The quality of your audio can make or break your video, so you don't want to ruin your visuals with poor or distorted sound. To ensure your audio is high-quality, it is important to consider the source, format, and level. When creating your own audio, use professional equipment and software to record and edit it. If you use existing audio, make sure to check the license and terms of use, and give proper credit to the original creators. The format of your audio should be compatible with your video editing software and distribution platform; common formats are MP3, WAV, and AAC. MP3 is a compressed format that reduces file size, but also quality. WAV is uncompressed and preserves quality, but also file size. AAC offers a balanced format with good quality and reasonable file size. Lastly, adjust the level of your audio to match the volume of your video and avoid clipping or distortion by using tools like meters, normalizers, and compressors.
