Hi, Vipin, What you're going to want to do here is convert your 8-bit stereo samples into 16-bit mono samples and back again when you're done(*). What you are actually doing here, it sounds like, is feeding 2 8-bit mono samples into Jspeex, which expects 16-bit mono. So, the most-significant-byte is in the right channel, and more or less gets encoded/decoded properly, but the

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

Flash player encodes speex at 16 kHz, mono, 16 bit. Fields in the format byte should be ignored if the format is speex. You can set the quality by Microphone.encodeQuality (default 6). You can also set the number of speex frames per tc message using Microphone.framesPerPacket. Flash player can only decode speex at 16 kHz, so make sure you have the proper sample rate.

hello, i switched to use the encoder.processData() and encoder.getProcessedData() of jspeex. however it looks to me like a memory leak ... memory usage is increasing very fast and there is no visible stop ... after about five minutes java.lang.OutOfMemory occurs. I think it must be the jspeex component, because before i added jspeex to my app usage was constant at about 5mb. is it possible

hello, i have a simple question about speex frame size. i work with jspeex - but i think it's speex generic, the question i have. can i use any frame size i want? or does the size have be in a certain ratio to other numbers? and what does the frame size in the decoder mean? encoded or decoded packet frame size? how much data can i hand to the encoder to encode? if i hand i.e. 400 bytes to

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

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.

Hi, Is real-time possible with the current java-based JSpeex for real-time full duplex voice communication? If yes, can you please also provide some details of the Wintel (Windows on Intel) specifications that you have used to achieve that, and perhaps the JSpeex encoding/decoding specs used? Thanks.

Yes, but this is java. You don't use any threading models and i dont know if you encode from sound card. I also don't

Although this actually pertains to JSpeex, I am asking these questions here because they are general questions and also the JSpeex project does not seem to be supported any more. 1) Can the duration of the clip be stored in it? Page 24 here http://www.speex.org/docs/manual/speex-manual.pdf describes the format, but I could not see where the duration of the clip is stored. 2) Since the Speex

My apologies if this request is a little outside the scope of the normal track of this discussion group. My question is more about the use of speex as a web developer than about the internals of the codec. I searched all over the web for this information, though, and am trying here as a last resort. I am trying to develop a way to offer slide shows with a voice-over. I would like to offer speex

I am having some trouble calculating the duration of my speex files. I am writing a speex player in Java and I am using the JSpeex port of the codec which works but doesn't give me the audio duration which I need to show progress or implement a scrubber. JSpeex appears to be all but dead but I don't see any other option for Java playback. I have tried the method posted here:

I recommended in a bug report that the new mobile platform - Android should use speex and it was accepted. I was wondering if I can use it as a 3rd party library even now. Can someone please tell me how? The JSpeex project has had no activity for almost 3 years and questions are unanswered. the android post is here
