Why? A “clean” noise profile helps you analyze problems more easily. This span must be separate from the sound effect you want to save. The noise profile is a guide that divides the poor audio (the profile) from everything else you want to save. The noise profile is a “template” that tells the software what should be removed. One of the most difficult aspects of restoration is finding a clean span of problem audio, called a noise profile. I suggested mastering as you record sound effects last year. Set them aside for later, plan ahead, or tinker with better software. Watch for these challenging sounds when you begin your restoration career. Noise extraction follows a bit too slowly, resulting in a brief breath of noise after steep drops in audio. Algorithms struggle to match big spikes of audio.
Sound effects with diverse dynamic are hard to denoise. Breathy sounds become thinner more quickly. Also, drastic denoising affects these sounds more. What about the sound effect itself? Sibilant, swelling, and breathy sounds are more challenging to denoise. Software may compensate for this with “adaptive” settings. Adjusting a microphone creates image shift, which varies the spread of audio abruptly. HVAC and fluorescent light buzz seem constant, but actually cycle rapidly. Some examples include cyclical problem sounds, like the swell and ebb of distant surf. The job becomes increasingly difficult the more this alters. A steady thickness of noise, or pitch of hum is easier to identify, and to extract. Some of it has to do with the problem audio itself.Ĭonsistent damaged audio is easier to work with. Part of this has to do with the nature of the sound effect.
