ultrasound microphone

complicated from simple. In order not to make the application too complex, I chose a minimal set of functions that can implement my main goal. Because of its simplicity, it also avoids introducing potential bugs in many places, the following is a collection of reduced functions: Save recordings in WAV format Sort recordings by date or name Recording during screen lock Add remarks for recordings Using the xNa class in Silverlight applications, you can create two types of appl

Zheng Yi 20091119 Dongye often adds all kinds of knowledge points to his reasoning novels, so that you can enjoy his strict logical reasoning and get popular science. Two examples have been given above, such as the P/NP problem in "the dedication of the Suspect X", and the Monroe Effect in the predicate of the series "probe Galileo. Therefore, it is strongly recommended that science and technology students read the reasoning novels of dongqiawu and click here to package and download his 21 nov

(reprint) Common Audio Protocol IntroductionIntroduction and comparison of common audio protocols for conference TV white PaperFirst, the digital audio principle: The sound is actually a kind of energy wave, therefore also has the frequency and the amplitude characteristic, the frequency corresponds to the time axis, the amplitude corresponds to the level axis. Usually the ear can be heard in the frequency of 20Hz to 20KHz of sound waves known as audible, less than 20Hz to become infrasound, hig

The computer I saw in Company Q is basically Dell. The difference is that the chassis is closed and the drive is split. There is a steel bezel behind the chassis. All USB, serial port, parallel port, and PS/2 ports are locked inside, And the keyboard and mouse cannot be pulled out. All employees access the Internet through the HTTP proxy, and the export data is completely monitored. As long as the upstream traffic of a machine is slightly larger or the data is abnormal, someone will immediately

The first step, the mouse click on the lower right corner of the computer "small horn" icon, the right mouse button to choose "Recording equipment" this. [As pictured] In the second step, if you want to test your microphone, speak with your microphone. View the gray volume bar next to the device name on the Recording tab, as shown in the figure: Microphone

Technical operational issues Most friends now use headphones with microphones, this kind of earphone generally has 2 inserts the mouth, one receives the audio interface, another receives the microphone interface, if realizes the microphone interface to be possible, must speak the microphone the plug to connect the computer corresponding audio port to realize the

The Kinect microphone array is below the Kinect device. This column consists of 4 independent microphones horizontally distributed below the Kinect. Although each microphone captures the same audio signal, the array can detect the source direction of the sound. So that it can be used to identify the sound coming from a particular direction. The audio data stream captured by the

YY Voice Listen to other people say there is an echo how to do? First, please set your own sound card, Second note: Because many people or 2 people speak at the same time, because the network transmission is different, so it will cause echo phenomenon Ask your channel's administrator to right-click on the channel--set everyone to press the key to speak, one to say will not cause an echo phenomenon Finally, please turn on your small horn and set your

ASP. NET reflection, Two examples in reality:1. B-ultrasound: You probably have performed B-ultrasound during the health check. B-ultrasound can detect the physiological status of your internal organs through your belly. How is this done? B-ultrasound is a B-type ultrasound.

(Reprinted to dodo-yufan in the blog Park) Two examples in reality:1. B-ultrasound: You probably have performed B-ultrasound during the health check. B-ultrasound can detect the physiological status of your internal organs through your belly. How is this done? B-ultrasound is a B-type

Ultrasonic Ultrasonic (Waves): The frequency at which human ears can hear is 20hz~20khz. When the vibration frequency of sound waves is greater than 20KHz or less than 20Hz, we can not hear. Therefore, we refer to sound waves that are above 20000 Hz as "ultrasound". Because of its good directivity, penetrating ability, easy to obtain a more concentrated sound energy, in the water spread far away, can be used for ranging, speed, cleaning, welding, grav

someone sends a message asking "Where are you", Hangouts will automatically pop up a bubble and let people share the location directly to each other.EMU will also affect other Google products, such as Inbox, can also be directly based on the content of the mail, automatically provide geolocation, OpenTable, Yelp and other services. Copresence, cross-platform ultrasound pairing Google is developing an

The achievable accuracy for systems and multiple ADCs depends directly on the reference voltages applied to the ADCs. Medical-ultrasound-imaging systems, for example, commonly include a large number of ADCs in the system ' s Beam-former elect Ronics, with the ADCs usually organized in groups of--- To obtain maximum beam accuracy, you must minimize errors in the ADC path. Poor accuracy of the reference voltages of the individual ADCs degrades the overa

IOS recording and playing: A few amazing demands In a recent project, you need to connect the iPhone with a microphone (Apple is called Headset, and without a microphone is called Headphone), and then synchronize the recording and play. After this function is implemented, you need to change the Input Source for recording and playing. For Synchronous Recording and playback, you must use the underlying interf

1. See if the sound card driver is working properly under WINDOW7 system If the sound card driver exception recommends updating the sound card driver when testing the microphone is working properly. If the microphone is still unable to voice the next step. 2. See if the microphone speakers are working properly under the WINDOW7 system Click on the

A lot of computer beginners friends are very like QQ chat or video or something, one of them will encounter such or such a problem, one of which is that the QQ video does not sound the most happened, many friends feedback QQ video When you can hear each other's voice, but the other side could not hear their own voice, but their computer listening to music, Play video Everything is OK, what's going on here. QQ Video No sound we first have to think about a problem, how can the other party hear ou
