The 3.DAC output voltage depends on the master I/O level, and the peak-to-peak value is up to plus or minus VDD. 4. Use Adobe Aduation software to test the frequency response characteristics, when tuning the sound, you need to determine the frequency of the master control. 5.

Two days ago, I found a wonderful thing in # jiushu's warehouse #. (In fact, many people have already said that jiushu's warehouse is a treasure chest .) It is called UMPC. Simply put, it is a computer with a small screen. The most amazing thing about a computer with a touch or Bluetooth or a wireless keyboard is fingerprint recognition. The price of such a wonderful thing is still very expensive. In fact, there are already many such solutions, such as super books. However, a few years ago, UMPC

solved. If the cables are not good, it is not safe to pull the cables. If you do the Redo, it will take time and money not to say, it may damage the overall decoration effect. Therefore, before the decoration, do not forget the wiring project of this system if you like music. 5. video sharing with redteeth Control Many of my friends think that watching movies is just in the living room.

the terminal: $ Sudo apt-get install bcm43xx-fwcutter The bcm43xx-fwcutter will automatically download and install the driver, then you can start the wireless network card in "networking", and HP3202AU wireless network card switch light will also become blue. This only enables wireless NICs. If you want to see the wireless connection status in the notification area, you still need to do some work. Installing Ubuntu on HP3202AU is the same as installing Ubuntu 6.10 On HP3240AU. The sound card

UbuntuPC manufacturer System76 has released a touch notebook equipped with Ubuntu13.10. DarterUltraThin14.1-inch high-definition notebook equipped with Ubuntu multi-point touch display, with a thickness of 0.9 inch and a weight of about 4.60 (about 2 kilograms ). Surprisingly, although affected by the Linux battery management defect, the battery actually supports 5 hours. In addition to touch screens, traditional input devices such as multi-point touchpad and chocolate keyboard are also provided

scope (this is my conjecture that due to limited equipment and equipment, there is no system test, interested friends can use the relevant testing equipment for testing), then, since there is bandwidth, good guy, we can achieve our communication channel through this band! It is also worth mentioning that the audio signal transmitted online on the headset is communication! Next, let's take a look at the pin definitions of the common in-ear monitoring plug-ins (Public headers) on the market. For

, but the power supply current is limited to ma. 14. The headset is incompatible with the sound card or motherboard. Sometimes, after you plug in the headset, you find that the sound of the headset is very small and cannot be used normally. There are two situations: (1) earphone Impedance The earphones we normally use are 8 ohm impedance headphones. If we purchase high-impedance headphones or other special-purpose headphones, we will feel a little sou

, this small in-ear monitoring port can also do a lot of things. The audio interface of the mobile phone can be used to remotely control hardware and send signal commands. The biggest obstacle to innovation is imagination. Mobile phone audio interfaces have unlimited application potential. Reporter: What is the operating mechanism of the android audio interface? Li Peng Jun: the operating mechanism is not mentioned. In fact, the audio interface is very familiar to everyone. Our first response is

places will inevitably leave some dust marks. In addition, check whether the body screws are brand new and whether there are any traces of screwdrivers being screwed. It should be noted that many new mobile phones have an obvious sandalwood smell, while old phones and shell-changing machines do not have such a smell, or the smell left by working hours.5.

I have previously written an audio-driven codec analysis. At that time, I ignored the most basic concepts. To understand something, you must first understand what it serves, and then better analyze its workflow. So here we mention:Codec: audio chip control, such as mute, turn on (off) ADC (DAC), set ADC (DAC) gain, and earphone mode detection.I2S: digital audio interface, used to transmit raw data of digital audio streams between the CPU and codec. Wh

. Like BBE, it is the most important sound effect many years ago and is widely used in TV, computer, audio and even earphone equipment. SRS has an overall high-frequency gain, which is the second optimal sound effect I have ever seen (the first sound effect is SONY's sound effect), and the high-frequency gain is very direct, the most outstanding SRS technologies are 3DSPEACE and 3DCENTER. srs wow is used on MP3, which combines the sound effects of SPE
