Dear all,

I'm trying to normalize an audio file.

using the effect preset '-ev' gives me the maximum gain which can be applie=
d before clipping.

But the manual states that this value can be used to amplify the signal usi=
ng the '-ea ' preset.

I want to make a script which passes the value from the '-ev' output into '=
-ea', so:

ecasound -i Test.wav -ev -o:null

...some code from the script...

ecasound -i Test.wav -ea:<percentage_based_on_ev> -o Test2.wav

I can get any value that is listed in the output of '-ev' using grep and th=
en pipe it into a variable.

I get the impression that I have to make a calculation from gain (in dB I p=
resume) to a percentage, before I can pass the value into '-ea'.

Is this correct or can I somehow pipe the output of '-ev' directly into '-e=
a'?

Kind regards,

Hans
