SoundRoom

SoundRoom is a professional tool for scientifically measuring and analyzing room acoustics. Using deconvolution (ESS) for high-accuracy RT60 (reverberation time) measurement, it visualizes your room's acoustic characteristics across 6 frequency bands (125Hz–4kHz) and automatically recommends optimal acoustic treatment materials and required coverage area. ■ RT60 Measurement - High-accuracy deconvolution (ESS) method - 6-band (125Hz–4kHz) reverberation time visualization - Ambient noise check (ensures measurement accuracy) - 3-step guided measurement (environment check → level calibration → measure) - Per-band confidence rating & noise floor display ■ Standing Wave Analysis - Automatic room resonance (room mode) detection - 2D heatmap visualization of sound pressure distribution - Drag-and-drop speaker/listener placement simulation - Frequency slider (20–300Hz) for band-by-band inspection - Predicted vs. measured comparison ■ Waterfall Analysis - Time-frequency decay pattern visualization - Automatic decay time calculation across 4 bands - Identifies flutter echo and resonance problem areas ■ SPL Meter - Real-time sound level measurement - A/C weighting support - Leq/Max/Min/Peak display - 30-second graph view ■ Acoustic Treatment Recommendations - Sabine equation-based material suggestions with required area calculation - Treatment simulator (visualize RT60 changes by coverage area) - Complementary material suggestions (fills weak frequency bands) - Real commercially available products: GC board, MG board, SONEX, bass traps, etc. ■ Additional Features - FIR correction filter WAV export (for compatible audio players) - PDF report generation - Before/After measurement comparison - Measurement history management - USB measurement microphone support (UMIK-1, etc.) - Help guide (8 topics: reading RT60, treatment tips, measurement best practices, etc.) ■ Supported Room Types - Home Theater - Hi-Fi Listening Room - Meeting / Control Room - Recording Studio - Podcast / Streaming Room ■ Who Is This For? - DTM / home recording users bothered by room reflections - Home theater enthusiasts looking to improve sound quality - Podcasters and streamers wanting better audio quality - Anyone wanting to know which treatment materials they need and how much ■ Measurement Technology - Deconvolution (ESS) impulse response extraction - Lundeby method noise floor detection - Schroeder backward integration - Welch method FFT for standing wave analysis - Native KissFFT processing ■ Supported Languages Japanese / English / Simplified Chinese
