Impulse-response Measurement Excitation Generator

ZIP includes excitation.wav and parameters.json. MLS ignores duration/fade and uses exact (2^order − 1)-sample periods. Impulse has exactly one nonzero sample and no fade. Logarithmic mode requires end > start and at least 1 second; it includes a normalized reverse sweep inverse.wav encoded as float32 to preserve gain. This is an excitation package, not a recorded or measured IR. Lower amplifier and headphone volume before playback; no automatic playback. Levels are peak targets from −60 to −3 dBFS, not calibrated dB SPL. PCM24 WAV uses an exact frame count rounded from duration × sample rate. Periodic frequencies must stay below 0.45 × sample rate. Square, triangle and sawtooth waves use at most 16 harmonics below that limit with conservative peak normalization. Fades may occupy at most half the active signal. Noise and silence ignore frequency, phase and sweep controls. Excitation is a test input, not a measured room impulse response; a separate recording and deconvolution stage is required.
