Measure Frequency Response of an Audio Device The frequency response (FR) is an important tool for characterizing the fidelity of an audio device or component. This example requires an audio device capable of recording and playing audio and an appropriate audio driver.
Measuring the Frequency Response of Your Audio Device
https://www.faberacoustical.com/fileadmin/Downloads/MeasuringAudioDevices.pdf
focuses on using the Dual FFT Analyzer to measure the frequency response of the audio device that you use to 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.

"Audio Frequency Analyzer" is a powerful real-time audio analyzer (RTA) app for iPhone. This app can measure the frequency response in 30 split band scale of 1/3 octave in real time. Also it can be displayed the FFT analysis result.
How Many Ways Can We Measure Frequency Response? - Audio ...

APx500 software provides many ways to measure frequency response, or the ability of an audio device to reproduce audio signals over a frequency range of interest. If you had to qualify an audio device with a single measurement, that measurement would likely be frequency response.
Measuring Frequency Response: Single Mic or Multi-Mic ...

Below 200Hz, the five measurements are very similar. No matter where we move our head (or the microphone), we hear the same thing. Above 1kHz, the measurements vary a lot. Moving the mic changes the frequency response by 25dB or more. Not only do the measurements vary from position to position, they include a lot of very narrow peaks and dips.
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

BW = fcu – fcl Step-Response Measurement The lower and upper critical frequency values of an amplifier can find with the use of step response technique by giving voltage step to the input of amplifier circuitry and calculating the rise and fall time of resultant output voltage. The basic configuration is shown in the below figure.

All you need to do is, set speed (FFT’s per seconds), sampling frequency, points per transform, the source of input audio, etc. options and click on Start button. Now, you can visualize the audio spectrum. There are two separate application windows present on its interface to represent audio signal in wave and frequency spectrum view.
