- In simple terms, noise is a type of visual distortion that affects how pixels look in a digital photograph. It can happen regardless of the type of camera you are using— from mid-range smartphones to expensive DSLRs. Usually, noise makes your photograph appear grainy instead of flat and sharp. Think of an old photograph taken with a film camera.

Guide to FFT Analysis (Fast Fourier Transform) | Dewesoft
- https://dewesoft.com/daq/guide-to-fft-analysis
- FFT is the abbreviation of Fast Fourier Transform. Using FFT analysis, numerous signal characteristics can be investigated to a much greater extent than when inspecting the time domain data. In the frequency domain, the signal characteristics are described by independent frequency components, wherein the time domain it is described by one waveform, containing …

- https://capturetheatlas.com/noise-in-photography/
- Noise in photography is the arbitrary alteration of brightness and color in an image. The onset of this random variation generates what is called “noise”or “grain”, which is basically formed by irregular pixels misrepresenting the luminance and tonality of the photograph. These pixels are visible to the eye due to their large size.

- https://aperlust.com/what-is-noise-in-photography/
- By definition, digital noise in photography is the luminance and color aberrations caused by a digital camera and its image sensor when capturing an image. From a visual viewpoint, noise looks like tiny spots on a picture. All digital photos have some noise in them.
"Noise Floor" and S/N ratio in and with FFT plots - DDDAC

- FFT Example of a noise floor And now comes the real clue: the curve values you see are all kind of small spots calculated by the FFT program. They are called BINs and have a certain width which is depending on the length of the FFT measurement (how many points are you measuring over the audio bandwidth?) and the sample frequency Fs.
