Something I'd love to see in KMPlayer is Replay Gain.

Please have a read about it here: [Only registered and activated users can see links]

Replay Gain is one suggested way of smoothing out volume fluctuations when you play your digital music files, without affecting the audio information stored in the files.

Simply put, a Replay Gain tool analyses the audio in a digital music file and then decides how much louder or quieter that music file ought to be to achieve a standard volume. Then it writes this value, the gain, as a small piece of metadata to the music file. Meta data is just text that gets attached to the file alongside the audio, such as the metadata that describes the artist and track name.

Then a music player that supports Replay Gain can read the relevant piece of metadata and alter the volume of playback for that track. This means that you don't need to be constantly reaching for the volume dial on your speakers every time a loud album follows a quiet album, and vice-versa.

As a sound engineer myself, this really means something. If this becomes a standard, then no longer will you have to squeeze and compress the life out of tracks in the mixing/mastering stage and supreme digital quality can actually be harnessed!

Please spread the word

I think Replay Gain is not suitable for video player which requires mostly a realtime sound processing and the mechanism of Replay Gain is inefficient for the realtime digital signal processing too.
