• Why PyAudio doesn't read 'mp3' ?

  22 octobre 2020, par freshITmeat

  I tried to read file that I give with absolute path.
When I run my code first that I see is this message :

  


  D:\prog\datascience\anaconda\lib\site-packages\pydub\utils.py:170: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work
  warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)


  


  I tried this :

  


  PATH_TO_FFMPEG = 'D:\\prog\\ffmpeg-win-2.2.2\\ffmpeg.exe'
pydub.AudioSegment.converter = r'D:\\prog\\ffmpeg-win-2.2.2\\ffmpeg.exe'


  


  And I separately installed ffmpeg with pip. But it didn't help.
When I try this :

  


  raw_sound = pydub.AudioSegment.from_mp3(file=track_path)


  


  where track_path is correct absolute path generated automatically.
So I got this this error :

• ffmpeg showspectrumpic fscale=log not rendering Right audio channel

  8 janvier 2021, par hjeannin

  I am running these two command and getting surprising result on the second one.

  


  The first command produce (fscale=lin) :

  


  ffmpeg -i stereo-test.mp3 -lavfi showspectrumpic=s=600x600:mode=separate:fscale=lin:scale=log spect_lin.bmp


  


  spect_lin.bmp

  


  but the second command produce (fscale=log) :

  


  ffmpeg -i stereo-test.mp3 -lavfi showspectrumpic=s=600x600:mode=separate:fscale=log:scale=log spect_log.bmp


  


  spect_log.bmp

  


  Sadly on the second image, the right channel is missing and I cannot figure out why.
Any idea or suggestion would be awesome :)

  


  Thanks !

  


  PS : You can find my test file here : stereo-test.mp3
