This program can no longer be downloaded. Take a look at Boom 2 instead.
If you've ever had low sound problems on your Mac, then Boom is an excellent tool for increasing the volume on your Mac.
Boom is suitable for anyone that's had problems with low sound on applications such as Skype, iTunes and VLC media player. Boom can also be used for boosting the volume on online music and video sites such as YouTube, Vimeo, - Netflix, Hulu and more. Boom works by adding a graphic equalizer to your Mac's sound system so that you tweak and boost it.
Boom has been continually improved and fixed since launch although some users may experience a popping or clicking sound when it's cranked up to full volume. However, this should have been ironed out in the latest version.
If you're Mac speakers aren't loud enough, Boom gives them the boost they need.
