Database of acoustic and psychoacoustic stimuli

This collection provides a set of commonly used synthetic audio signals for acoustic measurements and psychoacoustic research. It consists of sine tones, harmonic complex tones and narrow-band noises at ISO 266 frequencies as well as noise stimuli with specific spectral properties (uniform-exciting noise, equally-exciting noise, uniform-masking noise, CCITT noise, critical-band wide noise, pink noise, white noise) and specific temporal properties, like noise bursts and pulse trains. Calibration signals are also provided.
