The film industry or motion picture industry comprises the technological and commercial institutions of filmmaking, i.e., film production companies, film studios, cinematography, animation, film production, screenwriting, pre-production, post-production, film festivals, distribution, and actors. Though the expense involved in making films almost immediately led film production to concentrate under the auspices of standing production companies, advances in affordable filmmaking equipment, as well as an expansion of opportunities to acquire investment capital from outside the film industry itself, have allowed independent film production to evolve. In 2019, the global box office was worth . When including box office and home entertainment revenue, the global film industry was worth in 2018. Hollywood is the world's oldest national film industry, and largest in terms of box office gross revenue. Indian cinema is the largest national film industry in terms of the number of films produced, with 2,446 feature films produced annually . The worldwide theatrical market had a box office of in 2019. The top three continents/regions by box office gross were: Asia-Pacific with , the U.S. and Canada with , and Europe, the Middle East and North Africa with . , the largest markets by box office were, in decreasing order, the United States, China, Japan, South Korea, the United Kingdom, France, and India. , the countries with the largest number of film productions were India, Nigeria, and the United States. In Europe, significant centers of movie production are Italy, France, Germany, Spain, and the United Kingdom.

In this notebook we will explore various ways to implement a system
that changes the voice of a speaker. Typical applications for these
techniques, strictly sorted by plausibility, include international spy
missions and prank telephone calls, and devices such as the one
displayed here can be easily bought on the web... or in a novelty shop.

The Karplus-Strong algorithm is a simple method to generate synthetic
sounds with arbitrary pitch. In this notebook we will explore a few
variations of the method to illustrate some basic notions of
discrete-time signal processing.

In this notebook we will use the adaptive LMS filter to estimate the
impulse response of a reverberating room.
A typical use case is handsfree telephony: since the received signal,
amplified and played by the speaker, is picked up by the microphone, we
need to eliminate it from the signal that is transmitted back in order
to avoid a feedback loop. The signal picked up by the microph "I defy anybody to find a record... unless it is some old blues
record from 1922... that uses feedback that way. So I claim it for
the Beatles. Before H
