View Full Version : Software Equalizer for Squeezebox?

To repeat a question I just E-Mailed, is it possible to create a plugin for Squeezebox that will provide multi-band equalization (i.e. like the equalizer in iTunes)?

would sox be able to do it?

Or something like Ozone Free, the analogue modeling software by izotope (http://www.izotope.com/).

This was the best plugin/upgrade to winamp in terms of sound improvement by far, and creates a nice warm analogue tube sound. Is it possible to use this in any way for SB?

Well, I'm about to pull my hair out. Sox has a "multi-band compander". I've searched for several hours, and I can't find a single example ANYWHERE that describes how to use the thing. I'm not even sure if a "multi-band compander" will give me what I want.

If you want an equalizer, you do not want a compresser or expander.
Without details, I'm guessing that "compander" can be set to either
compression or expansion, maybe both at differing frequencies.
They are dymanic gain controls.

You want frequency adjustments.

Really? I thought for a particular equalization setting in a multi-band equalizer you applied a certain number of decibels of gain for a narrow band of frequencies. Am I completely wrong?

Also, I tried the demo version of Izotope Ozone. There's no executable. Nothing seems to work except for the online help, which doesn't explain how to get anything else to work.

I tried demo versions of two other programs. One of them seems to do nothing but generate hissing noises. The other refused to install a demo version of itself because no "bill of sale" existed. I'm quitting for the evening.

Vote for bugzilla enhancement #2133 which requests 13 band firmware equalization added to slimserver/sb2.

I requested this of Slim about a month ago

As long as we can turn it off, fine.

I doubt it, if an equalizer is what you want. A multi-band compander
would be a compressor/expander, kind of like the dbx boxes of yore (or
perhaps still of today?). They're for increasing (if you have some sort
of compressed source and want to "open up" its dynamics) or decreasing
(if you want to track steadily nearer to maximum loudness, for example)
the dynamic range of the signal. They began being implemented with
multiple (most notably three, in the dbx 3BX) frequency bands in an
effort to avoid audible "noise pumping". (The latter would be audible
if, say, a big bass pulse caused the signal to be amplified, and the
original had some steady high-frequency hiss -- the hiss's volume would
be modulated by the bass expansion if they weren't sequestered in
separate bands.)

Thanks. I just voted for both 2133 and 729.

That's true. The goal is really to manipulate the volume per-band rather than try to expand the dynamic range.

I've also voted for these options, i would really like an equaliser on the Squeezebox, on the toslink and analog.

Any news on the bass & treble front? ;)

I'd like to see both some form of dynamics plug-in and an Eq/tone controls.

The dynamics module would be especially great for dinner parties etcwhen you need background music of limited dynamic range. The quiet bits don't drop away completely and the loud bits don't kill conversation.

Eq would allow those of us with minimal systems (just Squeezebox into active monitors) to apply a little tonal compensation here and there.
