Chirp was launched in 2019, and is owned and operated by the founders of BookBub, an online book discovery service. [5] [6] Although Chirp was launched more recently, BookBub and its parent company Pubmark Inc. have been around since 2012, when it was founded by Josh Schanker and Nicholas Ciarelli.
A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal . [ 1 ] It is commonly applied to sonar , radar , and laser systems, and to other applications, such as in spread-spectrum communications (see chirp spread spectrum ).
From 2007-2010, CHIRP partnered with organizations across the country to get licenses from Federal Communications Commission for a low power FM radio in urban areas. In 2009, CHIRP's president and vice president, Shawn Campbell and Jenny Lizak, were invited to the White House to discuss the issue of expanding low power FM radio with President Obama's technology team.

The stationary phase method does not predict or deal with Fresnell ripples, so it is unable to offer any means by which these ripples can be minimized. As an example, the figure below shows a chirp spectrum with T. Δ F =250 obtained for a non-linear chirp aiming to match the Hamming window, using the methods described above. The figure shows ...

Chirp (also known as Asio Limited) was a technology company based in the UK. [1] Chirp was originally a research project from UCL and was incorporated as a UK limited company in 2012. [ 2 ] Chirp specialised in data-over-sound software development kits , [ 3 ] which converted data into audio signals, which could be transmitted to other devices ...
Software-defined radio (SDR) is a radio communication system where components that conventionally have been implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a computer or embedded system. [1]
Digital room correction may involve minimum phase algorithms, to maintain wavefront coherence over the intended frequency range.. The use of analog filters, such as equalizers, to normalize the frequency response of a playback system has a long history; however, analog filters are very limited in their ability to correct the distortion found in many rooms.
