What I am looking for is to have system wide implementation of sound enhancements like bass boosts, echoes, Fidelity, Stereo enhancement and so on.

Audio Video players have their own equalizer but they enhance only the audio / video files they are playing.

So to enhance sounds playing such as: YouTube, Spotify, System Sound, etc. I need a enhancer software. Back in Windows, I used to use SRS HD audio lab to do the same.

P.S. I have a horrible Speaker set.

pulseaudio equalizer is the way to go.

here's a blog post about it: http://www.webupd8.org/2011/04/system-wide-pulseaudio-equalizer.html

the relevant code:

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install pulseaudio-equalizer

This is what i wanted. Sadly i see they have discontinued it.I was hoping to see this expanded and integrated to ubuntu –  user15873 Oct 27 '11 at 7:10
    
@user15873 it may be no longer supported but it works really well all the way up to 11.10. Those 3 commands in terminal will get you a fully functioning, system wide equalizer. –  greg Oct 29 '11 at 21:53

Works fine in 12.04 –  Takkat Aug 6 '12 at 21:00
    
I did this and it had too many quarks with too little improvement to sound quality. Unfortunately, when I removed it via CLI I also did the recommended "autoremove". Now, after a restart, I have no sound menu indicator and don't know how to get it back. I would use this the pulse-audio eq with caution. –  jwdinkc Oct 31 '12 at 18:15
    
@Takkat Pulseaudio has support for built in equalizer, but it is not enabled in ubuntu (Why?). How do I enable it by recompiling pulseaudio from source (12.04 & 12.10)? –  Khurshid Alam Dec 30 '12 at 11:48

Psyke83's on the Ubuntu Forums wrote a 'script' to do this for PulseAudio.

Ubuntu 10.10:

Currently the easiest method is to install from a deb created by WebUp8.

Ubuntu 10.04 and below:

There is a PPA containing the equalizer:

sudo add-apt-repository ppa:psyke83/ppa
sudo apt-get update && sudo apt-get install pulseaudio-equalizer

Nope does not work for 13.10, but webupd8 solution accepted here works –  Benoit Jun 5 at 12:19

I was looking for a graphical eq package for Ubuntu 12.04 and found this post. Thanks a lot for this!

Unfortunately the link provided for WebUp8's deb is no longer valid, but there's this one that I found hosted on UbuntuUpdates.org and works perfectly.

I found that the easiest way of installing it is via the deb package. Installs right away w/o hassle. And this little thingy works, eh? Even stays permanently after a reboot! System-wide all the way**.

**Actually, I realized why: the eq application is just a frontend for adjusting the DSP's eq settings in PulseAudio; so mainly it's PulseAudio (ALSA?) retaining the settings - the eq interface is just there to allow accessibility to these settings. (I'm a total Ubuntu noob, hope this makes sense)

Too bad it's no longer supported, I wonder why not. But works on Precise alright.

Confirming that this one worked out of the box on Precise, while the accepated answer one 'failed to initialize the PA modules'. –  alexei Dec 27 '13 at 0:03

I've recently described it here: Global_equalizer_for_ALSA

Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference, thanks! –  jrg Feb 17 '12 at 1:07

You can install PulseAudio with system-wide equalizer support. This is basically an update to the old PulseAudio System-Wide Equalizer. There are more details in this blog post.
