To get the maximum hold plot data and the frequency vector, you can use the object function getSpectrumData and plot the maximum hold trace only. data = getSpectrumData(scope); freqVector = data.FrequencyVector{1}; freqResponse = data.MaxHoldTrace{1}; semilogx(freqVector,freqResponse); xlabel( 'Frequency (Hz)' ); ylabel( 'Power (dBm)' ); title( …

Frequency Response Plotter 1.12a
http://www.pensa.fr/freqresplot/indexe.htm
Start the Frequency Response Plotter, you'll see this window: Select the Start and Stop frequencies from 10Hz to 24kHz (default is 20Hz-20kHz), and click on 'Start'. The program will proceed to a quick white noise calibration, if it fails, raise the volume or the record level and check your connections.
Mic Data 2: Frequency Response And Sound — AudioTechnology
https://www.audiotechnology.com/tutorials/mic-data-2-frequency-response-and-sound
A frequency response diagram will give you much more information, because it illustrates the microphone’s sound balance. For instance, if you see a rise in the upper frequencies of, say, 6 dB, you can expect the respective microphone to sound quite bright. However, a frequency response plot won’t tell you if you are going to like the character or “texture” of this …
7 Best Free Audio Spectrum Analyzer Software For …
https://listoffreeware.com/free-audio-spectrum-analyzer-software-windows/
Visual Analyzer is a free audio spectrum analyzer software for Windows. This software lets you analyze real-time phase spectrum of audio signals given through input audio devices. To do so, it provides multiple options to adjust step size (in dB), specify value considered as 0 dB, frequency range, distortion, etc.
Read audio wav file and plot audio freq response …
https://stackoverflow.com/questions/35663232/read-audio-wav-file-and-plot-audio-freq-response-smoothed-in-python
[x,fs] = audioread('file.wav'); ;; downsample 4:1 x = resample(x, 4, 1); ;; snip 8192 samples 3 seconds in x = x(48000*3:48000*3+8192); plot(abs(fft(x)); I'll leave it to you to get the plot formatted the way you desire but just a hint is that you'll need to construct a frequency axis and snip the desired bins out of the fft.
Filter frequency response grapher | EarLevel Engineering
https://www.earlevel.com/main/2016/12/08/filter-frequency-response-grapher/
Here’s a tool that plots frequency response from filter coefficients. The coefficients fields are tolerant of input format. Most characters that don’t look like numbers are treated as separators. So, you can enter coefficients separated by spaces or commas, or on different lines, separated by returns. That makes it easier to copy and paste ...
Understanding Frequency Response - Why it Matters
https://www.alesis.com/kb/article/2227
The concepts of frequency response, frequency range, audible frequencies, how frequency relates to musical notes, etc. are absolutely central—critical—to understanding how audio equipment makes, reproduces or records sound and how that sound is related to the live sound produced by singers and instrumentalists.
plot frequency response feature | DSP Concepts
https://dspconcepts.com/forums/audio-weaver-designer/478-plot-frequency-response-feature
Hi, I wanted to ask the following questions 1) I am using the plot frequency response on a target and it is very helpful. For the Biquad Cascade HP module, I can plot the response even while the target is running. The issue I run into is that when I have 20 biquads cascaded it plots properly but when I increase to 30 all of the sudden the plot freq response …

They only show frequency response into 4ohm load. Neither 8ohm load response, nor complex dummy load response. They probably know why they show only 4ohm plot. Now look at the THD+N vs power plot into 8 ohm. It is good up to 50W but then there is a sharp knee and at 70W they have suddenly 1% distortion.
