The MP3 revolution

The Internet is changing the music industry

“…RIAA is currently looking for more secure and controllable alternatives to MP3. This has brought forth such standards as a2b, Liquid Audio, Beatnik, and Microsoft Media Technology [4].…”

“…This MP3 movement sparked worry in the music industry, where key players (the retailers, record labels, and artists) were concerned about losing money [4]. Although some have attempted to alleviate this concern by showing an increase in CD sales from 1999 to 2000 [5], RIAA has attempted to shutdown as many illegal MP3 distribution Web sites as possible with legal action.…”

“…Increasing availability of broadband access and reducing costs of hard disks allow downloading and storing of songs in MP3 economically attractive. Because it is operable across many technology platforms and has no security or copyright features, MP3 is immensely popular [4].…”

Estimation of the Fundamental Frequency of the Speech Signal Compressed by MP3 Algorithm

“…Such compression ratio enables archiving a digitalized audio signal as well as transferring it by multimedia systems. Accordingly, MP3 became especially popular in internet applications (Hacker, 2000;McCandless, 1999). MP3 is a shortened name for coding algorithm derived from the standard MPEG-1, Layer III, developed by the German Technology Group.…”

“…Technically, MPEG-1 Layer III and MPEG-2 Layer III are declared as MP3 standard. MPEG-1 Layer III is used for 32 kHz, 44.1 kHz, and 48 kHz of sampling frequency, while MPEG-2 Layer III is used for 16 kHz, 22.05 kHz, and 24 kHz of sampling frequency. The standard broadening with a sign MPEG 2.5 is used for 8 kHz and 11 kHz (Hacker, 2000).…”
