The format of the wave file in the wav file header: 00 h 4 char "riff" flag 04 H 4 long int file length 08 H 4 char "wave" flag 0ch 4 char "FMT" flag 10 H 4 transition byte (optional) 14 H 2 int format category (10 h is PCM sound data) 16 h, 2 int channels, 1 single channel, 2 dual channels 18 h 2 int sampling rate (nu

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 are also divided into several types, and the corresponding non-data information is stored in the file header section. Below are various WAV file header formats. Table 1 wave File Header Format for 8 KHz sampling and 16-bit quantization of linear PCM speech signal

value is the number of channels × the data bit value per sample/8. The playback software needs to process multiple bytes of data of this value at a time to adjust the value for the buffer zone. 22 h 2 　 The number of data digits of each sample, indicating the number of data digits of each sample in each channel. If multiple channels exist, the sample size is the same for each channel. 24 h 4 Char DATA tag "data" 28 h

Problem You want to have a method for playing sound quickly. Solution In xna3.0, you can directly load and play sounds from xNa without loading them using xact. Although this method removes some advanced xact functions, it makes playing sound very easy. Working Principle First, add a sound file to the project. The method is the same as adding an image to the project. For more information, see tutorial 3-1. The simplest solution is to drag a .

Write to WAV file Wav files are in the format of Resource Exchange files (riff), including a number of naming blocks, including header information (such as audio sampling format) or data (such as the sample itself ). Windows 32 API provides functions such as opening and disabling the javasf file and searching for

WAV files are resource Interchange file formats (RIFF), including a number of named blocks that contain header information, such as a sound sampling format, or data (such as the sample itself). The Win API provides functions such as turning off Fiff files, finding blocks, and so on. The names of these functions begin with "Mmio". The DirectSound API does not include methods for writing

How can I play a wav-file from memory or blob-field?Sometimes you needs to play a some sounds from own app but store these sounds in blob-field of table or in some external files. To play a wav-file you must call the playsound procedure which have the few parameters-sound (which you want to play ), handle of

1, import wave used to read and write WAV files It provides a convenient WAV format interface. However, compression/decompression is not supported and mono/stereo is supported. Read format: Open (file[, mode]) If file is a string, open it or treat it as a class file object.

project. Now we have a new empty project. In the tree directory on the left, find wave banks, which contains waves, which is the audio file. Right-click wave banks and select new wave bank. Then, right-click sound banks and select new sound bank to create a new sound bank. Sound bank contains sound, which are the objects actually played in the xNa project. A sound points to a wave, and some effects can be added to the wave. Now there should be two
