(b) Tone and balance
How good an audio program sounds to you is largely
determined by the mix of the treble, mid
−range, and bass
levels. In fact, different kinds of music and vocal programs
usually sound better with different mixes of treble, mid− range,
and bass.
A good balance of the left and right stereo channels and of the
front and rear sound levels is also important.
Keep in mind that if you are listening to a stereo recording or
broadcast, changing the right/left balance will increase the
volume of one group of sounds while decreasing the volume
of another.
