Extended version of Speaker Directivity Modeler with room response calculation from radiated sound power and free-field response (direct sound).

Online simulation of a speaker with a flat, completely rigid diaphragm mounted in an infinite baffle.

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.

Excel workbooks for studying speaker directivity. Polar chart, frequency response vs. angle, sonogram (color map).

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