An FR measurement compares the output levels of an audio device to known input levels. A basic FR measurement consists of two or three test tones: mid, high, and low. In this example you perform an audible range FR measurement by sweeping a sine wave from the lowest frequency in the range to the highest. A flat response indicates an audio ...

make other measurements. If you want to measure the frequency response, or impulse response, of a listening room for example, that measurement will be affected by the quality of the audio interface that you are using to make the measurement. Therefore, it is important to know how your measurements will be influenced by your audio interface.

Speaker and measurement microphone positions. Positioning the Microphone It’s time now to set up the measurement microphone. The mic used here is part of Audio Precision’s MMK2 kit. It’s a pre-polarized, ½” microphone with a free-field response capsule. That’s a good choice for this application.
Instant Audio Frequency Response Measurements

Instant Audio Frequency Response Measurements using Soundcards, FFT-Software and Multi-Sine Signals. Frequency responses are usually measured by sweeping sine-signals as source and a display plotting the returning amplitude versus the frequency. This is quite a time-consuming method, and if low frequencies, high resolutions and/or high ...

If a speaker's frequency response measurement reveals a big peak of, say, +4 dB at 4 kHz, up in the mid-treble range, the speaker is going to sound bright and thin. If the response gradually declines above, say, 2 kHz to the point where it's down -6 dB at 20 kHz, the speaker is going to sound dull. This is a simplification, of course; read my ...
