SNR measures signal power relative to background noise power. Ratio greater than 1:1 indicates more signal than noise. Affects performance of communication, audio, radar, and imaging systems
Image noise is random variation in brightness or color information. Can originate from sensor, circuitry, film grain, or shot noise. Typical noise is Gaussian, additive, independent at each pixel. Salt-and-pepper noise appears as dark pixels in bright regions
Place microphone 6 inches away from mouth, avoiding direct mouth contact. Use pop filters to minimize breath sounds and sibilance. Adjust microphone gain using built-in dial or Windows volume controls. Close background apps accessing microphone
Online service for noise reduction and background music removal. Available in Starter (10 minutes), Lite (500 minutes), and Plus (750-5000 minutes) packages. Supports multiple audio and video formats including MP3, OGG, WAV, FLAC. Files can be processed up to 2GB in size
Edison plugin removes noise from pre-recorded audio samples. Open Edison via Edit icon or Ctrl/Command + E. Select noise-only section from sample using wavelength or spectral view. Adjust Threshold and Amount knobs to control noise reduction. Save file after denoising process
Lower microphone gain by 1-2 dB to eliminate static background. Check and tighten all audio cables and connections. Move microphone closer to mouth to reduce feedback. Keep electronic devices away from microphone
