Frequency response is the quantitative measure of the output spectrum of a system or device in response to a stimulus, and is used to characterize the dynamics of the system. It is a measure of magnitude and phase of the output as a function of frequency, in comparison to the input. In simplest terms, if…

    Sonic Visualiser 1.0 showing a waveform pane and a melodic range spectrogram pane. (The music is “After the Pain” by Carlos Pino.) Overlaid on the spectrogram is a note layer, showing the output of a note-tracker Vamp plugin that is being evaluated. The notes from the tracker are played using a piano sample,…

    . Introducing signals In electronic circuits things happen. Voltage/time, V/t, graphs provide a useful method of describing the changes which take place. The diagram below shows the V/t graph which represents a DC signal: via signals.

Dynamic range compression, also called DRC (often seen in DVD and car CD player settings) or simply compression reduces the volume of loud sounds or amplifies quiet sounds by narrowing or “compressing” an audio signal’s dynamic range. Compression is commonly used in sound recording and reproduction and broadcasting.[1] The dedicated electronic hardware unit or audio…

In common use, the word noise means any unwanted sound. In both analog and digital electronics, noise is random unwanted perturbation to a wanted signal; it is called noise as a generalisation of the acoustic noise (“static”) heard when listening to a weak radio transmission with significant electrical noise. Signal noise is heard as acoustic…

The Fletcher–Munson curves are one of many sets of equal-loudness contours for the human ear, determined experimentally by Harvey Fletcher and Wilden A. Munson, and reported in a paper entitled “Loudness, its definition, measurement and calculation” in Journal of the Acoustic Society of America[1]. via Fletcher–Munson curves – Wikipedia, the free encyclopedia.

An overtone is any frequency higher than the fundamental frequency of a sound. The fundamental and the overtones together are called partials. Harmonics are partials whose frequencies are whole number multiples of the fundamental including the fundamental which is 1 times itself. These overlapping terms are variously used when discussing the acoustic behavior of musical…
