Audio for Online Course Creators
Updated October 2026
A course is many lessons that must sound like the same teacher in the same room. Set the room and the mic once, record in sections, and clean every lesson with the same settings.
The short version
- Fix the room, the mic and the distance for the whole course.
- Record in sections, and keep a note of the settings.
- Clean each lesson the same way, and check the loudness across lessons.
- Add captions from the transcript for accessibility.
Consistency
Students notice when the sound changes between lessons. Use the same room, mic and distance for every session, and write the settings down.
Sections
Record each lesson in sections, so a stumble is easy to re-record. The lecture voice guide covers the take.
Cleanup and captions
Clean every lesson with the same settings, then check loudness across a few lessons together. Export captions from the transcript and check them against the audio. The teacher routine has the sequence.
