Listen looping is a simple technique: find a section of audio that's hard to understand, and loop it — play it over and over — until you can hear what's being said.
How to Do It
- Load audio into a tool like Audacity or chorusing.app
- Listen normally and find a section you can't quite understand but think you should be able to
- Select that section and put it on loop
- Listen repeatedly, focusing on the specific words and sounds
- Once you can hear exactly what's being said, move on
Why It Works
In natural speech, words blend together, sounds get dropped, and familiar words become unrecognizable at full speed. Your brain needs repeated exposure to learn how to parse these fast, connected sounds. 
Looping gives your ears multiple chances to decode the same section, building the connection between what you hear and what you know.
Tips
- Skip sections where you don't know the words — looping won't help if the vocabulary is unknown. Focus on sections where you know (or think you know) the words but can't hear them.
- If available, check a transcript after you've tried to figure it out on your own (this is basically the same as Intensive Listening)
- For an additional challenge, try Transcription
When to Use It
Listen looping is introduced in Phase 3C and continues to be useful through Phase 6.
