Spotting the Trend: Real World Example
Let’s take a look at the following frequency response trace. In this
example we can see a few peaks that don’t go along with our
application, for our purposes, let’s make that a music concert.
Our goal is to get from this:
to this:
…all the while keeping in mind that we cannot alter the speaker’s
frequency-response curve, even if we would like to.
Looking at our trace, it’s easy to spot a few problem areas. There’s a
bump at 300 Hz that could be smoothed out a bit. Another bump
at 750 Hz could stand some flattening, and a big rise at 1 kHz to
10 kHz is going to make our system shrill at higher volumes.
What about all the other bumps and dips? Remember: The frequency-response
trace is not a video game. You don’t need to put a filter on every bump or dip
in your trace when a few carefully placed filters will achieve a much better
result. This is also why the wizard overlays the trace on your parametric EQ.
