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.
