The earliest sound devices started with Thomas Edison’s creation, the phonograph, he was working in his lab playing Mary’s Little Lamb from a piece of tinfoil wrapped around a spinning cylinder that could be scratched by a stylus or pen to make sound was played. The first device to actually record sound waves was the phonautograph although it did not have the capabilities to playback what was recorded, it could only be viewed for visual study. The gramophone was a machine that used flat discs with grooves and bumps to produce sound by turning a hand crank for a few second.
Magnetic tape was used to record sound and audio through electricity and was played back using the magnetophon. [The way you recorded audio onto the magnetic tape was by using a process called electric microphone recording process]. It increased the flexibility of the process and the sound quality. The magnetophon was used for radio broadcasting during WWII. The creation of the three track recorders was really popular in the 1950s to the 1960s and was used to record stereo backing tracks, the third track was used for vocals such as, singing and talking. Next was the four track recorders and became a necessity for all audio studios in the 1960s. Two of these were generally used to transfer multiple tracks to another location.
The invention of digital recording was a huge breakthrough for the audio producing community, invented in the 1970s using pulse-code modulation also known as PCM. PCM represents samples analog signals at constant intervals that are close to the nearest value within range of digital steps. The alesis digital audio tape recorders were invented in the 1991, a machine that used VHS video tape to record 8-tracks of audio. Hard disc recorders were a major jump in technology and introduced the MP3 audio file format that is still used today. Music tech and distribution has progressed at a tremendous rate. With introduction of the HDR music and audio files, can be stored and transferred over to the computer with ease, plus there isn’t any need for tape.

There are many ways that podcasts affect people’s lives, for example someone could listen to a podcast to learn information for something they’re interested in. If someone is going to college to be an astronomer, they could listen to a podcast explaining the stars and space, or they could serve as a news program, if someone doesn’t have access to the news they could listen to a daily podcasts about the news for their area. Or podcasts could just simply be for entertainment. Or if someone has a hobby they want to get more experience in they could listen to a podcast. Podcasts can also help people make friends because if there are two people that like the same podcast they may talk about it and find other thing they have in common.
But some people may not want to listen to a podcast or have no interest in it. It’s really all up to opinion and your views. Some people may not have the technology to listen to podcasts.
