Oboe-like timbre and spectrally limited tones are used to test interval perception

Evidence

All tones making up the pitch sequences were harmonic complexes, consisting of the first four harmonics of the nominal pitch, exponentially decreasing in amplitude (1:1/2:1/4:1/8) to give an oboe-like timbre. Tone duration was 110 ms, with 5 ms onset and offset linear ramps and 40 ms silence between tones, giving a tone onset to onset interval of 150 ms. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5298
