Off-Axis Frequency Response Charts

[philbagg]

I'm doing a report on four different microphones, and they're looking for
different specs etc. One of the mics has to be a multi-pattern condenser.

That's fine. The problem is they're looking for the frequency response charts,
on and off axis. I can't find any off-axis ones

Little help?

when the charts show the lobes like the figure 8 in the middle where they meet, just out side is the off axis, they don't tell you that they assume that you understand it. Same with all the other modes.

@Moresound... I think you've misunderstood philbagg's question. You're talking about polar pattern charts - he's looking for off-axis frequency response charts. Mics do not exhibit a constant frequency response... it varies with position of the source relative to the capsule (both angle and distance).

Here's your problem, you get one of two options: a frequency response chart that shows 0 and 180 degrees, and/or polar pattern charts that give you several different frequencies (e.g. 250, 1k, 2.5k, 5k, 10k).

A true complete polar/frequency response chart is a three-dimensional object, something like a waterfall chart would work, but I've never seen anybody do one.

The KSM44 has a good multiple-frequency polar response chart.
