Real time spectrogram software


















Note: Coagula converts image to sound file with Logarithmic Frequency Scaling, thus you will notice distortion in frequency direction unless you check the appropriate option in UltimaSound see the screen capture below, the left image is produced when Logarithmic Frequency Scaling was on, the right is when Logarithmic Frequency Scaling was off Sample BMP file that produces the sound image in the Youtube teaser video.

Sample audio file that produces the sound image above Based on your PC's performance, you may need to adjust the height and width of UltimaSound panel to achieve the best proportion for the image. Faster and smoother charting Three scaling options for the frequency axis: Standard Frequency Scaling, each pixel line represents one frequency component and you may use the horizontal scroll bar to scroll the interested frequency range into view.

Logarithmic Frequency Scaling, to fit the full frequency range to the charting area with a logarithmic scale. Narrowband spectrogram Narrowband spectrograms use fine-grained regions on the frequency axis. This has two main effects: firstly fine temporal detail is lost which means that the individual larynx pulses are no longer seen; secondly fine frequency structure is brought out consisting of the harmonics of the larynx vibration as filtered by the resonances of the vocal tract.

This kind of display is most useful for the study of slowly varying properties of the signal, such as fundamental frequency. The bandwidth for the narrowband display is fixed at 45Hz.

Hints and tips Use the Spacebar to toggle recording on and off. Use the left and right arrow keys to scroll the display left and right when paused. As well as monitoring an input microphone or line-level signal, you can monitor the computer's own audio output signal using options in the Windows mixer control.

The grid marks are Hz and ms apart. Want to learn more? Also, it facilitates you with a signal generator, oscilloscope, and spectrum analyzer. From the right side of the interface, you can set dB limit from dBu to 20 dBu , and frequency limit 10 Hz to 50KHz to provide sufficient dynamic range for signal fluctuation. Thus, lets you perform audio spectrum analysis in a better way. As you launch this software and click on Go button, it starts showing signal fluctuation in real time provided an input device e.

You can change signal frequency and amplitude range to alter microphone sensitivity; thus, specify a new range of signals to appear on the screen. Also, you can switch to Oscilloscope view mode. In Oscilloscope view mode, you get options to change values for time per division, volts per division, specify trigger source , etc. The generator helps to generate sine, square, triangular, impulse , etc.

In the free version of this audio spectrum analyzer , the Spectrum analyzer option provides only 1 octave real time analyzer mode. You can update to its other versions to get more options. Oscilloscope Winscope is an excellent real-time audio spectrum analyzer software for Windows. Using single trace mode, you can get only amplitude spectrum of real-time signal, while dual trace mode lets you analyze both amplitude and phase spectrum. There are several sliders available on its interface to adjust gain, sweep frequency, trigger level, position of plots , etc.

If you choose dual trace mode, then Pos Y1 slider controls position of amplitude spectrum, while Pos Y2 slider governs phase spectrum position of the input signal.

It provides an option named Save data to save the spectrum related data in DAT files. Home Page. Download Page. About Us. Estimated Processing Time Before Shipping: business days. Ref 1 User Licence 5 User License. Add to Cart. Continue Shopping or View Cart. Tweet Share Pin It Email.
