After the upgrade of the sound card suddenly can not use, find a lot of methods, and finally reinstall ALSA Drive solution. Back up for later use. You can refer to the compile alsa-utils here when there are errors, to install Xmlot, with the new profit search installation can be

1160 CD alsa/alsa-driver-1.0.23/
1161 ls
1162./configure--with-cards=hda-intel
1163 make
1164 sudo make
1165 sudo make install
I reinstalled my computer yesterday and found that the sound card could not be installed.Driver genieTested. The model isIntel 82801db ich4-ac'97 Audio Controller [A-1]
As a result, more than a dozen drivers of this model cannot be installed, and other software is used for testing.

It's been a long time today. Intel integrated graphics display. Finally it was all done, and here's a record.1. The first thing in the BIOS is to open Intel HD graphics. I set it up as the main video card, and the monitor is also connected to the port of the core graphics card. After restarting, I card warning low resolution, into the desktop 2. The command to sw
Because the regular Windows key +p key switches are often unable to switch to the external display, when you encounter the Windows key +p can not switch normal switching to the video card console debugging an external display attempt, if you cannot pull out the video card console for the graphics driver need to reinstall the video driver.

the power of this part of the frequency is relatively high. Similarly, when the high-pitched violin sound sounded, the frequency of the spectrum of the high-jump, indicating high-frequency part of the higher power. It is because of this relationship that the spectrum is always "a contrast" with the music being played.To display the bounce spectrum in the player, you need to know the power of each frequency in the
The general sound visualization makes the spectrum map on the line:But I don't think the spectrogram can see what the sound is, so be sure to make a sonogram, both of which get information about the frequency of the sound.This paper studies the two examples of Auriotouch and Pitchdetector on the official web, and integrates the main code obtained by Auriotouch's audio-visual display and pitch detector frequ

It is necessary to increase the time for taking a video or video during video chats, taking photos, and even recording videos. For example, video recording. When you want to know when a video is being viewed, time is the best proof.If you are using a brachat third-party audio/video solution, you need to use brachat r00005 later. You can add timestamps to local videos. timestamps are stacked in the upper-right corner by default, the

1. Add reference
2. initialize the multimedia Manager
3. implement various windows for displaying OMCS Functions
4. Add an unmanaged dynamic library
1. Provide support for WPF
The default dynamic library provided by OMCS can be used directly in the WinForm client program. If the client is developed using WPF, You need to reference another dynamic library: OMCS. WPF. dll. OMCS. WPF. dll is a WPF control library that overrides various connector components/controls in OMCS.
When using the js-sdk to collect audio, you want to display the spectrum in real time, but you do not know how to detect the recording parameters in this case. Is there a good way to achieve the desired effect like webaudiodemos. appspot. comAudioR?
