similar to: jspeex distortion playback issue

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

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, 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

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?

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).

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

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

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, I downloaded Ulrich's TestClient and have not been able to connect to the default server. I will try to modify and get to work locally(local echo). I wanted to test my SpeexDecoder as no matter what I try I alwasy get an java.io.StreamCorruptedException: Invalid sideband mode encountered. (2nd sideband): 7 Please note that the Invalid sideband modes differ per file but the end result

Hi., I am trying to implement speex. Currently i am capturIng sound and encoding it using Pcm2SpeexAudioInputStream. I am feeding bytes from this stream to Speex2PcmAudioInputStream and trying to read decoded bytes. But here the decoder is giving me an error "saying sideband error" and values after it vary with every message. I donno the reason for this, but I guess it is because

hai i hope you are well i would like to know whether jspeex can be used in android phone. i want to convert convert the speach signal to .spx signal in android Is it possible to get a working java example? thanks for spending your time reading this mail :) -- Thank you With Respect --evan hackborn-- -------------- next part -------------- An HTML attachment was scrubbed...

Hi, It would appear the the 'pcm2speex.read(frame, 0, frame.length)' is blocking which means that it is waiting for data from the underlying inputstream (i.e.AudioInputStream(t.input)). If it could read sufficient data it would transcode it. If it recieved an EOF, it should do some zero padding and then transcode it. Are you sure that you are receiving data from the underlying

Hi I am getting lost ogg sync exception when I tried to decompress a speex stream. I am using the following program for both compressing as well as decompressing.
