Sounds samples of two simultaneous harmonic complex tones

Two simultaneous harmonic complex tones composed of spectral components generated with sine starting phase or random starting phase. The lower fundamental frequency of the tones is 261.1 Hz (the forth octave of the musical scale, C4). The harmonic complex tones are composed of the fundamental and nine higher harmonics. The amplitude of the harmonics in each of the complexes decreases by 6 dB per octave.
