How do I combine two audios into one that plays at the same time?

To combine two audios into one, you usually need to use an audio editing software. The specific steps are as follows: 1 Open an audio editing software such as Adobe Audition, Audacity, etc. 2 import the two audio files into the software and select them as input files. 3. Choose the audio track in the software to store the sound data of each audio. 4 Choose the start and end times of the audio tracks to ensure that they are close enough to be played at the same time when merging. 5. Use the "audio mixer''function to combine the frequencies of the two audio frequencies. 6. Adjusts the parameters of the mixers as needed to achieve the desired audio effect. 7 Save the merged audio file and export it to the desired format such as MP3, WLV, etc. It should be noted that when merging the audio, it is necessary to ensure that the sound data of each audio is correct. Otherwise, it may cause abnormal audio effects.
