From: Paul Suade <paul.suade_at_laposte.net>
Date: Thu, 29 Aug 2002 13:30:16 +0200 There is a mas plugin but it is not free. So better to forget it. The only solution is the ability to encode wav or pcm in mp3 in real-time the fatest way (is there any possibility to encode uncompressed mp3 ?). The trouble is : can SH1 be able to do such a job ? ----- Original Message ----- From: "Steve Lhomme" <steve.lhomme_at_free.fr> To: <rockbox_at_cool.haxx.se> Sent: Thursday, August 29, 2002 1:10 PM Subject: Re: PCM files & WAV-MP3 > Nielsen Linus (ext) wrote: > > Please, please, please read the FAQ: http://rockbox.haxx.se/docs/faq.html > > I did already. > Search for "PCM" : none > Search for "WAV" : none > > only : > "18 I don't see you mentioning other file types on your list of ideas. > What about supporting those? > > Pessimist's Answer: At the current time we belive this is not very > likely The Micronas chip (MAS3507) decoder in the archos does not > natively support decoding and there is very little program space in the > player to implement it ourselves.
