Digital audio in radio production
This subtopic covers the fundamental principles and practical skills of digital audio production for radio. Learners will explore technical aspects such as sample rates, bit depth, and file formats, and develop hands-on proficiency in using audio editing software to record, edit, and export audio content suitable for broadcast.
Assessment criteria
Learning Objectives
What you need to know and understand
- Explain the impact of sample rate and bit depth on audio quality
- Demonstrate correct setup of recording equipment for digital capture
- Apply editing techniques such as trimming, fading, and noise reduction
- Manipulate audio using effects like EQ, compression, and reverb
- Export audio in appropriate formats for radio broadcast
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for correctly identifying sample rate and bit depth settings in a project
- Award credit for demonstrating proper microphone placement and level setting during recording
- Award credit for using non-destructive editing techniques in the software
- Award credit for applying effects that enhance clarity and meet broadcast standards
- Award credit for exporting files with correct metadata and format specifications
Assessment Guidance
Guidance for achieving higher grades
