Edison works to improve Bell's telephone
There were quite a few ways that Edison thought the telephone could be improved. In Bell’s telephone, it was only the vibrations made by the human voice that were turned into electric currents and could be heard on the other line. Because of the sounds were very faint, and even fainter over long distances. Edison chose something different; on his machine, the voice made a valve open or close, and this made a better current than the one before. -

Edison Introduces inexpensive Phonograph
Edison introduced his smallest and lowest cost phonograph to compete with the falling prices, the Gem. This machine cost 10 dollars and could only play records, whereas his earlier models either came with a recording device or one could be purchased for them. A very basic version of the Gramophone came out shortly after the Gem selling for 3 dollars. It was called the Toy. -

Pre-20's: Early Recordings
"At the beginning of the twentieth century, recordings were all made "direct to disc." The storage/playback media were either wax xylinders or shellac disks that were cut live, one at a time. These discs were then played back on one form or another of phonograph (predecessors to the "modern" turntable.)" -

Development of Condenser Microphone
he first high quality, wide range
condenser microphone was developed by E. E. Wente at Bell
Labs as a measurement standard. In order to
satisfy the high-quality microphone requirements of the rapidly
growing radio broadcast and recording industries, Western
Electric introduced the 394 condenser microphone;
subsequently RCA came out with the 4AA condenser
mic. Mic History Resource -

Start of Magnetic Tape Recording
The late 1940s was the start of Magnetic Tape Recording in the US. It initially was only used as a safety backup to direct-to-disc recording and was also the standard for prerecorded radio broadcast. -

MP3 Compression Begins...
MPEG 2 Audio Layer III, or MP3 is a patented encoding format for digital audio which uses a form of lossy data compression that works by reducing accuracy of certain parts of sound that are considered to be beyond the auditory resolution ability of most people. This method is commonly referred to as perceptual coding. It uses psychoacoustic models to discard or reduce precision of components less audible to human hearing, and then records the remaining information in an efficient manner. -
Max Matthews Dies at 84 (inventor of MUSIC software)
Mr. Mathews wrote the first program to make it possible for a computer to synthesize sound and play it back. He also developed several generations of computer-music software and electronic instruments and devices. He was an engineer at Bell Laboratories in Murray Hill, N.J., in 1957 when he wrote the first version of Music, a program that allowed an IBM 704 mainframe computer to play a 17-second composition of his own devising.
