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.

What is a WAV file.The WAV file directly reflects the size of a sound at each time point, for example, the following waveform:Take one point for 0.1 seconds each person. The obtained WAV file value is 0, 1,-, 1. Therefore, if we can directly add the data of many wav files, you will hear all the sounds, which is the pri

Wav TO amr and easy adjustment of the volume, wavamr volume Let's talk about how to convert wav to amr. Wav is the easiest way to generate recording audio on PC, but the disadvantage is that the generated audio volume is relatively large. Amr is a mainstream audio playing format on mobile phones. Its advantage is that the audio is small in size and easy to transm

I bought some CD last year and copied it with EAC on the PC and compress it into an ape. After the CD is sent, the missing CD is lost. Later, I switched from PC to Mac. Because iTunes does not support ape, I converted it into ALAC. Apart from a small number of ape s, they survived because they were misplaced, and all the other ape s were cleared. I recently added Vivo to try those songs in the natural environment. Unfortunately, Vivo won't be able to play those ALAC. What makes people laugh most

The playsound function is used to play wav files in VC.1. Function details:The playsound function is declared as follows:Bool playsound (lpcstr pszsound, hmodule hmod, DWORD fdwsound );The parameter pszsound is a string that specifies the sound to be played. This parameter can be the name of the wave file, the name of the wav resource, the pointer to the sound data in the memory, or win in the system regist

The first three articles have explained in detail how to convert the WAV audio format to the FLV format. This article describes how to convert the last part, first, the AMR is converted into WAV format, and then the WAV format is encapsulated FLV format.

Because you only need to execute it on Windows, first think about using the MCI interface. After a try, mcisendcommand can be used to play the basic WAV file. However, loop playback of Wav is troublesome. The message mm_mcinotify must be sent to the window. After Google, we found that there was a simpler method-UseSndplaysound. One statement, sndplaysound (filename, snd_async | snd_loop), can play audio f

Program Wednesday, September 2003 1:24 PM when a certain event is completed, the program sends a specific signal to increase the user interface characteristics of the program, such as when the download is complete or a command is selected.
