Audio can add a lot of energetic and interesting elements to the courseware, self-recording dubbing, cutting and stitching music, sound retouching, audio synthesis, and using audioStudio to create audio files suitable for courseware. The following system home Xiaobian for everyone to share how to add audio to the courseware. The audio in the courseware plays an important role in the teaching content. It not only increases the realism of the courseware, enhances the artistic appeal of the courseware, and improves the expressiveness of the courseware. It plays an important role in improving classroom efficiency and promoting students' all-round development. The audio in the courseware is usually used as background music, text recording and special sound effects (such as thunder, rain, etc.). In addition to downloading directly from the Internet, many of these audios need to be produced by yourself, even if they are ready-made audio materials. Also make appropriate modifications according to the actual situation. Stitching the music music in line with the situation can highlight the atmosphere, emphasize the difficulty of teaching, is the most concise and natural way to spread information, and the addition of various effects sounds makes the courseware more energetic. However, music can't be copied in its entirety, and it can be applied directly to the courseware. Many times we may need the best part of one or more pieces of music and decorate them to get the music that fits the courseware situation. Step 1: Open the VideoStudio and click the “Import Media” button to import the desired music files into the “Library” & rdquo; (Figure 1). Drag and drop the music files that need to be cropped to the “audio track”, play the music will “play the ruler” and stay at the place where you need to crop, click the “split material” button to split the file into two parts. Right-click on the unwanted part and select “Delete”. In this way, multiple music files can be dragged and dropped onto the sound track, cropped and deleted and stitched together. When splicing music, pay attention to the unity of the rhythm of the music before and after the transition, try to ensure natural smoothness during the transition. Step 2: If there is a big change between the two adjacent pieces of music, you can slow down by fade in and out. Select the music file on the track and click “Library”“option in the lower right corner" Button, modify the properties of the audio file (Figure 2), click the "Fade in" or "Fade out" button, you can add the fade effect to the currently selected audio, very simple. This effect is usually applied to the background music of the course cover. After the music cropping is finished, click the “Share” button and click “Create Sound File” to save the music as wav or wma format. The wav file has good sound quality and wma sound quality is slightly weakened. Small size, I recommend to choose wma format. Different music may have different volume levels. After splicing, there may be a phenomenon in which the volume is high and low, and the volume of each piece of music can be adjusted to make them basically the same. In order to splicing the music in the context of the situation, on the basis of selecting the material, it is necessary to adjust the decoration several times. If possible, please ask the music teacher to help you listen, so as to ensure the music is natural and smooth. In addition to direct access, the audio in the dubbing courseware required for self-recorded courseware needs to be recorded as needed. For example: the compliment in the courseware, the text scores … … as long as you have a microphone, in the VideoStudio X4 The audio required in the courseware can be recorded. Step 1: Before recording, choose a quiet environment to ensure that the outside noise is as small as possible and the microphone is normally recorded. If you are using Windows 7, you can right click on the “Volume” icon in the lower right corner of the desktop and select “Record”. Device & rdquo; appears in the window (Figure 3), select "Microphone" and click the "Properties" button below, in the "Level" option to adjust the volume of the microphone, switch to the "Enhance" option , select <;DC offset elimination & rdquo; and & ldquo; noise suppression & rdquo; option, which can improve the sound quality. Step 2: In order to improve the success rate of the recording, the content of the recording should be familiar in advance, so as to ensure that the recording will not be mistaken. If the recording still has a soundtrack, it is best to listen to the soundtrack for practice, which is perfect for recording and soundtrack. During the recording process, the soundtrack is played through the digital player and listened to with headphones, so that it does not interfere with the recording. Click the “Record/Capture Options” button on the track to display the dialog box (Figure 4), double-click “Draw a voiceover” and the “Adjust Volume” window will appear. Click the “Start” button to record. Step 3: After the recording is finished, clicking on the sound track stops the recording and the recorded audio file is automatically added to the track. Since it is not recorded in the studio, there will inevitably be noise in the recording. Right click on the audio file and select “Audio Filter” to display the dialog box (Figure 5). Double-click “NewBlue Noise Suppressor” to add to the audio. , then click the “options” button to adjust the noise reduction intensity, you can adjust while listening, and remove the noise as much as possible. After noise reduction, the dubbing may appear a bit thin, and you can add the “NewBlue Audio Touch” filter to make the dubbing mellow and magnetic. Finally, you can drag and drop the soundtrack file to “music track#1”, drag the soundtrack to adjust the start time and synchronize it with the recording. The original audio image in the replacement image is also the material commonly used in the courseware. In many cases, the original sound in the image may not be what we need. This requires retouching or replacing the original audio, which can be easily used in VideoStudio. Achieve audio and video separation and re-record or add audio as needed. The first step: import the image into the material library and drag and drop it to the “video track”, select the image and right click and select “Split audio”, then the audio file in the image will be added to the “sound” sound. Track > (Figure 6), the selected audio can be deleted, and then re-recorded as needed. Select menu “Setting →Track Manager”You can add music tracks to meet some special needs, such as: making virtual wind and lightning effects, thunder, rain, wind and other sounds will appear at the same time, which requires multiple sounds rail. Step 2: When the image contains multiple tracks, we usually weaken the background music to highlight the foreground audio, which is to reduce the volume of the background music. Select the background music and click the “mixer” button. At this time, the volume adjustment line will appear in the audio file (Fig. 7). Click on the volume adjustment line to display the node. After adding multiple nodes, you can lower the node. Drag so that the audio between the two nodes can lower the volume. By adding nodes, we can adjust the volume of the foreground and background audio at any time according to the performance needs, so that they complement each other and complement each other.
