Abstract

Stereophony is a method of sound recording and sound reproduction that uses two separate audio channels, two for each process. In contrast, monophony uses only one audio channel. Stereophonic sound is thus affine, to some degree, to human binaural hearing because it can reproduce some of the ambience and localization cues that were present during the recording session. For this reason, stereophonic music recordings are generally preferred over their monophonic counterparts. To make the sound of monophonic recordings more natural, many pseudo-stereophonic techniques have been developed; these techniques process monophonic sound into stereophonic sound. In this thesis, we review in detail five such techniques, of which we implemented and tested two. Our results show that pseudo-stereophony, when applied appropriately, can create more natural nuances in monophonic recordings and can reduce listening fatigue.

Secondary title:	Pregled izbranih metod za psevdostereofonijo
Secondary abstract:	Stereofonija je metoda, ki uporablja dva ločena zvočna kanala, bodisi za snemanje bodisi za predvajanje zvoka. V nasprotju z njo monofonija uporablja le en zvočni kanal. Iz tega razloga je stereofonski zvok do določene mere podoben človeškemu binavralnemu sluhu, saj je sposoben poustvariti nekatere izmed prostorskih in lokalizacijskih namigov, ki so bili prisotni med snemanjem. Iz omenjenih razlogov so stereofonski glasbeni posnetki bolj zaželeni kot monofonski. Z namenom zmanjševanja nenaravnosti monofonskih posnetkov je bilo izumljenih več psevdostereofonskih tehnik, ki so sposobne pretvoriti monofonski posnetek v stereofonskega. V tej diplomski nalogi smo najprej podrobno pregledali pet psevdostereofonskih tehnik, izmed katerih smo dve implementirali in podrobno testirali. Naši testi so pokazali, da premišljena uporaba psevdostereofonije dejansko lahko ponudi naravnejšo izkušnjo pri poslušanju monofonskih posnetkov in zmanjša utrujenost poslušalca ob daljšem predvajanju glasbe.
