4.0 to 4.1 Easiest Way to Add LFE channel to Quad (4.0) mix?

[ghalteman]

I have loads of 4.0 FLAC files with silent center and silent LFE channels. Some of the titles could use some bass boost. Without going into Adobe Audition and deriving an LFE channel from all four channels, is there a quick remixing program that will generate and replace the silent LFE with a functional LFE at a proper volume ? The Music Media Helper program I have can't do that.

Foobar2000 plugin?

I would just add the boost on playback. You could add bass boost to the main channels with Audition as well, easier than creating a separate lfe channel.

My old Yamaha AVRs have a bass management function to double the front content to the LFE.
Listen to a lot of stereo that way, currently Frank Zappa Petit Wazoo at Winterland 1972.

For quad that has bass in the rear channels, I rely on full-range speakers & tone control if necessary.

Your mileage may vary.

I wouldn't bother adding a channel to a file, just get some form of DSP and use a low-pass filter to create a .1

That will work, as will any crossover that will route it's bass to your subwoofer.
What AVR are you using?

The Music Media Helper program I have can't do that.

What version of MMH do you have? I've done this for a long time using the menu option here. Simple and quick.

He doesn't want a blank lfe channel. He wants one derived from the four main channels. Not really necessary IMHO.

Depends on speakers I suppose.
Sound Forge works good for EQ work.

I guess you don't have an AVR that does this automatically with speakers set to small and crossover set the right way?

Yes. Bass management does this! Creating a new LFE is silly.

(For those AVRs that 'need' an LFE to play quad, a silent one will do)
