Is possible to amplify the system sound with software, without losing sound quality?I want it for videos and,especially,for listening to music. What programs for Ubuntu 12.04 can do this?

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.

  • For what use case do you need this? Many audio tools ship their own set of amplifiers so if you want to listen to music / watch video the answers will be very different to if you want to play games and have your teamspeak amplified. Please do provide more detail on what you do and how you would want to change it. – Angelo Fuchs Mar 14 '14 at 19:42

  • Please edit your question to state all of your requirements. You already tried Pulseaudio volume control and found it unsatisfactory — so you need to mention that in your question, and explain why it isn't suitable! By not doing this, you're wasting our time finding suggestions that don't help you. – Gilles 'SO- stop being evil' Mar 14 '14 at 21:06

You can use the sound server PulseAudio Volume Control (aka. pavucontrol and previously known as Polypaudio):

  • free
  • run on Ubuntu (KDE/Gnome)
  • amplify the sound (default max boost: ~150%)
  • however the higher the amplification, the more distorted the sound will be

FYI if you want to go over the default max boost (~150%): see this thread.

  • I already tried it,but I want the best quality ever! – VIPaul Mar 14 '14 at 19:58

    Can you please add in your question which applications you tried, and what's the best you've found so far? – Franck Dernoncourt Mar 14 '14 at 20:10
