The max volume on my iMac is way too low. I can barely hear videos in some online videos for example.

I know the volume can go louder though — depending on the audio source the iMac can be very loud.

So how can I increase the sound volume?

What app do you use for these videos? – Mark Sep 10 '11 at 19:52
flash and iTunes are the other main problems. – ztatic Sep 10 '11 at 21:13
I'd like to be able to boost the volume for any app though. – ztatic Sep 10 '11 at 21:13
vlc included... – ztatic Sep 10 '11 at 21:14
Each od these apps has a volume control - have you got those at the max? – Mark Sep 10 '11 at 21:16

Mac App Store - Boom ($8.99):

You could modify the instructions at osx - OS X: Filter system audio-out to remove high-pitched noise? - Super User. That's too complicated to be used as a permanent solution though.

iTunes has an option to normalize the playback volume: Preferences → Playback → Sound Check. As does VLC: Preferences → Audio → Volume Normalizer.
