MP3-Codierungs-Chips? [geschlossen]

Ich suche nach MP3-Codierungs-Chips. Alles, was ich gefunden habe, ist dieser MAS3587f, der ungefähr 4 USD kostet. Gibt es noch andere billige Chips?

Das sieht für mich gut aus - was ist daran falsch? Vergessen Sie nicht, dass der MP3-Standard patentrechtlich geschützt ist. Daher müssen Gebühren in jeden Standard übernommen werden.

Now, it's patent free: "The basic MP3 decoding and encoding technology is patent-free in the European Union, all patents having expired there by 2012 at the latest. In the United States, the technology became substantially patent-free on 16 April 2017 (see below). The majority of MP3 patents expired in the US between 2007 and 2015" , source en.wikipedia.org/wiki/MP3#Licensing_and_patent_issues

(1) BU94702 made by Rohm. It isn't cheap, but it is [was?] one of the few options for codec ASIC with MP3 encoding. (2) Here's a similar request about MP3 codec ICs on the TI support forum [TI has got a fair few codecs which digitize audio, but don't do MP3]. TI's suggestion is to use one of their DSPs instead of an ASIC. (3) MP3 library for PIC32.

Another one is the VS1063 from the Finnish company VLSI Solution (http://www.vlsi.fi), although $4 seems like a great price -- the VS1063 is $25 each for 1-99, only goes down to $4.80 each for 1000+ pieces.

Indeed, $4 is much better than $25. :-)
