suggestion on Pydub's GitHub page)
conda install -c conda-forge pydub
This should work fine. Reason unknown, possibly due to the compatibility stuff.
The other solution (if you already used pip to install Pydub, and it does not work) is to install the missing ffmpeg package. Here comes another problem. Though we can find a package named ffmpeg on both pypi and anaconda, if we only installed one of the source, we will probably see the error like
In [1]: import ffmpeg
---------------------------------------------------------------------------
ModuleNotFoundError Traceback (most recent call last)
<ipython-input-1-16f5f3b4de71> in <module>
----> 1 import ffmpeg
ModuleNotFoundError: No module named 'ffmpeg'
After several tests, I found that both have to be installed to make the package ffmpeg work (install twice, in other words). Otherwise, somehow python cannot find the package even if it has been installed via either pip or anaconda. So just type
pip install ffmpeg
conda install ffmpeg
Now try to import ffmpeg in python. If there is no error, the problem should already be solved.
NOTE that, manually downloading ffmpeg from FFmpeg website and append the bin path to sys.path might not help with this problem. Similarly, manually specifying the path to the executable of ffmpeg (on Windows it is ffmpeg.exe) might not solve the problem either.
I want to animate some plots with matplotlib. The version I have is the Enthough Canopy distribution (Version: 1.1.0.1371), running in a mac os x 10.8 (Mountain Lion). I have used the FuncAnimation routine from the animation package of matplotlib. My problem comes saving the animation. I want to save in mp4 format:
anim.save('test.mp4',fps=30)
The error I get is:
UserWarning: MovieWriter ffmpeg unavailable
warnings.warn("MovieWriter %s unavailable" % writer)
So I installed ffmpeg via Macports. But I am still having the same error. Do you know how to setup matplotlib in order to recognise ffmpeg? Do I have to change the matplotlibrc file?
Thanks.
EDIT: I have realized that I can manually put '/opt/local/bin' in the PYTHONPATH, but it does not change the PATH in Enthough Canopy. Do anyone know how to change the PATH in canopy?
I had the same problem. My solution was very simple.
Download the binary from here.
Then do
sudo mv ~/Downloads/ffmpeg /usr/bin/
I had success when installing with homebrew:
brew install ffmpeg
After that set up the FFMpegWriter yourself by:
mywriter = animation.FFMpegWriter()
anim.save('mymovie.mp4',writer=mywriter)
I think the solution can be found in the workaround in this and this post.
It seems that the path of the shell is not loaded by matplotlib, and since macports are installed in /opt/local/bin, ffmpeg can't be found.
Either go for the hack described above, try making a symlink in /bin for ffmpeg, or try adding the path to ffmpeg to the python path as suggested in the comments of the second link
