Flac Volume level

[kirkmc]

Anyone have/know a program that will report the audio levels of a flac file?
I know foobar offers replay gain levels but the results don't seem to be able to be exported, nor show the tracks full filename.
Thanks for any info.

SoX should support flac, ffmpeg will for sure support flac and other types.
Checking audio level in ffmpeg is very common problem:

Hi Pandy the 2nd link looked promising but instructions are a bit mickey mouse
Detect the audio file volume with ffmpeg.
Require tools
ffmpeg: Official site, Download
How to use
Download ffmpeg from link
Extract the ffmpeg.exe from zip package and copy to the directory contain the audio file
Copy the volumeDetect.bat into the folder. (Just make sure the bat file and ffmpeg.exe are in the same directory)
The first link doesn't offer a zip file and the second link is a 404.
I have an ffmpeg.exe that's 35,358 KB but no volumeDetect.bat. Has anyone got that ? Thanks.

I did manage to open the ffmpeg .7z file but it didn't contain any volumeDetect batch file mentioned as needing.

Audacity will show the audio levels of a flac file but doesn't do in batch mode.

Or possibly Ocenaudio, gives peak and average RMS

You need to create batch (bat or cmd) file by yourself however i can provide some batch as example:

@setlocal

@REM Where to Find ffmpeg
@set FFMPG=C:\FF
@set PATH=%FFMPG%;%PATH%

@set fname=%~1

@ffmpeg.exe -vn -sn -dn -y -hide_banner -v 32 -i "%fname%" -filter:a volumedetect,astats -f null - >NUL  2> "%~n1_vol_stat.txt"

@endlocal
@pause

result of ffmpeg will be file with name your 'audiofile_vol_stat.txt' and you can see example of action for above filter bellow:

IMPORTANT:
I assumed that your ffmpeg.exe will be located on disk C in folder 'FF' - you can easily change this assumption by editing one of the batch lines - this one:

@REM Where to Find ffmpeg
@set FFMPG=C:\FF

modify

@set FFMPG=C:\FF

to real folder where ffmpeg.exe is located line beginning with REM is commentary line to emphasize below line with ffmpeg.exe location i.e. if your ffmpeg.exe is located on disk D in folder named 'myffmpeg' then line:

@REM Where to Find ffmpeg
@set FFMPG=C:\FF

shall be replaced with line:

@REM Where to Find ffmpeg
@set FFMPG=D:\myffmpeg

how to create batch file?

Simplest way:

- run notepad
- copy and paste (CTRL+C, CTRL+V) above example to your notepad, save edited text as 'nameyoulike.bat' or 'nameyoulike.cmd'

now you can test audio level in your file with drag & drop in Windows as your batch file is considered to be application

beware, i see that drag & drop seem to be inactive in win10/11 - if this is your case consider to use batch from command line i.e. open cmd and write 'nameyoulike.bat' or 'nameyoulike.cmd' and after 1 space place filename you wish to examine (to reduce effort write few first letters and press TAB key so commandline should complete rest) alternatively activate drag & drop.
Personally i recommends some file commander such as splendid Total Commander so working with files is way more efficient than ineffective Windows (yes i'm old, i grow with xtree, norton commander and their heritage)

Thanks for any info.

A bit of a late reply, but for the record, you'd need the foobar2000 text tools component. After you've added it to fb2k find it's page in preferences.
