We provide software tools for equalizing audio systems and creating custom finite impulse response (FIR) filters & complete mixed FIR + IIR filter loudspeaker presets for single and multi-way loudspeakers.
Products in the Eclipse Audio range share an intuitive workflow that uses imported loudspeaker measurements as the starting point for filter & preset design.
Both macOS and Windows versions of all products are available. Download a free demo version of any product & use for as long as you’d like.
