Any integer lossless encoder to fit "iRockbox"?, A suitable lossless encoder for Rockbox?

Hello,
As some may know the Rockbox iRiverport for iHP1xx is on his way thanks to LinusM releasing his precious "bootloader"...

Actually the team is concentrating his work on the AUDIO part... The great priority of course is decoding (especially MP3 even if a lot of audio codecs are in the TODOlist!)

Anyway the team have made some searchs for encoding part and they complaining they don't find much things that seems suitable for the iRiverport since they need INTEGER encoders that won't overdrive the iHP processor...

So i've asked on the HA "rockbox iRiverport" thread for LOSSY integer encoder with Open-source license of course (check HERE)...

As there is a lossless section i make this thread to ask the same thing but for an interger lossless open source encoder!

I will be very kind of you to put all information you know about such an encoder! smile.gif
Thanks,

Tanguy

(minor correction, lossless encoders can use floating point math. e.g. libFLAC uses floating point in the LPC analysis stage.)

the latest release of libFLAC has a compiler define (FLAC__INTEGER_ONLY_LIBRARY) that builds the whole library (decoder, encoder, etc.) with integer only.

Hi,
Thanks for these correction... in fact seems that for now the Rbx team get info directly here in the HA threads... It's the best way... So there is no need for me to report them any new information.. smile.gif I guess they will subscribe to HA board when they will encounter big issue and would contact any precise member or ask something to community...

BTW I'm very thankfull to every HA people... smile.gif
Best regards,
Tanguy

PS: I'll check the Rbx HA thread to add any new infomation if it appears necessary... in fac I'm gonna add something NOW (latest progress) so stay tuned... smile.gif
