## What is Synth Brain?

Learn synthesis by connecting what you see, hear, and change.

Synth Brain is a step-by-step learning app for understanding synthesizers and sound design through concise visual lessons, A/B listening, hands-on patch labs, and focused ear training.

Memorizing knob names is not enough. Synth Brain connects every control you change with the result you hear. Listen to a target, shape the sound yourself, and check the difference by ear. Follow one structured path from the fundamentals to advanced synthesis techniques.

HOW YOU LEARN
• Concise visual lessons organize the signal flow and the role of each parameter
• A/B comparisons help separate loudness differences from timbral differences
• Hands-on labs let you move the controls toward a target sound
• Ear-training quizzes develop recognition of brightness, attack, beating, modulation, and more
• A built-in synth playground lets you explore each technique freely

CURRICULUM HIGHLIGHTS
• Pitch, loudness, timbre, harmonics, and gain staging
• Basic waveforms, noise, octaves, detuning, beating, and PWM
• Low-pass, high-pass, and band-pass filters; cutoff, resonance, and key tracking
• Amp and filter envelopes, including ADSR
• LFO routing, vibrato, tremolo, wah, and modulation depth
• Patch design for basses, leads, pads, plucks, and drums
• Layering, chorus, delay, and reverb
• FM, hard sync, ring modulation, and additive synthesis

SYNTH BRAIN IS FOR YOU IF YOU WANT TO
• Understand what the controls on a synthesizer actually do
• Move beyond presets and build sounds yourself
• Train your ears for music production and sound design
• Learn foundations that transfer between hardware and software synthesizers

MORE FEATURES
• Japanese and English
• Designed for iPhone and iPad
• No account required
• Learning progress stored on your device
• A safety limiter that reduces sudden output peaks

Protect your hearing and begin at a low listening level. For subtle comparisons, use headphones or wired earphones at a comfortable level.

Turn visible controls into knowledge you can hear.
Start shaping sound with Synth Brain.
