  • How convert High bitrate mp3 to lower rate using ffmpeg in android

    23 mars 2018, par Android Team

    We want to convert 320kbps mp3 file to 128kbps mp3 so currently we are using below ffmpeg command but its not working.

    ffmpeg -i input.mp3 -codec:a libmp3lame -qscale:a 5 output.mp3

    Result :-the output bitrate same as input mp3.

    And we are following the FFmpeg Encoding guideline for that here is the link :- https://trac.ffmpeg.org/wiki/Encode/MP3

    so please suggest any solution.

  • ffmpeg clean all noise background silences in a poscast

    23 mars 2019, par fireDevelop.com

    I have hundreds of podcast without music, just the voice and the room silence.
    In the silences, I have many clicks, respirations, etc...
    I need to clean all silences with a script, keeping intact the voice.

    In this picture you can see my dirty silences

    And here the result I want in all my audios

    When I use some scripts of sox. I don`t get the result I spect because the voice is affected by the script, the room-silence disappear and some clic still in the silences.

    Then in order to keep intact the voice, I want to do this :

    1. Delete all the silences longer than 3 seconds.

    1. Split all the audio and silences with in a sequence numbers. ie. :

      • 001-Silence-2.0seconds.wav
      • 002-voice.wav
      • 003-Silence-0.25seconds.wav
      • 004-voice.wav
      • 005-Silence-0.75seconds.wav
      • 006-voice.wav
      • ...
      • ...

    1. Before, run the script I created manually many files with silences of diferents silences I will use :

      • myManuallySilence-0.25seconds.wav
      • myManuallySilence-0.50seconds.wav
      • myManuallySilence-0.75seconds.wav
      • myManuallySilence-0.1seconds.wav
      • myManuallySilence-1.25seconds.wav
      • ...
      • ...
      • myManuallySilence-2.50seconds.wav
      • myManuallySilence-2.75seconds.wav
      • myManuallySilence-3.0seconds.wav
    1. the script will check the dirty silences duration and replace by the files myManuallySilence-x.xseconds.wav
    1. merge all files in one wav file, with the original voice and all the silences cleanned.

    At the moment I have only this script :

    # get the path of Adobe Audition and add timestamp in the output 
    
filename
    
fileName=out
    
current_time=$(date "+%Y.%m.%d-%H.%M.%S")
    
newFileName=$fileName.$current_time.wav
    
#yourPathAPP=/Applications/Adobe\ Audition\ CC\ 2019/Adobe\ Audition\ 
    
CC\ 2019.app
    
yourPathAPP=/Volumes/6TB/Applications/ocenaudio.app
    
# # First denoise audio
    

    
# ## Get noise sample
    
 ffmpeg -i in.wav -vn -ss 00:00:00 -t 00:00:01 noise-sample.wav
    

    
# ## Create noise profile
    
 sox noise-sample.wav -n noiseprof noise.prof
    

    
# ## Clean audio from noise
    
 sox in.wav $newFileName noisered noise.prof 0.50
    
# # Split audio by noise
    
 sox -V3 $newFileName output.wav silence 1 00:00:02.000 - 80d 1 
    
 00:00:02.000 -80d : newfile : restart
    

    
# ####### (these settings worked for my computer mic - maybe we need to 
    
finetune them later) #######

    Is getting all the voice in separate files like this :
    output001.wav
    output002.wav
    output003.wav
    output004.wav
    ...
    output00x.wav

    Please, any suggestion will be appreciated.
    Thanks so much in advance !
