Influence of Early Recording and Playing Devices on Voice Sounds: Modification of singing voice formants
* Presenting author
Historic voice recordings suffer from numerous artefacts such as bandwidth limitations, noise and distortions. Apart from these unwanted effects voice signals also exhibit changes in the timbre due to interaction of the the uneven transfer characteristics with voice formants. Such modifications are responsible for the characteristic timbre of historic recordings and could help to explain why some singers could profit from timbre changes induced by the recording technology. This paper describes the effect of the interaction of device transfer functions and voice formants. Our approach is the analysis and perceptual evaluation of timbre changes of singing voice signals due to modelled transfer functions based upon simple resonators as found in the acoustic path of historic recording devices.
