• Audio Quality: Common Issues and Solutions

    There are a few common issues instructors face as their videos go through our Quality Review Process. Learn more about these common issues--and their solutions--here:

    • Distortion: A rasping sound that results from incorrect audio levels.
    • Background Noise: Interference in your audio that distracts from the student experience.
    • Echo: An echo sound results from a recording location that is not optimized for sound.

    If you’re working through audio issues, we highly recommend that you submit a test video first before you record all of your lectures. Once you submit a test video, a Udemy team member will review your audio (and video) recording settings to ensure you are set up for success in the Quality Review Process and the Udemy marketplace.

    Why is Audio Quality Important?

    Great audio quality is critical to ensure students stay engaged in the course without getting distracted and have a pleasant course experience. We surveyed a sample of students and found that 75% felt audio/video quality was absolutely essential to a good course experience.

    What You Need to Know

    • We don’t require specific recording equipment, but we do have recommendations to help you choose! You can find them here: Recommended Audio and Video Equipment.
    • We highly recommend submitting a test video before recording all of your lectures to receive feedback from the Udemy team.
    • Set up a recording area to ensure the highest quality audio. Avoid anything that will cause excessive noise, such as fans, vents, electronic devices, and other people!
    • Before recording, make sure your microphone is plugged in correctly and your recording software recognizes your microphone.
    • Speak clearly and directly into your microphone to avoid any muffled sound.
    • Audio must be clear of distracting noises including: echoes; “pops” on ‘P’ and ‘T’ sounds; background hum; fuzziness.
    • Text to speech software is not allowed, students want to hear directly from you as an instructor to build trust.
    • Audio must be coming out of both channels, and matched to video.
    • All video lectures must have an audio track to walk students through your course content.

    • Turn off any vents or fans in the room, as well as any electronic devices, including your television and your phones.
