Audyssey MultEQ is a leading room correction software solution integrated into numerous AV receivers from brands like Denon and Marantz, using a calibration microphone to measure room acoustics and apply precise digital filters for frequency and time-domain corrections. It offers variants like MultEQ XT32 for higher resolution and the MultEQ-X app for post-calibration editing of EQ curves, dynamic EQ, and more. This system delivers immersive, accurate audio tailored to room imperfections, supporting setups from stereo to full home theater.

Room EQ Wizard (REW) is a free, open-source software suite for acoustic measurements, analysis, and room correction, allowing users to capture detailed room response data using a calibrated microphone and audio interface. It provides comprehensive tools for generating parametric EQ filters, FIR filters, and convolution files to correct frequency response issues, modal resonances, and decay times. Popular among audiophiles and professionals, REW excels in diagnostic depth but requires technical know-how to fully utilize.

Anthem ARC Genesis is a professional-grade room correction software tailored for Anthem AV receivers and processors, using a USB microphone to capture multiple room measurements for analyzing frequency response, impulse response, and decay characteristics. It generates advanced correction filters, including parametric EQ, linear-phase FIR filters, and precise subwoofer integration, to optimize audio playback in any listening environment. The software provides detailed graphical analysis and exportable filters for fine-tuning home theater setups.

Acourate is a professional-grade room correction software that performs precise acoustic measurements using logarithmic sine sweeps to capture room and speaker responses. It generates high-resolution FIR and IIR filters optimized for frequency and time-domain correction, supporting complex multi-channel setups including multi-way speakers and subwoofers. Designed for Windows, it exports filters for use in convolvers like JRiver or Foobar2000, enabling detailed control over audio reproduction.

Audiolense is an advanced room correction software that uses logarithmic sine sweeps to measure room acoustics and generates high-resolution FIR filters for precise frequency and time-domain corrections. It excels in multi-channel setups, supporting up to 24 channels, multiple subwoofers with individual delays, and integration with convolution engines like those in JRiver or hardware such as miniDSP. Designed for audiophiles and professionals, it offers extensive customization for speaker and listener position optimization.

SoundID Reference by Sonarworks is a professional audio calibration software designed to correct the frequency response of studio monitors and headphones for accurate mixing and mastering. It uses a measurement microphone to analyze room acoustics and speaker interactions, generating custom correction filters applied via plugins, system-wide, or standalone app. The software also features an extensive library of headphone profiles, allowing users to achieve reference-standard monitoring across setups.

ARC 3 by IK Multimedia is an advanced room correction software that uses a measurement microphone to analyze your room's acoustics and generate custom FIR filters to correct frequency response, phase, and decay issues. It applies corrections in real-time through VST/AU/AAX plugins or a standalone system-wide application, improving monitor accuracy for mixing and playback. The latest version introduces a modular Processing Chain for greater control over correction parameters.

Trinnov Optimizer is a professional-grade room correction software from Trinnov Audio, designed for high-end home theaters and studio environments. It uses a specialized 3D calibration microphone to capture detailed acoustic measurements from multiple positions, creating a precise 3D model of the room and speaker interactions. The software then applies advanced FIR and IIR filters, including rotatable filters, to correct frequency response, time alignment, and phase issues across multi-channel systems, with exceptional handling of multiple subwoofers.

rePhase is a free, open-source FIR filter design tool specialized for room correction in audio systems. It allows users to import frequency response measurements from tools like REW and create custom linear-phase, minimum-phase, or mixed-phase FIR filters to correct magnitude and phase distortions caused by room acoustics and speakers. The software provides precise control over filter parameters and exports convolution filters for use in media players like JRiver or Foobar2000.
