New GStreamer equalizer range: -24..+12 instead of -1..+1

[Johannes Sasongko]

The GStreamer equalizer element changed the gain properties from -1..+1
(no specified unit) to -24..+12 dB. As the equalizer is now in
gst-plugins-good, it's not likely to change anymore.

I have no idea how the conversion works, but the old source seems to
indicate that the -1..+1 was equivalent to -12..+6 dB. If anyone knows
how to convert from the old to new values, please enlighten me.

I've just emailed the gstreamer mailing list regarding this. I see a few problems, though. In our current equalizer.ini file, there are values such as -5.5511e-17, which shouldn't work. Only in the negative range, though. However, in the glade file, all the slider max an min values are 1 and -1.

I found the winamp equalizer presets file, and I can't really tell if it's also using a -24,12 range.

The biggest problem I see is detecting what version of gstreamer is being used and adjusting accordingly. Is the answer to use two different equalizer dialogs, and two different eqlualizer.ini files (for default values)? Such as Equalizer and Equalizer2? All the widget names could be the same, they would just have different ranges on the sliders.

To be honest I don't know. If it was up to me I'd be lazy and simply
change the dialog and defaults to the new range, destroying users'
custom presets on the way, also breaking support for earlier versions of
the eq plugin. Not very nice but yeah... that would save us from some
code pollution.

The Equalizer works again... Thanks ! :)

A little difficult to adjust, just small adjustments otherwise distorted sound.

PS Equalizer is wrong spelled within Menu and Windows List :)

[Adam Olsen (arolsen)]

Where is the spelling mistake? I can't see it.

Sorry, I missed your question.

I have 2 locales installed, swedish and english.
English is set to default. Running Hardy, up-to-date

I also tried a clean trunk install with the same spelling... :)

This is not a big deal if I am alone with this error... ;)

[Johannes Sasongko (sjohannes)]

All "equalizer" texts are localised as "equaliser" in the en_GB locale (which is correct AFAIK); I'm quite sure that's what you're seeing in this case.

[Johannes Sasongko (sjohannes)]

Er, I meant, almost all of them are localised that way. I think the translator missed the "Enable Equalizer" text.

[Stefan Soriga (sgstefan)]

I see "fix released", but I still have this problem, although i run with hardy-proposed. Can somebody be more explicit? Thanks.
