The curve represents the average frequency distribution over the sample “Comfortably Numb”.

Spectrogram

Spectrogram is another representation of frequency versus time of a track. For each channel (right and left), horizontal axis represents time, and the vertical axis represents frequency. The amplitude is represented by the intensity (brightness) of the color of each point in the image.

The yellow arrow represents the normal collapse arround 22 kHz (sampling frequency at 44.1 kHz or 48kHz of the master). No signal above 22kHz (black lines).

Spectrum

The curve represents the average frequency distribution over the sample “Comfortably Numb”. The 6 curves represent the 5.1 signal (Right, Left, Center, LFE, Surround Right, Surrounf Left). The yellow area shows the limit in the low frequencies of the surround channels below 200 Hz. The White area shows the limit à 22 kHz for Right, Left, Center, Surround Right, Surrounf Left. The maximum frequency of the LFE ( Low Frequency Effect) it is lower around 100 Hz.

Spectrogram is another representation of frequency versus time of a track. For each channel (right and left), horizontal axis represents time, and the vertical axis represents frequency. The amplitude is represented by the intensity (brightness) of the color of each point in the image.

The yellow arrow represents the normal collapse arround 20 kHz (sampling frequency of the master at 48 kHz). Above 20 kHz , there is no signal (black area).

The green arrow represents the limit of the LFE channel arround 120 Hz.
