Combining audio
Lesson details
Learning outcome
I can export a completed podcast for listening on other digital devices.
Key learning points
- Imported audio can be combined with recorded audio.
- Audio editing sotware can adjust and layer tracks.
- The combined audio in a project may sound less clear than the individual tracks.
- Audio projects can be exported as a single file for playback on other digital devices.
Keywords
Volume - how loud an audio track is
Export - the process of saving data so it can be used on other digital devices or programmes
Common misconception
Audio tracks have a set volume, meaning they might not be usuable for certain projects.
Even if the volume of a track isn't suitable for your project, audio editing software can adjust the volume so that it plays at an appropriate level.
Teacher tip
Various sound effects can be downloaded to enhance the podcasts. You should put them in a folder that the pupils can navigate to, as this will make the process easier.
Equipment
Pupils need access to audio editing software and hardware that can be used play and record audio. Examples in this lesson use Audacity https://oak.link/audacity
