![]() ![]() ![]() There are also other factors that deteriorate OC reception, such as the quiet zone, to which we will devote another issue. HPF: Frequencies at which low frequencies are cut in the reverberation (low-cut filter).LPF: Frequencies from which the high frequencies are cut in the reverberation (high cut filter).Low ratio: Determines whether the reverb has a strong low frequency effect.Hight ratio: Determines whether the reverb has a strong high frequency effect.Aangezien Audacity slechts één audioapparaat tegelijk kan opnemen, kunt u het dus proberen als u tegelijkertijd computergeluid en microfoonaudio opneemt Aiseesoft schermrecorder. Regarding the radio, several settings must be taken into account, namely: Alternatief voor Audacity om audio op te nemen. Reverb can be of several types – natural, spring or digital. Reverberation is usually created from a complex amalgam of echoes (called “reflections”), making the effect homogeneous and diffuse and whose evolution over time is modulated according to the frequency and specific settings. The receiver antenna responds to only one type of polarization including automatic amplification control, which helps to attenuate extraneous noise and amplify the sound.Ī few words about reverberation which is the product of the reflection of sound on the different walls and surfaces of an enclosed space. To reduce the effect of fading, one can use directional antennas, or combine a vertical antenna and a horizontal antenna. The polarization also changes following the modification of the concentration of the ionosphere under the impact of the Sun, for example. Another cause of the appearance of fading – the action of the Earth’s magnetic field on the ionosphere following which the polarization of the reflected wave outlines a rotational movement around its own polar axis. It is in most cases the interaction of two or more electromagnetic rays or a rotation of the polarization of the reflected wave. It most often affects short waves and consists of a gradual, sporadic or prolonged weakening of a transmitted signal to the point that it becomes incomprehensible and inaudible. The most unpleasant impact is that of fading, followed by sound reverberation and the zone of silence.įading can be caused by the weakening of broadcast signals or certain atmospheric or electromagnetic disturbances. Listening to short waves /OC/ often gives rise to many phenomena that degrade the quality of sound /speech and music/.
