Analogue Audio Source Analog audio is the technology of representing and processing sound through continuously changing signals. The advantage is mainly reflected in the ability to provide more natural sound output. Due to its continuity, analog audio can seamlessly capture subtle changes in sound, which makes it particularly popular in music production and high-end audio appreciation. There are two analog audio sources. When an audio player such as a mobile phone or computer is connected to the Line/MIC IN port via a serial port to a 3.5mm audio cable, select “Linear Input” as the audio source. When a headphone cable with a microphone is connected to the headphone icon port, select “Microphone” as the audio source. The analog audio delay can be adjusted by increasing the frame level delay to achieve audio and video synchronization.

Histogram
The histogram shows the distribution of image brightness, which can help users quickly understand the image exposure. The horizontal axis represents the brightness range, from left to right corresponding to the pixel values from the darkest (pure black) to the brightest (pure white), and the vertical axis represents the number of pixels at a certain brightness level. The histogram can determine whether the image is underexposed, overexposed, or properly exposed.
1. Shadow (dark part): corresponds to the part of the histogram that is biased to the left. If the curve is concentrated on the left, it means that the overall image is dark.
2. Midtone: corresponds to the middle part of the histogram. If the curve is concentrated in the middle, it means that the light and dark transition of the image is natural and the exposure is relatively normal.
3. Highlight (bright part): corresponds to the part of the histogram that is biased to the right. If the curve is concentrated on the right, it means that the overall image is bright.
There are two ways to open the histogram: one is to directly click the “Histogram” icon in the monitoring toolbar on the right side of the main screen; the other is to click the menu icon in the lower right corner of the main screen, select the “Monitor” option in the pop-up interface, and turn on the “Histogram” control switch in the “Waveform” option.
