FIR Designer 1.31

FIR Designer by Radio Consult SRL is a specialized desktop application for creating and validating finite impulse response (FIR) filters used in audio, broadcast, and embedded DSP systems. It streamlines the path from a target frequency response to deployable coefficients, combining an intuitive workflow with precise analysis to help engineers achieve predictable, reproducible results. Whether you’re building crossovers, equalizers, or band-limited filters, FIR Designer provides the tools to move quickly from concept to implementation.

Key capabilities:

• Design common FIR responses, including low-pass, high-pass, band-pass, band-stop, and equalization curves
• Control tap length, sample rate, gain normalization, and windowing for practical, hardware-ready results
• Analyze magnitude, phase, group delay, and time-domain behavior with interactive plots
• Shape phase (e.g., linear-phase or phase-adjusted designs) while monitoring latency and group delay
• Import target responses or measurement data to match real-world devices and systems
• Quantize coefficients to fixed-point formats and apply scaling/dither to suit embedded DSP constraints
• Export coefficients in convenient formats (such as CSV, text, or C/C++ headers) for straightforward integration
• Validate designs against specifications with on-screen metrics and response overlays

FIR Designer helps audio and DSP engineers, educators, and integrators reduce iteration time and deliver filters that meet performance and implementation requirements with confidence.
