So I have ~20 song files (mp3/flac) which I what to save as a playlist which I can put into my audio player. Problem is the levels of all the songs are all over the place (my bad, these go back over a decade and I still struggle with setting a consistent recorded lever). So is there a simple application or process to adjust all the songs to the same output level so when I play I don't have to adjust volumne for each individual song?

Any suggestions?

Dan

Hmm ... I'm not sure if either of these help, but I'll throw them out there anyway, just in case.

As a Linux user, I'd normally do something like that with the command line tool 'sox' (Sound eXchange), but I'm not sure if sox is available on Windows.
e.g.:
Code
sox --norm=-10 infile.flac outfile.flac

I've recently use MixBus to mix down some live sessions and realised that it has an 'analyse' option that will report if the output would been various audio standards, e.g., for YouTube, Spotify, Soundcloud, Deezer, CD, etc... That would, though, mean importing them, adjusting, analysing and exporting, which is much more work than I presume you want to do.

Hopefully a better answer will come along soon.

Dan, Audacity has a Normalize function. The price is pretty good too wink

( I generally set the level of my songs to -3db )

mp3 gain appears to have done the job for all the mp3 files in the folder as a single batch process. A big help thanks.

Dan,

Reaper will also do the job for you. Under the File menu, there is an item called "Batch file/Item converter". This will allow you to normalise using LUFS. LUFS tends to give better consistency between volumes than simple peak normalisation. Online sights such as Soundcloud normalise uploads using LUFS set to around -15.

If you are still getting volume discrepancies between tracks, it would be worth trying Reaper and LUFS. When I tried it just now, Reaper converted mp3s to wav before normalising and the normalised end result was a wav file.

The Reaper idea is good for a lot of files. But you would have to use something like audacity to catch convert back to MP3.

If it is only 20 files I would just normalize all in audacity. -.3 is a good setting. Kind of loud but not too much, at least to me.
