Audio Normalization
#1
Hello Friends,

Can anyone suggest me the way to do audio normalization? I am on Windows 10.

Firstly, you can not do this within MSP, it will have to be done using an external program.

Secondly, you have to understand that 'normalising' an audio file merely increases it's level such that the peak level is at 0db (or whatever peak level you choose).  If that's what you need to do, then fine, but what most people need is to make a series of tracks play at the same relative level.  If you 'normalise' a series of files, their relative volumes will still vary - you need to to do something known as RMS (root mean square) balancing, this makes all the files play at the same relative volume.

There's a ton of programs around that can do this, from free to expensive.  You can search for them easily enugh, but I'll give you two to start you on your way.  For .wav files, volume balancer - http://www.delback.co.uk/volbal/ - and for MP3 files, MP3Gain - https://www.filehorse.com/download-mp3gain/ .

Will this method be able to handle what you say?

Audacity is free Windows software:

Audacity is is bit of a sledgehammer to crack a nut. 

More to the point, the normalise function merely sets the peak level (as I described in my initial post) and if the OP wants to prepare his recordings so they play at the same perceived volume, then Audacity is not the right tool to use.

Even IF Trotsky26 wants this or that be sure Audacity can do your compression/RMS too:

If the desired end result is a series of tracks which all play at the same volume (thus avoiding having to change the volume control for every new track) then the RMS average of each track needs to be the same - compression is not the way to achieve this and as far as I am aware, it's not a function available in Audacity.  

Of course, since many modern recordings are compressed to within an inch of their life anyway ("louder is better") it's not something that needs to be done as often as it used to be.

Please let us know how to average audio without calling it RMS.

I'd be happy to help, but I'm not sure I understand the question?
