Total Commander

Do Media player support ReplayGain?

There is a Equalizer, BassBoost, Loudness Enhancer and stereo virtualizer effect.
Maybe Loudness Enhancer can match with your requirement.

As far as I know there is no Replay Gain functionality implemented.
Btw, if you want to hear music on your device, better use dedicated player software...

@matixx:
Replay Gain, in contradiction to Loudness Enhancer, will increase the volume of a song dependent on a preset "dB" value within the metadata of the audio file to achieve the same perceived loudness of all those files, i.e. most of the tools that calculate this Replay Gain use a standard target loudness of 89dB and then store the "difference" within the metadata of the mp3 file.
According to this Replay Gain data, the player will then individually increase the loudness of each and every audio file to achieve the same loudness for all audio files, whereas the Loudness Enhancer only increases the loudness to a certain level per se (absolutely).

In essence: LE only makes music louder independent from the audio's initial volume and independent from all other audio files, RG increases the loudness to the same pre-defined level for all audio files that have a calculated Replay Gain (if calculated with the same standard target loudness).

It does not support ReplayGain. Try Loudness Enahncer if it works for you.
