Lo Digital: MP3 y streaming

The format that closed the golden era: from the Fraunhofer laboratories to Napster

Born in the laboratories of the Fraunhofer Institute, the MP3 made music fit into a file; with Napster (1999) an entire collection fit onto the internet — right at the border where the Archive's period ends (1967–1999). Streaming is its descendant and our present.

The MP3: music made file

The MP3 (MPEG-1 Audio Layer III) is the compression format that turned music into a lightweight computer file: taking advantage of the limits of human hearing, it discards what is not perceived and reduces a song to a fraction of its original size without ruining the listening. It was developed mainly at the Fraunhofer Institute in Germany, under the leadership of engineer Karlheinz Brandenburg, whose doctoral thesis (1989) on perceptual audio coding laid the foundations of the format.

Unlike vinyl, the cassette or the CD, the MP3 is not an object: it is the first time in the history of this collection that the format stops weighing anything, stops filling crates and stops being sold in stores. That dematerialization — imperceptible at first, seismic in the end — is what would close the era of the physical formats that structured the whole of miniteca culture.

Milestones of the format

· The 80s — research into perceptual audio coding in Erlangen (Germany); in 1989 Karlheinz Brandenburg presents the doctoral thesis that underpins the future MP3.
· April 1993 — the MPEG standard that includes audio Layer III, the technical basis of the format, is adopted.
· July 14, 1995 — the Fraunhofer team officially adopts the “.mp3” extension for its files (until then they used “.bit”): the name the world will learn is born.
· June 1, 1999 — Shawn Fanning launches Napster, the MP3 file-sharing service: within a few months 4 million songs are in circulation and in less than a year more than 20 million people are using it. Recorded music changes scale — and rules — forever.

1999: the format that closed the period

The MiniTK Archive covers strictly the period 1967–1999, and it is no coincidence that its final border coincides with Napster: the year music stopped being an object marks a natural close for the history of a culture built on objects — acetatos bought in line, crates hauled by hand, jingle tapes, silver discs in the dual tray. The digital did not kill the party, but it dissolved the material world that sustained it: with an entire collection available on a hard drive, the age of formats in movement — the ones that had to be moved physically — came to an end.

That is why this entry frames the MP3 as “the format that closed the golden era”: it is the last chapter of the Archive's period and, at the same time, the prologue to everything that came afterwards.

Coda: streaming as the present

Streaming is the direct heir of that digital leap: as the collection's original article sums it up, online platforms today “make it possible to reach millions of songs in seconds, closing a circle that joins past and present in one same passion: enjoying music in all its forms.” It is the present from which this Archive looks back — and the reason an online radio station can today give the listener back, in one click, the music that once traveled in crates.

Note on scope

The core of this entry (MP3 and Napster) belongs to the 90s, within the Archive's period; streaming is later than 1999 and is included only as a coda of the present, not as an object of historical documentation. The Archive records no miniteca episodes of its own for the MP3 — reading 1999 as the close of the era of the physical formats is an editorial framing by CMTK, declared as such, not a datum from the magazine.
