What is a spectrogram? Spectrogram vs. Here is the same audio file using a spectrogram. How to fine-tune the display Not all spectrograms are created equal.
Using the spectrogram to solve audio problems There are a number of different audio problems that the tools in RX can help you fix. Hum Buzz Hiss and other broadband noise Clicks, pops, and other short impulse noises Clipping or distortion Intermittent noises Gaps and drop outs. Hum Hum is usually the result of electrical noise somewhere in the recorded signal chain.
Buzz In some cases, electrical noise will extend up to higher frequencies and manifest itself as a buzz. Hiss and other broadband noise Unlike hum and buzz, broadband noise is not concentrated at specific frequencies and can be found throughout the frequency spectrum.
Use the Spectral De-noise tool to remove these types of broadband noise. Clicks, pops, and other short impulse noises Clicks and pops are common on recordings made from vinyl, shellac, and other grooved media. Clipping or distortion Digital clipping is an all-too-common problem in audio production.
Zoom in on a waveform to see where the wave has been truncated because of clipping. Intermittent noises Intermittent noises are different from hiss and hum—they may appear infrequently and be inconsistent in pitch or duration.
These noises can manifest themselves in various ways. Here are a couple examples:. Gaps and dropouts Sometimes a recording may have short sections of missing or corrupted audio.

To view the spectral signatures of fluorochromes in a spectral flow cytometer, please visit the Aurora Spectra Analyzer.
The graph legend appears above the display, indicating the displayed spectrum. Excitation spectra are displayed as dotted lines, while emission spectra are displayed as smooth lines. Select Laser Lines To visualize laser lines select your desired line from the listed options 3.
Create Filters If you wish to visualize the degree of fluorescence transmission through your filter sets, enter the filter wavelength and bandpass into column 4. Turn your filters on and off using the checkboxes. Pinpoint spectral data To view exact data points on any graph, make sure the "Enable tooltip" box is selected and then mouse over spectra curves until a popup appears. For iPhone and iPad users, simply press on the location of the curve to view the same data display.
You can also pinpoint your mouse position using the Mouse Position indicator below the selection area.BioLegend's Fluorescence Spectra Analyzer is useful for the analysis of excitation and emission spectra of commonly used fluorochromes for flow cytometry.
