Microphone and Synthesizer Catalog
Comprehensive hardware catalog covering microphone polar patterns, dynamic / condenser / ribbon mic classifications with major models from Shure, Neumann, AKG, Sennheiser, DPA, Schoeps, Royer, and others; USB and wireless variants for podcasting and live; and the synthesizer landscape — vintage analog classics, modern analog hardware reissues, digital synths, wavetable, FM, Eurorack modular ecosystems, drum machines/grooveboxes, clonewheel organs, and modern stage/workstation flagships.
1. Microphone Polar Patterns
- Omnidirectional — picks up equally from all directions; no proximity effect; common in measurement mics, omni small-diaphragm condensers
- Cardioid — heart-shaped pickup, rejects rear; most common pattern for live vocals and studio
- Supercardioid — tighter front pattern, small rear lobe; popular for live vocals in high-bleed environments
- Hypercardioid — even tighter, larger rear lobe; often paired with shotgun designs
- Figure-8 (bidirectional) — front and rear equal pickup with deep side null; ribbons natively figure-8; large-diaphragm condensers via dual capsule
- Shotgun (lobar) — interference-tube design; long narrow pickup for film/broadcast
- Switchable — large-diaphragm dual-diaphragm condensers (U 87, C414) selectable omni/cardioid/figure-8/wide cardioid/hypercardioid
