Porting Vorbis lib on Ti DSP ? How to ?
Hello All, I would be very interested to have your ideas to port the vorbis lib ( part of lib at least) on a DSP TMS320C5409 (running @ 90Mhz). I have reviewed messages and URLs related to: - 'ivdev' Integerized Vorbis Project - Ogg-on-a-Chip Project This is very interesting. In my case I think the best approach would be , in order to shorten porting work & time, to recompile the

How Can I Get involved in Speex Fixed-Point Development?
Hi, My name is Jean Quirion and I am a DSP engineer. Currently I am working on a project where it is desired to implement a VoIP solution over a GSM GPRS link. I would like to use Speex as the vocoder for this application. This application would require the Speex encoder/decoder and possibly the pre-processor to run on a low power fixed-point DSP such as a TI C55x. Thus, I am interested in

fixed-point OGG Vorbis encoder
Hello, Iam interesting in transcoding the algorithm of OGG VORBIs in fixed point because I have to implemente this encoder in a fixed point DSP. Does the source code of ogg vorbis encoder exist in fixed point or is there people that work on this or anything else?

OPUS in embedded platform
Hello, I am interested in porting OPUS to an embedded platform. The idea is that the encoder and decoder will run on different processors. In order to choose the proper platform, I need an estimate of the resources which are needed for OPUS. I read the following in the OPUS wiki: "The Opus code base is written in C89 and should run on the vast majority of recent (and not so recent) CPUs.

Fixed vs. Floating Point primer. was: Implementing Vorbis in hard ware
Let me chime in with a few facts regarding DSPs. It may be review to anyone who has programmed DSPs, but some may find it informative. Fixed-Point vs. Floating Point DSP chips Floating Point DSPs make the best/easiest compiler targets. Most of the standard operations present in ANSI C translate fairly well into floating point DSP assembly. This reduces the need for assembly

Fixed point version.
I have read a few messages about a fixed point version and I have some questions. 1. Will just the decoder be available in a fixed point version. 2. If the encoder is available will it work on a 400 mhz XScale "Strongarm" 3. Will it work on a dsp? if so how fast of one will I need. 4. Any chance of a FPGA version? I really need to be able to encode in real time or very close to it in

mixed case usernames
I haven't found anything about this in the FAQ's... Despite having a translation from an all uppercase (or all lowercase) to the mixed case Unix username in the username map, the samba server (1.9.18p1) does not allow browsing from a Win95 client. If I change the username to all lowercase on the Unix server, then browsing works fine. Have I missed something? -- Phil Etheridge

transfering decoder state
Hi Jean Marc and everyone else :-) I am a bit of an alien here, my expertise is not at all in DSP: I am in network games and recently I started to work in a team dedicated to audio for games. Our prefered codec is speex, mainly for its quality/bandwidth ratio and of course because it is open source. You DSP guys would probably curse us if you saw what kind of ugly things we do to compressed

More mdct questions
Sorry for starting another topic, this is actually a reply to Segher's post on Sun Oct 22 on the 'mdct question' topic. I wasn't subscribed properly and so I didn't get email confirmation and thus can't add to that thread. So Segher, if the equation is indeed what you say it is, then replacing mdct_backward with this version should work, but it doesn't. Am I applying

How many MIPS for Vorbis Decoder?
Hello, I may be stupid, but I cannot find any data on how "expensive" the Vorbis Decoder is. Looking for an embedded solution I am interested in how many "MIPS" you need to decode a MONO audio stream at reasonable quality (44 kHz, approx. 100 kbps?) Can it be done in a microcontroller, or do I need ultra-expensive DSPs to do it? Thanks for hints Jens --- >8 ---- List

hardware ogg vorbis decoder
As it seems that the vorbis decoder is now stable with respect to format/features, would it be time to start thinking about a hardware implementation? I would be interested in pursuing this if some there is consensus on requirements. If there is some enthusiasm for it then a module could be set up on the opencores site for a gate-array decoder. cya, Andrew... --- >8 ---- List
