Today I replied to a customer who was inquiring about SoundBunny for Mac OS X Mountain Lion . He had a incident where he was in a meeting using Skype on his Mac and was also connected through a direct connection with the meeting participants. He had a issue where there was feedback coming from Skype when talking in the meeting . He tried using headphones but he could not turn off one sound over the other. He wanted a application to control the volume level of Skype as well as the other open apps that were causing the feedback.  I explained that SoundBunny actually will control each application individually so you can mute one application while using the other to minimize feedback and invited him to try the free trial version of SoundBunny.
