Quantifying auditory perception of blending between sound sources is a relevant topic in music perception, but remains poorly explored due to its complex and multidimensional nature. Previous studies were able to explain the source-level blending in musically constrained sound samples, but comprehensive modelling of blending perception that involve...

The acoustic output signal of orators and singers contains information from the voice source as well as from the articulatory organs. The extraction of formants to achieve information about voice timbre and vocal-tract configuration is among the essential methods in speech and language processing as well as in singing-voice research. However, the v...

Broadband excitation introduced at the speaker’s lips and the evaluation of its corresponding relative acoustic impedance spectrum allow for fast, accurate and non-invasive estimations of vocal tract resonances during speech and singing. However, due to radiation impedance interactions at the lips at low frequencies, it is challenging to make relia...

Perceptually convincing auralization of joint musical performances requires an accurate representation of individual source signals. Recording instruments in anechoic environments typically lack the natural and intrinsic characteristics of joint performances due to limited room acoustic and inter-musician feedback. An alternative is to use close mi...

The blending between sound sources is an important attribute relevant in current acoustic research disciplines such as evaluation of the sound field of an orchestra/ensemble in real or VR domains, and adaptation of stage/room acoustics. Recent studies reveal that the room acoustic characteristics significantly influence the blending impression. Thi...

Many and great efforts have been put into creating anechoic recordings of symphony orchestras, opera arias, solo instruments, speech and etc. However, chamber music, a typical music formation is poorly represented in the available anechoic material library. This is especially relevant in the context of small concert halls, where typically the most...

Vocal tract resonance (a consequence of vocal tract geometry) is an acoustic feature relevant in fields such as speech and singing research, speech therapy, and language learning, but is not easily measured directly (at least, not ethically). In one widely used approach ('ACUZ' [1]), vocal tract resonances are estimated using a sophisticated labora...

Eliciting accurate and acoustically meaningful vocal tract information directly from speech sounds in real-time remains difficult, exacerbated by the fact that the voice itself-with harmonic resolution of >100 Hz-samples the frequency domain poorly. Consequently, methods extracting information directly from [radiated] speech sounds offer only limit...
