...uot; object and play it back. I`m willing to add the encode\decode features of Jspeex but I can't make it to work, I`m probably missing somethnig. The code (Part of it) : ----- speexEnc = new SpeexEncoder(); speexEnc.init(0, 5, 8000, 1); //narrrow-band, 5 quallity, 8khz, 1 channel speexEnc.processData(buff, 0, buff.length); // 0 - the offset --- buff is the byte array of the ByteArrayOutputStream (=the voice from the microphone). the exception I get from processData() method is: *"Insufficient float buffer to convert the samples"*, and this leads me to the question. Is it true that t...

...ain" java.io.StreamCorruptedException: More than two sideband layers found I've got a feeling the SpeexDecoder class wants/assumes a certain amount of data when decoding and I'm not meeting that expectation. Is that correct? How much data should I hand to the decoder when I call the processData() method?

R-help, After cogitating for a while, I finally figured out how to define a data.frame column as factor and assign the levels within a function... BUT I still need to pass the data.frame and its name separately. I can't seem to find any other way to pass the name of the data.frame, rather than the data.frame itself. Any suggestions on how to go about it? Is there something like

...eexEncoder.getEncoder().setVbr(vbr); if (vbr_quality > 0) { speexEncoder.getEncoder().setVbrQuality(vbr_quality); } } if (vad) { speexEncoder.getEncoder().setVad(vad); } if (dtx) { speexEncoder.getEncoder().setDtx(dtx); } int pcmPacketSize = 320; speexEncoder.processData(cmbuffer, 0, pcmPacketSize); nbBytes = speexEncoder.getProcessedData(temp, 0); return temp; } public static byte[] decode(byte[] decbuffer) { SpeexDecoder speexDecoder = new SpeexDecoder(); int packetCount = 0; byte[] payload = new byte[65536]; int bodybytes = nbBytes; int...

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 ap...

...the number of channels. -After decoding a speex frame, i'm supposed to get linear pcm at what sample rate? The same as defined on the init? What about the number of bits per sample? -On the speex encoding part, the parameters needed on init are related to the linear pcm frame i should pass to processData and it also indicates what type of speex frame i will get? What kind of pcm data can i use to feed the encoder? Maybe some of the questions don't make much sense, but i can't get much info on the subject.

...to speex, so i can then publish it to a flash client. On rtmp spec is said that is used network byte order, so in a speex frame consisted in more than 1 byte, i guess i have to send it in big endian order. By the source code of jspeex i see that when i pass pcm data as a parameter to SpeexEncoder.processData they use it as little endian and convert it to a float[] and only then the data is encoded to a byte[] of speex samples. I'm only getting noise on the flash client side, and i though it could be an endianess problem, doesn anyone have any suggetion? I'm recording the pcm16bit data to a ra...

Hi, I would like to turn some of our simulation codes out to pasture and string some of them together by draping them in web services. I''m looking for a RESTful Camping tutorial to get started ... pointers appreciated.
