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 to fall short when processing audio on the fly in a stream. Thanks...

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. Cheers, Jo Yew Everyone should have a big dream a...

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 definitely does not need to be 16KHz. Jozsef Vass wrote: > The link is http://www.adobe.com/devnet/rtmp/.

This is best answered by the jspeex folks, as it is the interfacing code that you are having problems with. That being said, it looks like, just as it says, you have asked for a conversion it cannot do -- you want it to convert PCM data to speex data at 44.1kHz sample rate -- speex only supports 8kHz in standard operation. It can al...

hello i use the java lib jspeex from http://jspeex.sourceforge.net/ now i use this java code to encode to speex audioInputStream = AudioSystem.getAudioInputStream(srcFile); AudioFormat srcFormat = audioInputStream.getFormat(); AudioFormat targetFormat = new AudioFormat(SpeexEncoding.SPEEX_VBR8 ,...

I'm new to Speex and I'm trying to compress audio using JSpeex in a servlet then play it back on the iPhone. I've managed to get Speex to compile on the iPhone by copying the speex and libspeex folders into XCode. I've read the sample code and the PDF documentation and I have a rough idea how to decode a raw stream. (I'm assuming the sampledec sour...

I am not sure if this is right place to ask for help on jspeex or can some one suggest. I have tried on jspeex sourceforge.net page. I am trying to use Pcm2SpeexAudioInputStream by creating it from tdl which received pcm_signed audio data as follows: AudioFormat format = new AudioFormat (AudioFormat.Encoding.PCM_SIGNED, 8000, 16, 1, 2, 8000, true); DataLine.I...

I'm having difficulty encoding audio using the JSpeex Speex Encoder. My program throws an "Unsupported conversion" exception and I can't figure out why. I've read the related posts and I think I'm doing everything that was recommended. I'm working on Linux, by the way. Any help would be greatly appreciated. Richard Here...

I read the question: http://stackoverflow.com/questions/3403152/acoustic-echo-cancellation-in-java/3403198 But my problem is that my project is using Encoding and decoding mechanism using JSpeex and I am not sure whether I can integrate the above java code with my project. So can someone tell me how can I implement Acoustic Echo Cancellation (AEC) using JSpeex(Java Port of Speex). -------------- next part -------------- An HTML attachment was scrubbed...

Hi all, I'm having a playback issue I can't eliminate. I'm encoding 16khz mono WAV files (voiceover recordings) to speex using a quality setting of 4. In any standalone speex player e.g. winamp or using speex frontend etc. the files play fine, but in a jspeex environment there's a subtle high pitched beeping type distortion, mostly on the transients. The sound is similar to digital sync/clock problems, when connecting digital audio interfaces. I've tried many process prior to encoding to eradicate the issue, but nothing works. However, i...
