Description: 你是否曾经想知道，为什么不同的乐器上演奏同样的音乐，听起来确不一样呢？你是否想知道声音是如何可视的？欢迎入门波形浏览器!
随着这个小的应用程序，你可以通过添加许多频率合成声音。你可以听你自己的声音，并添加正弦波，知道它们听上去那么悦耳。
本例中的声音输出采用来自的A full-duplex audio player in C# using the waveIn/waveOut APIs代码。-Have you ever wondered why the different musical instruments playing the same music, do not sound the same? Do you want to know is how visual voice? Welcoming the entry waveform browser! With this small application, you can add the voice of many frequency synthesizer. You can listen to your own voice, and add the sine wave, know that they sounded so sweet. This case the use of the sound output from A full-duplex audio player in C# Using the waveIn/waveOut APIs code. Platform: |

Description: 本设计综合应用Windows低级音频API、G.729A编码算法、SOCKET编程、多线程编程等技术实现了在局域网PC机点对点的窄带全双工语音通信系统。界面通过MFC实现。为了确保发送应用层协议和聊天信息的正确性，采用TCP方式发送交互信息。语音模块的启动与关闭由交互的命令控制。考虑到语音数据需要延时小，这里用UDP方式发送。-The comprehensive application of the design of Windows low-level audio API of G.729A encoding algorithm, SOCKET programming, multi-threaded programming technology to achieve a PC in the LAN point-to-point narrow-band full-duplex voice communication system. Interface through the MFC. In order to ensure the correctness of the information of sending application layer protocol and chat, using the TCP send interactive information. The voice module startup and shutdown command and control by the interaction. Taking into account the voice and data delay, here sent using UDP. Platform: |

Description: Simulink® and Stateflow® model of a full duplex Bluetooth communication link transmitting HV1, HV2, HV3, and SCORT [1] voice packets, and DM1 data packets. A system parameters block configures the whole model s packet type, slot pair and channel type. Stateflow is used to implement the acknowledgement scheme for the data packets and the SCORT receiver state machine.
NOTE: A version of this model which works with the current release of MATLAB and Simulink is shipped with the Communications Blockset™ .
The model includes wave file I/O, CVSD speech coding, HEC, payload CRC for DM1, FEC, framing, GFSK Modulation, frequency hopping, hop sequence generation, an 802.11b interferer, BER meters, throughput meters, plus spectrum, timing and spectrogram plot (which can be turned-off).-Simulink® and Stateflow® model of a full duplex Bluetooth communication link transmitting HV1, HV2, HV3, and SCORT [1] voice packets, and DM1 data packets.
