Sound card settings

Recently, we are experiencing a great dealEt voice chat software, Http://et.sdo.com/feel et (easy to chat) voice sound quality is quite good, there are low sound quality (8 kHz voice) and high quality (kge 44.1 kHz stereo). You can download this software to experience it.

Nowadays, there are a lot of software related to network speech, which is favored by the majority of children in the 90 s. When you are playing this kind of software, you can first briefly understand the settings of the relevant sound card.

 

The following uses an ac97 sound card as an example. The operating system is a Simplified Chinese version of Windows XP SP2.

Double-click the Speaker next to the input method. The following window is displayed. If you cannot see the small horn icon, open the control panel-sound and audio devices-and tick the volume icon in the taskbar.

Figure 1 shows that the volume control window contains four items and you can adjust the volume. How can I increase or decrease projects here? For example, the newly installed system does not have the microphone volume adjustment option. If you want to display the microphone volume control in this window, click the properties of the option menu. The following window appears after clicking the properties: figure 2 select "play", the available volume control options will appear in the list below, and the checked items will appear in the volume control window after being determined, items that are not checked will not appear in the volume control window in Figure 1. After selecting the microphone, click OK to return to the "volume control" window. Then click the option to find an additional "Advanced Control" option and check it, the "advanced" button will appear below the microphone: Figure 3-point open Advanced button, you can enhance the microphone volume. If the voice is small in the past, the microphone will increase immediately after reinforcement. Figure 4 now click the option menu in Figure 1 again, select properties, and click recording in the Properties window: Figure 5 select "Recording ", the record control options will appear in the following list. After the checked items are determined, they will appear in the record control window. The items not checked will not appear in the record control window in Figure 1. If the HD sound card is used, the "Recording" is gray and cannot be selected. See figure 2. Here, the meaning of stereo mix is stereo sound mixing. Some sound cards may also be wave out, or Chinese audio sound mixing. The titles are different, but the meanings are the same. In the recording window, stereo sound mixing and microphone are required. Click OK and the "Recording Control" window appears: Figure 6 selects the stereo sound mixing (Stereo mix) when you need to play songs or sing karaoke, and selects the microphone when chatting and speaking. If you just want to know how to set up, please refer to the following three pictures, set by picture to achieve the desired effect: 1. Set the sound card during chatting: Figure 7 2, just play the song, sound card settings when others cannot hear the voice: FIG 8. Sound card settings when singing karaoke: Fig 9 Sound card setting principle (it is very important to set most sound cards after understanding)

Applicable to All HD sound cards and ac97 sound cards. Let's talk about several definitions:

Stereo Sound mixing: In the sound card settings, the sound mixing (Stereo mix) means that all sounds are mixed, and the sound produced in the computer is mixed.

Sound output: Sound output refers to the output to the network or external device orProgramSuch as chatting rooms and other network tools, recording equipment, and recording software.

Recording Control: In fact, the real meaning of recording control is what sound channel is used for sound output.

Waveform volume: Generally, the sound sent by the software player in the computer is converted to WAV volume, which is output in the form of waveforms. Therefore, the waveform volume is actually the volume of the sound sent by the player. If you don't believe it, try it, how can I adjust the waveform volume while playing a song on any player?

After the definition is finished, we will talk about the principle. When the microphone is selected in the recording control window, only the sound collected by the microphone is output. At this time, you can only hear the voice of a voice, but not the sound of a song. When the recording control selects the stereo sound mixing, all the sounds in the computer are mixed and output. In this way, you can hear the sound of singing.

However, after stereo sound mixing is selected, which sounds will be mixed, and how can I adjust the volume of audio added to the Mixed Sound through different channels? At this time, the volume control interface is used to adjust the volume. On the volume control page, devices that have been muted do not collect and mix sounds. The sounds collected through different channels are adjusted by the volume control items. Therefore, if the microphone is muted at this time, you can only play songs without listening to the speech, and the adjustment of the waveform volume and microphone volume determines the comparison of the two volumes in the mixed sound, for example, if the music is loud, the waveform volume should be lowered. The total volume output after mixing is controlled by the volume of the stereo sound mixing.
