wav audio files

Recent work needs, to the WAV file stored in the Audio information analysis processing. So it took some time to collect the methods of processing WAV files in various mathematical softwares. Matlab Matlab is the most convenient. Even without writing any code can read WAV fi

play the Startup sound:Playsound ("systemstart", null, snd_alias | snd_async );The function sndplaysound is similar to playsound, but one parameter is missing. Function declaration:Bool sndplaysound (lpcstr lpszsound, uint fusound );Except that the resource name cannot be specified, the parameter lpszsound and playsound are the same. The fusound parameter indicates how to play a sound. It can be a combination of snd_async, snd_loop, snd_memory, snd_nodefault, snd_nostop, and snd_sync. These mar

PCM (pulse codemodulation----Pulse Code modulated recording). The so-called PCM recording is the sound and other analog signals into the symbolic pulse column, and then recorded. PCM signal is a digital signal composed of [1], [0] and other symbols, without any coding and compression processing. Compared with analog signal, it is not susceptible to the clutter and distortion of the transmission system. The dynamic range is wide and the effect of sound quality can be very good.
