Online simulation of a speaker mounted in an infinite baffle. Simulation is based on the rigid piston model.

Simulation of early reflections from the floor, ceiling and from the wall behind the speaker. Baffle step and speaker directivity are also simulated.

Prediction of the audibility of noise in audio systems with "flat" noise floor from SNR.

There are plenty of tools to display directivity: polar chart, directivity index vs. frequency, sound power vs. frequency, sonogram, parametric frequency response graphs...

Rear wall reflection simulator with speaker cabinet (baffle step) simulation. Some extra notes on baffle diffraction.

Simulation of a sound source between two parallel walls. Frequency response, CSD (waterfall), impulse response.
