A step-by-step guide to editing audio in DemoCreator

Here is a step-by-step guide about how to edit audio in Wondershare DemoCreator.

Step 1: Download and install the Wondershare DemoCreator program.

To edit audio in DemoCreator, firstly download and install Wondershare DemoCreatore program to your computer. Choose whether your device's operating system is Windows or macOS and click the corresponding 'Free Download' button.

Step 2: Record or import the music files

If you are starting audio from scratch, you can record a new file using your Microphone or any other system sound. However, if you have a pre-recorded audio, click the 'Open File' option to add audio.

Step 4: Drag and drop the audio file into the timeline

Once you settle on which media file to import from your computer, it's time to add them to the DemoCreator timeline. Drag and drop the audio to the timeline and head on to edit your file.

Step 5: Select the audio track and right-click to choose the "Edit Audio".

Select the track by hovering your mouse over the thumbnails of the audio. Then right-click the audio and choose the 'Edit Audio' option from the drop-down list.

Step 6: Drag the mouse over the music track to adjust the fade-in and fade-out duration

Fade-in and fade-out are paramount when editing your audio. Adjusting the fade-out makes the sound progressively softer while fading away until it's no longer heard. Set it, drag the mouse over the music track, push the slider bar to either the right or left, mark the start time and the duration you want it to take.

Step 7: Adjust the audio speed, volume.

You can choose faster/slower speed or high/low volume. In this case, use the right audio panel to adjust the volume. Go to the 'Editing Properties' of the audio file and choose the 'Audio panel' of that specific audio clip. Then select the 'Volume' settings. It is set to 50 by default. Adjust it to the right to raise the volume, or to the left to lower the volume of your audio. That is also how to adjust the video sound.

The 'Time Stretch' feature in DemoCreator is responsible for the speed control. You can either stretch or contract the audio as you wish. Likewise, you can click the 'Speed settings' and specify the speed percentage. Meanwhile, ensure you indicate the duration at which you want that particular setting to be applied.

Step 8: Export and share.

The editing process is accomplished, and now the next thing to do is to export your file. Name your audio and choose a location to store it as an exported file. Likewise, you can adjust the sample rate, bitrate, and channel as per your preferences. Lastly, click the 'Export' button at the bottom of your screen and save the file to your computer. You can now freely share your audio file to YouTube and other channels.
