About

SL Prism

Read full description

SL Prism is a precise, fast, touch-ready equalizer for corrective mixing and creative sound shaping. Create a band directly on the spectrum. Move it to set frequency and gain, then refine Q, filter shape, channel routing, dynamics, threshold, attack, and release. Every enabled response stays visible while you work. Use dynamic EQ to control frequencies only when they become a problem. Enable spectral processing for more focused reactions. Switch between Zero Latency, Natural Phase, and Linear Phase modes to match recording, mixing, and phase-sensitive work. Features: • 24 independent EQ bands • Nine filter types • Dynamic and five-slice spectral processing • Stereo, Left, Right, Mid, and Side routing • External sidechain support in compatible hosts • Realtime input, output, masking, and combined analyzers • EQ Match and resonance suggestions • A/B comparison, Undo, Redo, Auto Gain, Pan, Phase Invert, and Mix • Factory effects including Underwater, Telephone, Airy Vocal, Warm Vintage, and Lo-Fi Radio • AUv3 plugin and standalone app • Scalable interface for iPad Audio is processed locally on the device.
