converting unsigned short sample to signed short sample
.... the idea is clear for me that i should scale down each unsigned sample by 0x8000 for becoming signed. I hope that will work correctly as input raw samples to Speex codec. do you think so ?

using unsigned short instead of short for input frame
...ted help. i found casting fromunsigned short to short gives different value: unsigned short FFFF=65535 where short FFFF= -1. however, can i configure speex codec (specifically speex_encode_int function) to take input of type unsigned short instead of short so that i avoid casting errors ?

converting unsigned short sample to signed short sample
...y mid point, I mean if you have a pure tone (i.e., a sine wave) that has unsigned range 0 to 0xffff, then the mid point is 0x8000. The mid point should be translated to zero. If your samples are represented some other way, you have to tell us. -- Stephen Checkoway On Mar 13, 2012, at 23:28, Mashal al-shboul <shboul8989 at yahoo.com> wrote: > Thanks a lot for replying, > The question now is , after subtracting 32767 from each unsigned sample, will the new signed samples represent the same original voice ? > For explanation, assume "Hi" is said in 8000 unsigned...

Buffer flushing
Short question: is there way to tell EM to actually send data after send_data call? I''m building a file transferring app. I send Mashal.dump''ed metadata first, and then - the file contents (chunked). I found a silly bug: receive_data() gets marshalled metadata and the first chunk of the file in a single variable. Like that: c1.send_data("meta") c1.send_data("chunk1") c1.send_data("chunk2")...

The decoded voice is just noise and totally different from the original !
Hi all speex developers, ??? I have encoded 10 seconds buffer of Mic voice (raw) using speex on an embedded device, then transmitted it to a PC where i decoded the voice,in a way similar to the sampleenc.c and sampledec.c on website, ?BUT my problem is that the decoded voice is totally different from the original,what i hear is just noise !! what is possible to be the reason ? Any help is

problem: The decoded frame is not as the original one
Hi All, i need your help in determining the problem in the following sample code (taken from speex manual) for fixed point encoding. i tested encoding a 160 sample frame and then decoding it back But The problem is that the decoded frame is totally different from the original frame(see output below).What is the possible reason for this?.thanks for any help #include<stdio.h>

Need For Help about audio data compression
Hi all, I am new to the mailing list , and i need your help. i want to compress audio raw data (PCM) after i have captured them in (sensor) and get them as 16-bit integr samples. that is, when i capture voice for,say, 1 second, i get an array of 8 kilo sample, and I NEED TO COMPRESS THIS SO THAT I GET A SMALLER SIZE BEFORE I TRANSMIT THEM WIRELESSLY. Does Speex allow me to such compression ? Any
