![]() ![]() You can scroll up and down this spectrogram using the mouse wheel to see different parts of the frequency range. Here you can see a brighter band that shows the dominant pitch in the vocal track analysed rising towards the middle, then falling in steps. In a spectrogram the horizontal axis represents time, the vertical axis represents frequency, and the intensity of colour represents the amplitude. ![]() The attacker can edit the 802.11 header and spoof the MAC address of an access point. You can expand the display or make the track full height to magnify the spectrogram: A good example of a standalone spectrum analyzer is the Wi-Spy USB. In the picture below it is superimposed at 100%, so the audio underneath has been made invisible. ![]() The Analyser process can display a spectrogram that represents the spectral density of the audio signal over the duration of the process in question (governed by the process start and end times).Īdjust the Spectrogram Intensity control to affect the visibility of this, superimposed on the audio track in question. ![]() It will change as you move the play head, either while audio is playing, or while you scrub replay or move the play head position. The simple spectrum analysis display shown in the process control panel above shows the short-term frequency spectrum of the signal at the current play head position. ![]()
