## What is EarMaster?

Ready to develop "golden ears" like a pro audio engineer? Whether you're a music producer, audio enthusiast, or a student dedicated to improving your listening skills, EarMaster is your personal, pocket-sized ear training coach.

We skip the dry theory and get straight to what matters. Through a series of carefully designed interactive training and evaluation modules, you'll master the two most critical skills in audio production: Frequency Recognition and Dynamics Processing.

【KEY FEATURES】

**Frequency Training**
*   Build your intuition for the audio spectrum, from the 6 fundamental bands to hundreds of advanced frequency points.
*   Learn to identify and distinguish the "punch" of sub-bass, the "core" of vocals in the mids, and the "air" of the high frequencies.

**Dynamics Training**
*   Deep dive into the four essential parameters of a professional compressor: Threshold, Ratio, Attack, and Release.
*   Through comparative listening, learn how different settings can shape the punch, breath, and tightness of any sound.

**NEW! Explore Mode**
*   Your personal sound laboratory! Tweak all compressor parameters in real-time within a professional-grade interface.
*   Visualize the changes with a live transfer curve graph and an accurate gain reduction meter.
*   Experiment freely on looping audio sources to perfectly connect theory with practice.

**Evaluation & Records**
*   Test your skills with ABX-style quizzes and challenge your listening acuity.
*   Receive detailed reports with accuracy, response time analysis, and your most common mistakes to pinpoint areas for improvement.
*   Track all your training and evaluation sessions to see your progress over time.

【WHO IS IT FOR?】
