Hi Ismael,

Sounds like you want to increase the 'loudness' without increasing the
peak of the waves beyond their maximum. I am definately no expert in
audio but when I want to make drums sound louder without increasing their
overall waveform amplitude, I use a Puredata patch to do waveshaping. This
distorts the waveform, stretching it upwards so that there is more
power/energy under the wave but the peaks of the wave are the same. I
think that this is actually a form of compression, but as I said, I'm
no expert.
