How to Improve the Audio in Your Marketing Video
What makes a marketing video’s audio track sound good is largely in the eye (or ear, rather) of the beholder. Some people like strong bass and loud effects, and others prefer subtle and sophisticated soundtracks.
Virtually any type of soundtrack can benefit from these tricks:
Use the equalizer to coax out the character of every sound. For example, the sound of rolling thunder recorded on your camera’s cheap, built-in microphone may sound thin and unimpressive. Boost the low frequencies to highlight the thunderous power of Thor. Or if you have an outdoor interview recording with a lot of wind noise, turn down the low frequencies to highlight the voice more clearly.
Use automated features such as the Normalize Clip Volume button in your editing program. This button can help eliminate basic sound issues.
Use the Loudness equalizer setting on music tracks. This setting is designed to make music sound better if it’s played at a relatively low volume, which many viewers are likely to do.
Use fades. Cutting audio isn’t easy because a hard cut in the middle of a sound can appear quite rough and choppy. Use the fade-in/fade-out functionality in your editing program liberally to make the sound more fluent.
Use a compressor. Available in many advanced editing programs, a compressor reduces the dynamic volume differences in a soundtrack and increases the volume of the average sound — typically a benefit, particularly if viewers watch your video on a laptop or mobile phone.
