question: Why do big interviews have to have 50 microphones from each media outlet listening as opposed to just one microphone that everyone there can receive an audio file from?
comment: Both techniques are used. Highly professional venues have the technicians and equipment needed to set up a shared mic system. Other venues don't have that.
passages: Since broadcasters need their video files at all times in a world of 24-hour news, and since there are more of them needing such access, the ability to retrieve such files instantly is no longer a luxury. Sharing of systems cuts costs and allows data to be backed up in the event a possible problem is detected.

   The built-in microphone in smart speakers is continuously listening for "hot words" followed by a command. However, these continuously listening microphones also raise privacy concerns among users. These include what is being recorded, how the data will be used, how it will be protected, and whether it will be used for invasive advertising. Further, an analysis of Amazon Alexa Echo Dots showed that 30–38% of "spurious audio recordings were human conversations", suggesting that these devices capture audio outside of strictly after hot word detection.

   A media lock-up held by the Government of Canada in January 2015 prior to the tabling of an anti-terrorism bill was criticized by attendees, who were denied access to the bill ahead of the press conference.
  
  In 2011 author Nicholas Russell wrote that media lock-ups "may do more good than harm" by providing journalists with "thinking time" on complex matters. He also wrote that "It can be argued that the lock-up system leads to wholesale homogenization of the news - everyone gets basically the same story."
   Commercial audiovisual can sometimes be a very lengthy process to get it right. Boardroom audio visual can be installed for a number of reasons, but usually, it is because the executives of the organization/business wants to have meetings with colleagues/customers/suppliers around the world. When creating an array of boardrooms for customers it has been seen that you have to be able to balance the pattern from the audio and microphone so there is no interruption in the sound quality for the individual/s listening in.
   On 28 November 2012, the Channel 4 documentary "Taking on the Tabloids", fronted by actor and phone hacking victim Hugh Grant, showed footage from a 2003 interview with Morgan by the singer and phone hacking victim Charlotte Church, during which he explained to her how to avoid answerphone messages being listened to by journalists. He said: "You can access ... voicemails by typing in a number. Now, are you really telling me that journalists aren’t going to do that?"
   Microphones are often designed for highly specific applications and have a major effect on recording quality. A single studio quality microphone can cost $5,000 or more, while consumer quality recording microphones can be bought for less than $50 each. Microphones also need some type of microphone preamplifier to prepare the signal for use by other equipment. These preamplifiers can also have a major effect on the sound and come in different price ranges, physical configurations, and capability levels. Microphone preamplifiers may be external units or a built in feature of other audio equipment.

   To create a personalized audio message, individual audio segments must be recorded and later reassembled to create one complete, cohesive message. Common first names are first identified and then recorded in succession. These audio segments are then merged with a message greeting and body that addresses a particular topic. The final result is one fluid message that recipients can download, access, or receive for listening purposes. By recording segments individually, recording times can be significantly reduced.
  
  Section::::Current use.
   It is also possible to determine the type of microphones according to the direction of the action. There are narrowly and broadly directed. If there is a large conference hall with the presence of a large number of participants and speakers, then the narrowly directional microphones are the best choice, since each of the microphones has a limited perception zone and will not perceive the voice of the other speaker. If a room is small and there is an opportunity to put a microphone in the middle of the table, then the wide directional mic can be used.
   Journalists call into the conference to ask their questions. This saves time and money for the personality being interviewed as there is no need for them to move from one location to another. This is used more and more frequently, for example during times of crisis when organizations use their communications department to keep people informed.

   Personalized audio messaging
  
  Personalized audio messaging is the compiled, personalized voice messages that individually address recipients by name. These voice messages can be delivered through a myriad of channels, the most popular of which include phone transmission, email, web, and social media sites such as Facebook. Traditionally these messages are recorded by recognizable figures or people of notoriety to enhance the impact the message has on its audience. Because of demanding schedules, automated computer systems are generally used to help compile separate recordings by the recorder, to reduce recording times.

  IVRs are reliable methods of taking exit interviews because they are accessible by phone, a very widespread and reliable technology. However, IVRs have fallen out of favor due to the cost effectiveness of web based options that yield data at similar or higher quality. In comparison to other options, it is difficult to get rich data from an IVR, or to adjust and change it, since any changes require new voice recordings to be made.

   The speech databases recording campaigns continue having moved on from Europe to Mediterranean countries, to the South, Center and North America and, finally to countries in the Far East. Overall countless hours of speech have been recorded by contacting hundred of thousands of people in the listed regions. The recordings have been collected both for fixed telephone networks, as well as in moving vehicles for mobile phones and also using high quality microphones in domestic environments for consumer applications such as video games, appliances and home automation in general.
  
