Where is the Twitter audio space open?

Twitter audio space is: make sure that after BeatsFitPro is upgraded to the latest firmware, open the settings icon of the phone. In the settings, click the Bluetooth option.

AirPods3 will automatically update the firmware after connecting to iOS 14. Then click the Bluetooth option of the mobile phone, and when you enter, a window of spatial audio will pop up when you wear it.

Click below to watch and listen to the effect. After clicking, select the option below to open when supporting video. Then, when the AirPods3 device is connected, press and hold the earphone device, and then click the space audio at the lower right to turn on this function.

Sampling frequency:

Because wav uses digital signals and uses a bunch of numbers to describe the original analog signals, it is necessary to analyze the original analog signals. We know that all sounds have their waveforms, and digital signals "take points" on the original analog signal waveform every once in a while and give each point a numerical value.

This is "sampling", and then connect all the "points" to describe the analog signal. Obviously, the more points taken in a certain period of time, the more accurate the waveform described. This scale is called "sampling frequency". Our most commonly used sampling frequency is 44. 1kHz, which means sampling 44 100 times per second.
