The progression of recording equipment over the years has come a long way. In this paper I will cover the progress in its entirety. From the beginning to the current ways that we record music and everyday sounds. There is discrepancies on the topic as to who had the first recording device.

The real growth in emerging technologies began in 1998 with the evolution of the MP3 player. This allowed for a new type of audio-compression that was at the time, a revolutionary means for listening to music. What the creators of MP3 files and music industry experts didn’t know was that this technology that they thought would help them, would actually hurt them in the long run. By developing a type of music file that is so compressed it takes up less space yet maintains the integrity of the audio quality, music personnel predicted that this technology would make it much easier to distribute and enjoy music across many outlets (computers, iPods, MP3 players, etc.). But this creation actually led to the development of infamous online file sharing

MP3 is an audio format that allows users to compress and send music files easily over the Internet. The major problem with this music sharing is that most of the files are pirated, which has caused a stir in the music industry. Music companies and music artists have been complaining about how their music is being stolen and therefore lowering their album sales. The major blame has been put on Napster and other file sharing software available on the Internet.

The development of relatively inexpensive reproduction of music via a succession of formats including vinyl records, compact cassettes, compact discs (introduced in 1983) and, by the mid-1990s, digital audio recordings, and the transmission or broadcast of audio recordings of music performances on radio, of video recordings or live performances on television, and by the 1990s, of audio and video recordings via the Internet, using file sharing of digital audio recordings, gave individuals from a wide range of socioeconomic classes access to a diverse selection of high-quality music performances by artists from around the world.[citation needed] The introduction of multitrack recording in 1955 and the use of mixing had a major influence on pop and rock music, because it enabled record producers to mix and overdub many layers of instrument tracks and vocals, creating new sounds that would not be possible in a live performance.[1] The development of sound recording and audio engineering technologies and the ability to edit these recordings gave rise to new subgenres of classical music, including the Musique concrète (1949) and acousmatic[2](1955) schools of electronic composition. In the 1970s, African-American hip hop musicians began to use the record

Audio and video has been used since 1850’s. Over the past years look at the first Star wars to now the last star wars and the difference between them of the quality, have we really came that far in technology? Has dated back to the first phonogram to mp3 players. First invention was from thomas edison by creating the very first phonogram. This paper is over the advancement of audio and video since the beginning to modern day.

Alan Blumlein was frustrated when he thought about how the sound from a character on screen could only be heard from a speaker at the other side of the room. Alan invented the audio stereo system in 1931 to enhance the sound in a room. Alan Blumlein developed binaural sound (now known as stereo sound) at the Central Research laboratories at the EMI site in Hayes. ("History of recorded music timeline", 2014).

The late expansion of mp3 and other computerized configurations has permitted organizations like book recordings downloaded to distribute the books on the web,

It wasn’t until the 1900’s, however, that the current way of storing and playing back music – with digital audio – became a thing (Millard 1995). As far as digital audio is concerned, the first method of digitally representing analog vocal or audio signals was developed all the way back in 1937. Pulse-code modulation, as it was called, pioneered digital audio recording that is used to this day (Reeves 1942; Black and Edson 1947). The way it works is like this: a recording of an analog signal (such as the auditory waveforms produced by a phonautograph or gramophone) can be sampled by a computer algorithm; the algorithm assigns arbitrary binary numbers (binary meaning zeroes and ones) to each sample measurement of the analog waveform and collects them all as a function of time. This process of sampling, called digital modulation, has two crucial parameters: sampling rate, or how many samples of the audio waveform are taken per second, and bit depth, or quantity of possible digital values (Techopedia 2016). To make this easier to understand, consider the following graph (“File:Pcm.svg,” Wikimedia

Description of Assignment: To figure out application of waveform coding techniques for digital audio transmission and digital audio recording.

Although it is a great way to discover and release music unfortunately the quality of the audio files are generally very poor. Also with the loudness war still on the rise has meant the quality of most MP3s have not gotten better. The loudness war has removed having a desirable dynamic range from modern music with most Internet releases sounding muffled.

For centuries man had dreamed of capturing the sounds and music of his environment by means of music recordings. The road to successful music recording had not been smooth until the derivation of the music recording industry.

Reproduction of sound has come a long way, dating all the way back to 1855 where French inventor Édouard-Léon Scott de Martinville invented the phonautograph. Even though the phonautograph was not capable of doing a playback of what was recorded, it set the path for sound recording. (Crane, 2015)

The birth of the mp3 began with the research of Eberhard Zwicker in psychoacoustics. In researching items like sound pressure and integrity, he turned the concepts into mathematical logarithms like “L=20Log(p/p₀)dB” (Zwicker). Over this time, Zwicker found that the human ear was an adaptive organ which, by natural selection, served two purposes: to hear and interpret language and provide an early warning system against enormous carnivorous cats, and it was no better than it had to be to serve those two purposes (Witt). Around the same time as this research, the compact disc (CD) hit the market in 1982, claiming “perfect sound forever”, being celebrated as one of the most important engineering achievements in

In 2001, the IPod was born and it swept the music industry by storm. They had invented the new way to buy store and play music. The new way to digitally create, share, store, and play music was in the format of MP3. This format makes it very easy to store the music and play it back without any loss of the musical content. MP3 stands for MP is short for the Motion Pictures Experts Group (MPEG) and the 3 is for the layer that the music is written to.
