This paper mainly introduces the player to collect the sound and network transmission, the use of sound card A / D, D / A technology and the convenience of MATLAB programming and visualization capabilities, a voice signal digital processing program, and the other is DSP technology and the use of sound card LabVIEW multithreading technology, a sound card based on the data collection and analysis methods. Introduced, including WAVE, MIDI, MP3 audio files of three ways of player. In the transmission connection, I introduce the Winsock remote network-based transmission.
Finally, the introduction of Microsoft Visual C + +6.0 and the development process of visualization technology, as well as in Microsoft Visual C + +6.0 development environment for a procedure based on the API tape recorder so that it recorded a simple, playback and save it as a wav documents.
