We all know the modern complaint: movie sound sucks now unless you have a high-end sound system. Frantically turning down the volume after turning it up to hear the dialogue only to need to turn it up again can be frustrating. Now, this doesn’t solve the underlying problem, but why not have a “Volume A” and “Volume B” you can easily set and toggle between with the simple press of a button?
Many shows broadcast in surround sound. This includes a center channel where most voices are. Unfortunately if you don’t have a system to support this, audio is “down mixed” to stereo, and the center channel gets merged into left and right. When this merge happens, you lose definition between the streams.
It would be nice if you could boost the center channel, like you would in a home theater, but before the down mix occurs.
