What Are Zero-Crossing Recordings? | Wildlife Acoustics
https://www.wildlifeacoustics.com/resources/faqs/what-are-zero-crossing-recordings
rather than representing the full waveform, or shape, of sound information in the way that most conventional, full-spectrum audio recordings in any application do, zero-crossing is a compact way of representing only the most prominent frequency in a recording by noting the points in time at which a sound wave has crossed a reference amplitude a …

If you do not perform these operations at zero crossings, this can result in discontinuities in the wave, which are perceived as clicks or pops in the sound. Activate Zero-Crossing on the Edit tab of the Audio Editor to make sure that the selections that you make are always adjusted so that they start and end at the nearest zero crossing. 🏠

Zero crossings are a basic property of an audio signal that is often employed in audio classification. Zero crossings allow for a rough estimation of dominant frequency and the spectral centroid (SC) [52]. Zero crossing rate.

It may not appear so at first glance, but a zero crossing detector is a special purpose analogue to digital converter (ADC). In some cases, you can use an uncompensated opamp (such as the LM301) as a comparator, but most 'real' comparators are significantly faster. An LM301 was used as a zero crossing detector in Project 143. Comparators
Audio in to zero-crossing... | AVR Freaks

I want to take an audio signal into a zero-crossing detector, i.e. to signal condition the drive (from an MP3 player typically) then to feed into a ZCS detector using an ATmega which I will use to generate a square wave with leading edge on the -ve -> +ve input transition, and the trailing edge on the +ve -> -ve input transition.

Zero Crossing Rate (ZCR) is a time-domain audio analysis tool that helps us calculate the frequency of monophonic audio. It is a very basic algorithm and I talk a bit about its performance in a...

Zero crossing detector circuit is similar to a comparator but one of the input pins connects with a ground terminal. We provide zero voltage reference to one of the inputs pins. Because we want to find zero crossings of a sine wave. Whenever a sine wave makes the transition from zero reference voltage, we will get a digital high output.
