The RIAA soon filed a lawsuit alleging that the device abetted illegal copying of music, but Diamond won a legal victory on the shoulders of Sony Corp. The Rio was a big success during the Christmas 1998 season as sales significantly exceeded expectations, spurring interest and investment in digital music.

It was a very basic unit and wasn't user-expandable, though owners could upgrade the memory to 64MB by sending the player back to Eiger Labs with a check for $69.00 plus $7.95 shipping.Īnother early MP3 player was the Rio PMP300 from Diamond Multimedia, introduced in September 1998.

The first handheld portable MP3 player released on the American market was the Eiger Labs F10, a 32MB imported version of the MPMan F10 that appeared in the summer of 1998. It retailed for $599 and was a commercial failure. It consisted of a 3GB IBM 2.5' hard drive that was housed in a trunk-mounted enclosure connected to the car's radio system. The world's first car audio hard drive-based MP3 player was also released in 1997 by MP32Go and was called the MP32Go Player. In 1997, the world's first MP3 player, the MPMan F10, was developed by a South Korean company SaeHan Information Systems.

It was based on several audio data compression techniques, including the modified discrete cosine transform (MDCT), FFT and psychoacoustic methods. MP3 was introduced as an audio coding standard in 1994. It could store up to an hour of music, but despite getting an award at CES only 25 copies were made. The Listen Up Player was released in 1996 by Audio Highway. The project was controlled by an expert in mathematics and electronics, Karlheinz Brandenburg. In 1987 a German research institute, part of the Fraunhofer-Gesellschaft, started the research program for coding music with the high quality and low bit-rate sampling at its institute. However, in 1988 Kramer's failure to raise the £60,000 required to renew the patent meant it entering the public domain, but he still owns the designs. Later Kramer set up a company to promote the IXI and five working prototypes were produced with 16-bit sampling at 44.1 kilohertz with the pre-production prototype being unveiled at the APRS Audio/Visual trade exhibition in October 1986. Plans were made for a 10-minute stereo memory card and the system was at one time fitted with a hard drive which would have enabled over an hour of recorded digital music.

The player was as big as a credit card and had a small LCD screen, navigation and volume buttons and would have held at least 8MB of data in a solid-state bubble memory chip with a capacity of 3½ minutes' worth of audio. UK patent 2115996 was issued in 1985, and U.S. In 1981, Kane Kramer filed for a UK patent for the IXI, the first Digital Audio Player.
