There are basically two important settings: Buffer Length and the Max Volume Level.

Buffer Length:
To determine the loudness of a section of a song, an average volume of N samples will be computed. N is the Buffer Length.

Max Volume Level:
For any section of a song, if the average volume of N samples exceed V, the song's volume will be normalized to V. V is the Maximum Volume Level.

The above two settings are the same settings you see in VLC's preferences. Long Buffer Length allows short variation in volume to go through while short Buffer Length made the volume level throughout.


How to use this feature to achieve "Automatic Volume Control"?
The goal is to set the Max Volume Level low enough so that the softest song in your collection is unaffected by this feature. That is, say the softest song in your collection has the loudness of "1.6" and you set the Max Volume Level to 1.6. What this does is for your other songs, their volume will be normalized to 1.6 and hence the volume when playing any song in your collection is "1.6". You would then tune your mixer/amplifier so that a volume of "1.6" sounds good for your setup.

Notes:
This feature can be enabled/disabled at anytime and its settings can be changed at any time. However, it will only take affect starting on the next song. As with other graphic settings, "replay" is not considered the "next song". Next song is the next song on the queue or if the queue is empty, the next song you'll add to the queue.

Recommended Settings (Presets will be made available in v1.5.037):
For most songs, N=10 is optimal. For trance/remix music where the are high-base beat in between soft and silent duration, computing an average over 10 buffers sometimes allow loud bass beat to go through (since it has 9 silent buffer and 1 loud buffer, the average is still low). Allowing some loud beats to go through will cause noticeable imbalance in the overall volume.

Can't wait to get back home to test this out.

Anyone able to tune the settings to best fit for Vietnamese karaoke? Based on my test on my stereo system (varies greatly from my 2watt monitor speakers), this setting seems best:

Buffer Length: 10
Max Vol Level: 2.2

If you have more low quality songs (like Youth Entertainment), decrease Max Vol Level down to 1.9 to 2.1 range to get more normalized.

Volume aka V has to be up high like 5 - 7 ?

No, it's actually the opposite. If you want to be more normalized (more constant volume for all songs), lower the V value. See my recommended settings chart.

Higher V gonna of course sound louder but that is not the point. The point is to have "constant" volume doesn't matter which song is being played. Need to pick a different low-quality song if your song sound louder as V is reaching 6. This means the song you picked is fine, it has no volume issue. You want to pick a soft song to fine tune your settings.

You can set it up to play random songs and listen through a few consecutive songs to see the overall volume. Think about "audio normalization" as "socialism". You want to take money away from the rich and give to the poor so that everyone in the society has pretty much the same wealth! [laugh][laugh]. What this mean is some people gonna loose money (rich people or loud song). Lower a high quality song volume seems bad at first but remember you are making this adjustment at the sound-card out level. Your final adjustment is at your mixer so you can fine tune your mixer so that when near-constant sound comes out at the sound card, amp it so that it sound best for your system. The net effect is that you have near-constant volume for all your songs and they sound great on your system.