  Section::::History.:Speaker recognition.
   There are strong concerns that the ever-listening microphone of smart speakers presents a perfect candidate for a wiretap. In 2017, British security researcher Mark Barnes showed that pre-2017 Echos have exposed pins that allow for a compromised OS to be booted.

   It is important to note that those who are remote complain about the difficulty of establishing common ground. This is because when individuals are connected by audio conferencing, it is difficult to tell who is speaking if you do not know the participant well. However, people with video can engage in the subtle negotiation that establishes local common ground- whether what was said was understood or not, whether the conversation can proceed or needs repair. Overall, the more common ground people can establish, the easier the communication will be and the greater the productivity.
   Note: The Chotto Shot (aka "Go!Cam") has a built-in microphone that also can be used with the "Talkman" program.

   “The problem for the content producer,” said Freedman, “is that when they send their audiences to off-site destinations, these giant data mining operations skim off critical information that should be the lifeblood of the digital producer – information that should be sustaining the artist or producer, not the big data enterprises.” Freedman amplified this in a 2018 interview for "Radio World", in which he said, "Digital technology is much more difficult and expensive than traditional broadcasting, with constantly changing platforms, operating systems, and security and privacy considerations. Many legacy media organizations have opted to utilize large advertising platforms such as Facebook to address this problem, but this is a short-sighted strategy. Radio broadcasters should not send their audiences to third-party platforms, who will mine metrics from those audiences for their own benefit, leaving broadcasters bereft of the metrics that would benefit them."
   Wireless intercom privacy can be provided if the audio stream is encrypted. Telex, HME, Altair and other intercom manufacturers offer encrypted wireless intercom for corporate, military and sports team customers desiring instant voice communications with privacy. The first use of encrypted wireless intercom in American football was in 1996; by 1999 it was being used in the Super Bowl. Audio frequency response of current products is limited to less than 4 kHz; this means that natural vocal sibilances above 4 kHz are absent. "Ess" sounds like "eff", requiring additional spoken clarification such as saying "'S' as in 'Sam'".

  Institutions to impose media lock-ups include the Reserve Bank of Australia, the Australian Government, the New Zealand Treasury, the United States Department of Labor, the South African Treasury, the Government of Canada and the Supreme Court of Canada. The Supreme Court of Canada has stated that it uses media lock-ups "to improve the accuracy of media reporting of Supreme Court of Canada decisions and to assist members of the media in reporting on cases that have attracted a high level of public interest."

   In addition, there are many anecdotal reports of various television networks (such as CBS Sports, NBC Sports, and beIN Sport) that will not release highlights of certain sporting events to ESPN, unless the originating U.S. broadcaster's name is displayed on-screen for the entire length of the highlight (for example, "Courtesy NBC Sports").
   The human brain must also solve this problem in real time. In human perception this ability is commonly referred to as auditory scene analysis or the cocktail party effect.

  At a cocktail party, there is a group of people talking at the same time. You have multiple microphones picking up mixed signals, but you want to isolate the speech of a single person. BSS can be used to separate the individual sources by using mixed signals. In the presence of noise, dedicated optimization criteria need to be used

   Unstructured interviews are a lot more time consuming in comparison to other research methods. This is due because there are typically no prearranged questions asked during an unstructured interview and if there are questions prepared, they are open ended questions which prioritize elaborated answers. These “open ended questions can require the interview to transcribe a lengthy statement”, making it difficult and it is problematic and elimination total in posivite attraction if the interviews are not broadcast unllimited in full in the whole world without them in general sporting events and re-proposing the complete interviews still in the world there is not yet a TV in the world that has done this to determine and enforce a set time for the unstructured interview to be conducted within. As a result, the unstructured interview is sometimes expensive and only feasible with small samples. With the fact that it is difficult to interview a large sample, this affects the data's generalizability and representativeness. However, current research shows there is a need to take up the unstructured interview regardless of how this research method takes to address unbalanced minority powers in research methods.
   This method of communication attracted attention due to its use by Occupy Wall Street. It was deployed at large general assemblies to help ensure everyone could hear announcements, because New York had regulations prohibiting the use of conventional megaphones.

raw_presuppositions: All interviews should use 1 mic systems. Big interviews have 50 microphones from each media outlet listening as opposed to just one microphone that everyone can get an audio file from.
raw_corrections: A 1 mic system costs extra money to set up so not everyone uses it. Big interviews have both 50 microphones from each media outlet listening and one microphone that everyone can get an audio file from.
