similar to: Speex play back

I am a Java developer. I represent a small company writing a audio archiving application in Java using SPEEX files on Windows 2000/XP. We have been using the software found at the main SPEEX site and looking for API's we can use there. We are looking for a Java based SPEEX API that allows us the following playback functionality: - Open the SPEEX file from local file system or via a http

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

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

Thanks for your reply. I am using JSpeex so it is not possible to use the libs you mention. I looked a little at the source in http://jspeex.sourceforge.net but cant see where the length can be stored. Unfortunately, that project does not seem to be maintained - no replies to queries posted on the forums. Does anyone know how to store the length of a JSpeex clip in the header? thanks, Anil ---

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

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 also support 16kHz (wb) and 32kHz (uwb), but nothing outside of

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 , srcFormat.getSampleRate(), -1, //

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 source works with raw speex audio

Hi all, I have XiphQT installed and have some Ogg theora videos I would like to play in Apple's Keynote presentation software. They play fine in iTunes using XiphQT but don't work in Keynote. I have each video in two formats: (1) in a ".ogg" file, and (2) in a ".mov" file created by opening the ".ogg" file in QuickTime Pro and saving it as a

Hi Ulrich, I've never had any OutOfMEmoryExceptions in my tests, and I think I've been rather thourough, although probably much more thourought testing narrowband than wideband. Having said this, it is very hard to get memory leaks in java, so I am sceptical about that. That memory might not be used optimally is more likely the case. More often then not reducing memory use

Hi Sanjiv, There does indeed appear to be some trouble with the Javasound SPI encoder (the SPI decoder works well). I am working on it, and hope to have a fix soon. In the mean time, you can use the encoder outside of JavaSound, that one works well (see the command line encoder as example code of how to implement it). sincerely Marc Gimpel Head of research Wimba <p>On

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

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 and live a meaningful life to its

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

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

Hi all, I got swfdec compiled and running, however there are a lot of problems running it ! As a test I tried: swfplay http://www.youtube.com/v/lUR6laFLk0A First of all I see: SWFDEC: ERROR: swfdec_codec_gst.c(231): swfdec_gst_decoder_init: failed to create decoder SWFDEC: ERROR: swfdec_codec_audio.c(192): swfdec_audio_decoder_new: no suitable decoder for audio codec 2 SWFDEC: ERROR:

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.Info targetInfo = new DataLine.Info

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.

Is there a document somewhere that describes speex-encoded FLV files? What is a TC message? Thanks. Jozsef Vass wrote: > FLV contains TC messages?
