'Gstreamer: Is there plugin to increase audio volume of an audio source

As above. Want to artificially increase the loudness of a microphone recording of live scene. Have used the following plugins volume

 pulsesrc volume=8.0 \
    ! audioconvert \
    ! audioresample \
    ! volume volume=1.0 \
    ! audio/x-raw,rate=8000,channels=1,depth=8,format=S16LE \
    ! filesink location=record.wav

Have also tried audioamplify but seem like both have the raw recorded volume as the upper limit in loudness

Thanks for your help

The volume property of the volume element has a range from 0.0 to 10.0 while 1.0 represents 100% volume.
