ffmpeg clean all noise background silences in a poscast
23 mars 2019, par fireDevelop.comI 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 :
- Delete all the silences longer than 3 seconds.
-
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
- ...
- ...
-
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
- the script will check the dirty silences duration and replace by the files myManuallySilence-x.xseconds.wav
- 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.wavPlease, any suggestion will be appreciated.
Thanks so much in advance ! -
Why the result of FFmpeg capture process has no audio to create a webm file ?
23 mars 2019, par RAMThe result of my bellow
FFmpeg
command has no audio (is silent) :ffmpeg -f gdigrab -framerate 30 -i desktop -video_size 720x480 -c:v libvpx-vp9 -c:a libopus -b:v 1M -b:a 128K -auto-alt-ref 0 -crf 10 -preset ultrafast output.webm
But this one has audio :
ffmpeg -f gdigrab -i desktop -f dshow -i audio="Microphone (4- High Definition Audio Device)" output.mkv
- How should I capture as
webm
file by usinglibopus
orlibvorbis
? - What is the problem in my first command ?
