Synth Brain: Learn Synthesis
Ear Training for Sound Design
$14.99 · Designed for iPad. Not verified for macOS.
Go beyond memorizing knob names. Connect every control to what you hear through visual lessons, A/B listening, hands-on sound-matching labs, and focused ear training.
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
