Wav fft freeware

To do so, it provides multiple options to adjust step size in dB , specify value considered as 0 dB, frequency range, distortion, etc.

After setting up all these configuration options, you can save configuration settings, or use Save as option to store these settings as INI files. Apart from audio spectrum analysis , it lets you apply separate filters various FIR and IIR filters to individual audio channels, analyze audio using Frequency meter, period meter, and voltmeter, etc.

It also lets you calibrate left and right audio channels using built-in measure signals. It lets you analyze the performance of sound card of your PC. You need to specify input and output devices to analyze them prior to initiating analysis process. There are four analysis options available in this software, which are Generator, Oscilloscope, Spectrum Analyzer, and Frequency Response. Spectrum analyzer lets you analyze db vs Hz plot of input audio signal spectrum in real-time.

All you need to do is, enter the number of sample in the specified field and click on Start button. Now, you can graphically analyze audio spectrum in real time. The Generator lets you generate sine, rectangular, triangular, etc. You can perform left and right channel analysis individually or simultaneously. The Oscilloscope helps to analyze audio input devices with adjustable horizontal scaling, resolution, offset, triggering mode , etc.

Frequency Response lets you analyze the frequency response plot of audio signals. All in all, it is an ultimate software for audio analysis that lets you perform spectrum analysis, frequency response analysis, and oscilloscopic analysis for audio signals. Friture is another good audio spectrum analyzer software for Windows. It lets you plot multiple graphs in order to perform audio spectrum analysis.

Also, you can change frequency scaling mode to linear or logarithmic mode. In Octave Spectrum analysis, you get options to change settings like Bands per octave, min and max amplitude in dB , response time, etc. For 2D spectrogram analysis, you can set time range in sec. Additionally, it also provides oscilloscope view of signals and generates sine, sweep, burst, pink noise, etc. One of the distinguishing features of this audio analysis software is that it supports multi-dock view i.

Frequency Analyzer is another free audio spectrum analyzer software for Windows. It is a simple and easy to use software with minimal options available at its interface. Visual Analyser is a complete professional real time software, transform your PC in a full set of measurement instruments.

No new hardware necessary you can use the Sound Card of your PC, or you can use a specific external hardware for example Plug. Visual Analyser version now available 32 bit platform , no longer compatible with Windows 9x. VA is a real time program which simulates a set of electronic instruments, such as:. Oscilloscope dual channel, xy, time division, trigger.

Samples an audio stream in bit stereo, then uses a Fast Fourier Transform to yield the spectral analysis in real time. Bargraph peak-level indicator shows time-domain peak levels and onset of clipping distortion spectrum also goes red. Stereo input, dual bargraph, choice of Left, Right, sum or difference for frequency analysis User selection of sampling-rates, including 32kHz, Spectrum obtained using FFT with Hanning raised-cosine window-function.

User-selection of different FFT transform sizes to trade-off time response and spectral resolution. New in v3. Now optional for all visualisations.

Vertical scale calibrated as fraction of digital full scale 'FS' with currently-set mixer-settings etc.
