avconv output_volume option - trying to understand the man page

I'm trying to increase the volume of my input .wav file by means of the output_volume option within the avconv command. I would like to increase the volume by 6 dBs similarly as demonstrated in the man page.

I have my command in a script format

for i in *.wav; do avconv -i "$i" output_volume=volume=6dB:precision=fixed "$i{%.*}".mp3;done

But I receive the following error. I see many search results pertaining to FFmpeg but I not helpful towards avconv

Unable to find a suitable output format for 'output_volume=volume=6dB:precision=
fixed'

The general sytanx from the man page is:

avconv [global options] [[infile options][‘-i’ infile]]... {[outfile options] outfile}...

I having trouble interpreting the documentation..

Solution

  • Try something like this:

    for i in *.wav; do
    avconv -i "$i" -af volume=6dB:precision=fixed "$i{%.*}".mp3
done
