This article outlines the audio standards when recording and exporting your course on Udemy.
What are Udemy’s minimum standards regarding audio?
To publish your course, each of your course videos must contain audio instructions. We require:
- Good audio quality that is clear and not distracting to students
- Audio that comes out of both channels (left and right)
- Audio is synced to video
What audio issues are considered distracting or low-quality?
Some of the most common audio issues that have the greatest impact on the learner experience include:
- Distortion: An electrical static sound caused by having the gain turned too high.
- Background hiss: A raspy noise within your audio track.
- Left speaker: Audio might come out from the left speaker only if settings do not specify that it should be in stereo.
- Low volume: Volume is inaudible unless the user turns their device settings very high
- Inconsistent volume: Sudden changes in volume levels within a lecture or across the course.
- Muffled sound: Unclear speech due to audio response settings or sound mixing.
Do you allow usage of text-to-speech programs?
Udemy now accepts courses with audio instruction created using quality text-to-speech programs. To be approved in the Quality Review Process, please ensure the audio quality is clear, easy to understand, and that your program can properly pronounce any acronyms and technical jargon used in your course. These courses must be accompanied by dynamic and clearly relevant visuals in accordance with the Video Standards.
