Dymamic Range Control?
« on: November 16, 2010, 04:46:19 pm »

At home I would like to play music at its full dynamic range, especially the classic pieces.

But late in the night or in the office, it would be nice to be able to reduce the dynamic range.  I think the FM stations do that to avoid overloading their transmitters.  Pop releases use it to make the recording sound "louder".

With Foobar2000, I use vlevel which is not elegant but works.  Does MC 15 support this feature natively or through a plug-in?

We had a pretty decent DSP to do this many years ago, which was used mostly for volume levelling purposes.  We retired the DSP once we added ReplayGain support.

So for now, you will have to look for a third-party VST plugin do this.

If there was enough popular support for the idea, we could add back a "dynamic" mode to the Volume Levelling DSP.

Alex,

Thank you for the link.  The link takes me to the kvraudio.com page for the Classic Compressor download.  When I clicked on the download link, it takes me to kjaerhusaudio.com without any file being downloaded.  

Do you have a direct link to the download that works?

Found and downloaded it from the softpedia.com site. :)

Thanks,

Does it support movies/8 channels or only 2 channel music? Seems the developer's web site doesn't exist anymore, do you know where to find any info on how to use it?

I'm very interested in the opposite of what the thread starter wants. I would love to have dynamic Expansion. This could restore the life to a lot of overly compressed music. Any others here that would like that too? (Please)

Any of those good for limiting dynamic range in movies similar to the Dolby range limiter built into most receivers? I run 8 channel PCM to my receiver and its built in limiters don't support that.

This is practically impossible. A dynamic range extender can only increase the difference between the quieter and louder parts of the track when they occur separately during the track. There is no way the revert the compression that has been applied to the content at a specific moment.

You can use the "Volume > Normalize" settings that are available in the fddshow audio decoder. Its "Regain volume" option works fine as a "night mode".

Thanks, I'll play around with that and see how it works :)

There have been several Expanders built over the years. One of the most popular was by DBX who made a few different models. Doing a Google will bring up lots of info on Expansion. People seem to love em or hate em. The consensus seems that their use must be judicious.

There is no question that many CD's are very compressed, especially Pop music. They do it to make the music loud! Records were compressed. FM is compressed. Applying expansion is basically the reverse process. Only problem is on the playback end we don't know what the compression settings were so it's impossible to do a perfect reproduction. Dolby produced some discs that had the settings encoded - I would really like to hear these.

The bottom line for me is that any alteration of the original is distortion. Therefore compression is distortion! If we can minimize that without producing other bad affects we are closer to the original.

Thanks, been playing with this. There isn't much in the way of directions, however.
I found this to be helpful.
