    HI there !!!
    I'm trying to master my track
    I use as a reference tool "T-rackS metering"
    But my track result to have a higher rms than the perceived loudness , how can I only increase the perceived loudness without increasing the rms ?
    I tried with the limiter but without succeeding,
    some help please ?

    IMHO, don't bother about loudness too much. Just try to find a professional mixed/mastered song of the same genre and tried to match the loudness with your song.

    don't quote me on this, but perceived loudness has to do ALSO with the frequencies your song has.
    if your song has a lot of bass but lacks in mid-mid highs, perceived loudness won't be huge. someone once said that we hear much more in the interval of the vocal range. you can easily try this yourself just by boosting some of those frequencies and see how it sounds "louder".

    and yes, as sonic said above, reference is a good thing, but as always trust your ears (well, at least as long as they can hear above 12/13 kHz lol)

    You will have to cut bass and highs, also write the song in the mid register, if you want perceived loudness.
    Your music can be insanely loud in the lows and the highs, but we can't hear in these areas very well.
    The problem with loud music is that you are basically killing even more your sensitivity to these frequencies.
    I'm in my mid 20s and I have friends around my age that have damaged their ears from listening to headphones.

    In most of the cases increasing perceived loudness will result in increased RMS because that's how ear works. However, measuring with TR Meter is not effective anymore. Use a Loudness Units meter (a very good option is Melds Production's MLoudnessAnalyzer) while your song is peaking at -1 dB FS and target -14 LU if you want your track to be streamed (iTunes, Spotify, YouTube) or -10 LU if you prepare a CD master (or Beatport)

    RMS is channel pressure.. a physical interpretation of sound.. how hard it's hittin the cones, etc. If you put a lp filter on a sub bass, roll it off so everything is gone after 10hz, and boost that channel to -6rms it'll be a topic of how you "feel" what you hardly hear at all. You boost a 500hz signal to -6rms it's a topic of way too loud. These two examples describe what perceived loudness is. The perceived loudness meter is very useful for a/b referencing your masters. Popular songs that peak at 0 generally have a perceived loudness near -20 that will jump according to instrument and vocal climaxes. If there's no vocal the average shouldn't fall much lower than -25. That's a nominal level for an instrumental.
