However, MP3 files do not have the audio quality of a digital recording on compact disk. The files compress the data and loss of quality is the result. A digitally recorded CD from 1985 has better sound quality than the best MP3 of today. The next step will be to create audio files of small enough size that they are portable without losing audio quality.
"(Digital recording) greatly increased sound quality and minimized recording errors."
This isn't an altogether factual statement. Digital recording allowed for a higher signal to noise ratio, but actually was of more limited range than analog tape recording. Also, while digital recording did eliminate some analog recording errors (e.g., timing, pitch, wow & flutter), it introduced a new category of recording errors (e.g., quantization, jitter) that hitherto had not been a factor in recordings.
@ferociousgumby Hey if you want to hear samples of some of the worlds first recorded audio the SmithsonianAmHistory Youtube Channel just uploaded some clips from the late 1800's that have never been heard before now.
'Polysilicon Recording'. This was a conceptual music memory device, proposed in 1981. The ten-year development plan was to create an affordable digital music chip, but that scheme ran out of time 1991. The kind of mass storage digital memory devices required for the task would take a lot longer to develop. Ironically, 1991 was a year in the development period of the MP3. The Free Lossless Audio Codec (FLAC) emerged ten years later. Also ironically, flash memory now fulfils the 1981 plan.
Note: The original 7 inch Berliner discs ran at approx. 60 RPM, not 78. Acoustically recorded disc records ran anywhere from 60 to 140 RPM in the early years. The standard of 78.26 RPM for records was established in 1926 for electronically recorded discs. This was based on further research by Emile Berliner, who established this speed as optimal for all disc type records. There is really no way to summarize recording history is such a small timeline.
@stratocat9999 thanks for that very interesting extra information.never knew the exact stats of 78,and can't imagine a record playing at 140 rpm! that's the kind of thing i used to do as a kid and send the stylus flying off the LP,i suppose we all went through our fair share of mishandled players in the beginning,at least all the real record nuts.
@dimebagdave77 LOL, yeah I think we all did that once or twice. :) I think the Pathe 14 inch disc ran at 140 RPM. I know they were inside start, and vertically cut. There are few videos posted on YouTube of discs running at 120 to 130 RPM. Victor had an experimental line of 14 inch discs that ran at 60 RPM, and there is an example of one of these floating around YouTube too. From 1879 thru the mid 1920 there were a lot of variations on size, speed, and groove modulation.
Good job here. Note I have in my collection 33 rpm Columbia discs made exclusively for WW2 allied radio stations. I also heard about a record found in France with a Scott de Martinville recording, so it is the first record ever known.
Magnetic tape (using a paper substrate) started in 1928, and was commercially available in 1935.
Wire recorders were in use from the 1890s till the 1960s (largely for dictation). The BBC recorded programs in 1932 using metal tape (25 kilos per half hour). The improvement during the war was in quality, due to AC Biassing.
8 Track "Cartridges" were better quality (double the tape speed) than the "Compact Cassettes" which superseded them due to smaller size and ability to fast forward and rewind
Some clarification. Edison introduced the "LP" (long Playing) disc in 1927. There were the 12" 40-minute discs (20 minutes per side at 78 rpm), and 10" 20-minute discs. They were unique, but proprietary and didn't catch on.
Music always gets people through the hardest of times, slavery, refugees, the poor, the rich it doesn't matter, its a celebration of emotions through communication. @sandhgreen
Actually, as soon as 1949, Columbia tested the first three-speed player, and Admiral made the first commercial three-speed player that very summer. While the MP3 format was invented in 1992, the first portable MP3 player, the Diamond Rio, came out in 1998.
Whats next? Well, USB devices are it. I don't see audio changing much from now on. Of course there are many different formats (mp4, wma, wav, etc) but they all rely on binary code. As far as science goes, this binary code is probably as good as it gets. Binary code is what runs every computer and digital device, and we only improve upon computer technology rather than reinventing it, so audio recording will stay in its form now forever.

This needs examples of each kind of sound recording. It's good info but EXTREMELY DULL! How can you "talk about sound" without demonstrating it?????

Digital is not of inherently better sound quality, but is more stable, and with modern memory size and processing power, is cheaper.
Mp3s Are NOT the digital signal from a CD. They take the already dubious quality of CDs and reduce it considerably further.
What's next ? Probably now the capacity is there, a move back to better quality

cool the first recording was in 1857, but are those recordings ever recovered ????
also was the first digital recording in the early 1970,s?
