Find the uda1341 driver on the internet, compile it into the uda1341.ko module, and open the Kernel configuration menu.Device Drivers --->Sound --->Make modules generates the soundcore. Ko module. Load the two modules to play the audio. After carefully reading the uda1341 driver, we found that only 16 bits of audio can be played.Convert to dual-channel when copying to the driver. Therefore, we recommend tha

This design idea: first open a normal WAV audio file, from the 44 bytes in front of the defined file header, remove the file header definition message, placed in a file header structure. Then open the ALSA audio driver, from the file header structure to remove the sampling accuracy, the number of channels, sampling frequency three important parameters, using the

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

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

WAV is a lossless sound file under Windows, the file holds the audio PCM information and the player plays that music when most information is made, he has two blocks, the first block is the format block, the second block is the data blockFirst, the format block, the format block with a picture can be explained, as followsUsing Winhex to analyze a WAV
