I'm unable to listen to audio, so I can't identify the type of triad you're hearing. However, I can help explain the characteristics of each type of triad:
- Major Triad: Has a bright and happy sound, consisting of a root, major third, and perfect fifth.
- Minor Triad: Sounds more somber or melancholic, made up of a root, minor third, and perfect fifth.
- Augmented Triad: Has a tense and unresolved quality, created from a root, major third, and augmented fifth (which is a raised fifth).
- Diminished Triad: Has a tense and unstable sound, formed from a root, minor third, and diminished fifth (which is a lowered fifth).
If you can describe the sound, I can help you determine which triad it might be!
