If a thread attempts to use the sharing resources, it first acquires the critical section object. Our system is an datqsheet Karoke system to help people sing better; 6. The multimedia system allows the users to select preferred sampling frequency for compare and contrast purpose. The Lower Pitch distortion option is done by averaging the past 16 voice signals from our test. The source code is the dqtasheet project created by the version of Visual Studio In the function processSignalthe following code is to get the voice signal from ADC, store the signal to a sample buffer and then start another conversion.
This system allows users to use the microphone as the analog input to speak and sing. The dataflow between da0c801 microcontroller, the console program and the Java application. Besides, we are able to synthesize the data and generate some amazing effects.

We chose this topic because we are all dac0810 in multimedia signal processing. Our program configures the serial port to run at a baud rate of bps. If we use it for both voice and music signals alternatively, the sample rate will be reduced to less than half of the original one.
Besides, we use the RS serial port to communicate between the microcontroller and the PC. At the same time, the user can change the setting and effects of the multimedia system without noticing the delay in command process.
Figure 5 shows the circuit of the pre-amplifier of the microphone voice input. A state machine is implemented in the packet reception. The default argument is set to COM6. In the point of view of the multimedia industry, the application of audio processing is very important.
The console program configures the COM Port to run at a baud rate of Do not exceed negative logic input range of DAC. The Walki-Talki distortion option is done by distorting the voice signals to its square from the result of our tests.

Moreover, the thread stores the data into an array buffer until one second is elapsed. The packet structure for command packet has 4 bytes. Every time, the program reads an input from the pipe.
The checkCommand function handles the command packet sent from the PC software. Therefore we implemented a datasheeet buffer of size bytes to store the signal samples and reuse the buffer continuously.

Pin 4 of PortD is used to control the WR pin dxc0801 ADC in order to command it to start another conversion by setting it to be 0 and then 1 immediately. The first 2 bytes are for 16 bits command. The stop bit is one. Pin 1 and 2 of ADC are the and control pins which are connected to ground to enable the chip all the time. If he wants to reset the MCU without dataseet the PC software, he should make sure that the multimedia system has been turned off before.

Those algorithms that we found are well suitable for our sound effects. The program gets the command from the graphical user interface and transmits it to the microcontroller, and at the same time receives the real time digital audio data from the microcontroller.
This is because the DC-offset is not exactly 2. In our system, there are totally 5 distortion options that a user can choose from. All the configurations have been setup, but you need to install Platform SDK as mentioned before.
