Sountra

Sountra helps you arrange speakers in a home room before you move the real furniture. Draw a rectangle in meters or feet, then place stereo or theater speakers, a listening seat, furniture, and wall panels. The plan is a 2D canvas. Pinch to zoom, pan, drag, and rotate. Snap to the grid and keep distances in real room units. Undo and redo store one finished move as a single step. Sound Paths draws geometric routes from each speaker to the seat. Direct lines show length and an approximate travel time at 343 meters per second. First reflections use the image-source method on straight walls and report the bounce point, path length, and delay versus the direct sound. A panel that covers the bounce is named on the card. The numbers are geometry, not a microphone measurement. With a stereo pair and a seat, alignment shows both distances, speaker separation, and the listening angle. Treatment…
