peer agreement (net): +1noise reduction of the original recordings Explanation: Recording takes place in three phases such as pre-production, production and post-production. In the production, tracks are recorded. After that the artist or singer’s voice is recorded on the same track. After the dubbing and editing final mixing/mastering is done. In the post production many things are to done on the mixing console desk. Noise is an important factor to be remembered and taken care of during track lying and editing. In this unit we will discuss on various noise reduction process. We will also focus on audio monitor and its applications. Noise Reduction Any ambience sound that disturbs us in hearing to the main signal is considered as a noise. Noise is the unwanted sound or signal that disturbs our main program, that’s creating an obstacle in our communication. It is one of the most challenging tasks during recording. In audio recording process the noise needs to be reduced and should not overlap the main signal. Noise may be created by so many sources in the room and outside also. In an analog ATR and VTR format, we usually notice so many noises like the tape noise, hissing, through print, humming etc. We will largely focus on reducing tape noise that’s a natural by product of the analog recording or playback process. http://oasis.col.org/bitstream/handle/11599/2860/2018_DMA-05... -------------------------------------------------- Note added at 2 hrs (2019-09-17 14:06:54 GMT) -------------------------------------------------- A strong option: filtering the noise See Sound processing The processing of signal means deliberately modifying or altering the characters of audio signal. There are many processes available like frequency correction, dynamic range manipulation, addition of effects into the main signal etc. In frequency correction we usually modify the frequencies according to the timber or tonal quality of the instruments by judging through our ears and monitor. We may increase or decrease the low bandwidth, mid or high bandwidth as per the demand of the signal. It is wise not to blend or modify the original signal if it is not required. Taking the tracks carefully is much more important than modifying the signal at post production. Levelling of each channels, filtering of the noise, use of SFX or effects, normalize the audio, fade-in, fade-out, cross fade, trimming, panning etc. are the editing tools used for the signal process. Effects like eco, delay, reverberation chorus are applied to specific instruments for a live feeling. Before recording the final audio project all the necessary editing, processing, rectifications need to be done during audio post production. |
