frame size for a given quality?
Jeff, It's in the manual: http://www.speex.org/docs/manual/speex-manual/node10.html (table 3 and 4). However, if you're asking this, you're probably trying to do something wrong, or the hard way. You probably shouldn't be taking speex output, and trying to "count bytes". If you are using the API, then you will just get the bits out, and then you'll know how

frame size for a given quality?
Have you tried typing "speex rtp" into google code search? It gives lots of examples of real applications which do exactly that. http://www.google.com/codesearch?as_q=speex+rtp -SteveK On 11/1/10 1:13 PM, "Jeff Ramin" <jeff.ramin at singlewire.com> wrote: > >Thanks again Steve.

frame size for a given quality?
Jeff, RFC-5574 is standards-track: http://tools.ietf.org/html/rfc5574 so, while it's not an approved standard, it's more standardized than a lot of interoperable traffic on the internets these days. The RFC specifies packetization guidelines, which is basically that you put one or more frames in a packet, and then pad the rest with 0 bits until you have a while number of octets.

debugging static
I have a couple apps running on my machine; one takes a PCM audio stream, converts it to Speex, and sends it over the network using RTP. The other receives the RTP packets, and then converts the Speex data back to PCM. The PCM is then played out the audio system. I'm currently ending up w/ static. Anybody have any pointers as to how to debug the situation? Thanks. -- Jeff Ramin Software

herky-jerky audio
Just an update, and a follow-up question: I'm making progress on this issue, and will likely have something working very soon, now that I understand how the jspeex transcoding classes work. Unfortunately, I will need to make a couple small changes to the jspeex source code. My question is - is anybody using jspeex for streaming speex-encoded audio? It works great for static audio, but seems

Yes, I have made that search, but I'm restricted to Java. On 11/01/2010 12:21 PM, Steve Kann wrote: > Have you tried typing "speex rtp" into google code search?

frame size for a given quality?
Thanks again Steve. I'll search for the term you mention below. What I really want is to take the output of the speex encoder and spit it out on the network via RTP. I haven't been able to find a library or code example that does that. On 11/01/2010 12:03 PM, Steve Kann wrote: > Jeff, > > It's in the manual: > >

frame size for a given quality?
Thanks Steve. Is there a document anywhere that shows how many bytes/bits of data are produced by the speex encoding process for a given amount of time sampling rate and quality setting?

transcoding G.711 (u-law) to Speex
Hi folks. The jspeex library has classes for converting speex to pcm and vice-versa. I also have other code that converts from G.711 to pcm (and vice-versa). I want to transcode G.711 to speex, using an input stream. Can I accomplish this in one step, or must I go G.711 -> PCM -> Speex? If possible in one step, is there some example code I could look at for reference? Thanks! -- Jeff

jspeex question
FLV contains TC messages? TC message payload contains a format byte and speex frames (up to eight). In the format byte 0xb0 indicates speex. Speex is always 16 kHz, 16 bit, mono.

jspeex question
The link is http://www.adobe.com/devnet/rtmp/. TC Message stands for TinCan message. It is 11 bytes long, first byte is message type, three bytes of payload length four bytes of timestamp and three bytes of stream ID. The first byte of the payload for audio message is the format byte and the rest of the byte is the payload. Jozsef ----- Original Message ---- From: Jeff Ramin <jeff.ramin

Is Jspeex still being worked on? Is there somewhere I can send the code changes I've made to facilitate smooth streaming?

jspeex question
Thanks for the help folks, but I got this working a couple hours ago. =) I'm quite please after struggling with it for a few days. I just needed to take each audio tag from the FLV file and feed the contents of the tag (except for the first byte) to the jspeex decoder and write the results to a file. Jozsef - it is possible to specify 8KHz in the flash client and decode it as such. Speex
