speex_nb_mode declaration problem
Hello all,
I am using the speex APIs in a gnuradio block.
I used the similar code as in the sampleenc.c/sampledec.c which works
perfectly fine.
My compilation does not give any error, but when I run the python test, it
complains that speex_nb_mode is undefined.
I tried to declare it explicitly then it as const SpeexMode *mode = NULL ,
then i get an error that i cannot initialize the const SpeexMode type.
Can someone help me with this problem?
Thanks for your time and attention.
Regards,
Kshama

libspeex.dll
...eased as freeware under the bsd license. We have no commercial intentions
in mind.
One developer start to implement the speex codec to this project.
Unfortunately he has some problems to implement the speex headers.
According to the manual "speex_encoder_init" expect a pointer of
"speex_nb_mode". Sadly, this constant is not exported by the windows dll
(see export table of "libspeex.dll" v1.1.6).
Just as extern const SpeexMode speex_nb_mode; extern const SpeexMode
speex_wb_mode; extern const SpeexMode *speex_mode_list[SPEEX_NB_MODES];
Unfortunately we could not find any f...

encoding time
Good afternoon!
Thank you for your product Speex. We want to use it in
microcontroller AT91SAM7S256 (48 MHz).
We applied the following:
#define FIXED_POINT
#define DISABLE_WIDEBAND
#define DISABLE_HIGHPASS
#define MANUAL_ALLOC
#define OS_SUPPORT_CUSTOM
at
speex_encoder_init(&speex_nb_mode);
speex_decoder_init(&speex_nb_mode);
tmp=2;
speex_encoder_ctl(st, SPEEX_SET_QUALITY, &tmp);
Encoding time for one frame (20 ms) is 46 ms,
and decoding time is 4 ms.
Is it possible to reduce encoding time?
Thank you.
Best regards,

About reducing noise..
Hello,
When I decode a recoded sound encoded by speex, it has too much noise.
The noise is "slightly" reduced if I set the quality to 10. How do I get
rid of this noise? The code is as follows.
For encoding .
state = speex_encoder_init ( &speex_nb_mode );
tmp = 7;
speex_encoder_ctl ( state, SPEEX_SET_MODE, &tmp);
// set quality
tmp = 10;
speex_encoder_ctl ( state, SPEEX_SET_QUALITY, &tmp);
// initialize bits
speex_bits_init(&bits);
while( 1 )
{
// read FRAME_SIZE bytes from buffer
// convert to short

speex headers and borland c++ builder (bcb)
hello,
I try to include the speex header to a bcb project. Speex headers are the
latest
one. My first problem was to use the lib file with bcb. I solved this issue
by
restructing the lib file. The second problem is to access the constant
called
"extern const SpeexMode speex_nb_mode;" through borland's c++ builder.
I could analyze the export table of the libspeex.dll. Unfortunately I could
not
find an entry for speex_nb_mode.
According to the manual I have to assign the address of this constant:
/*Create a new encoder state in narrowband mode*/
state = speex_e...

Problems with Speex Libary

today I try to compile a test-file from the Documentation.
I link the libarys correct but have only one error in this line:

The error:

Hopefully I ask the developer :)

Speex encoding/decoding producing garbled audio
...y it back fine.
- I'm using Speex version 1.1.6. I've also used 1.0.4 beforehand and
experienced the same problem with it.
1) I initialize the bits, encoder, and decoder as normal (default settings
seemed appropriate):
speex_bits_init(&mBits);
mEncode = speex_encoder_init(&speex_nb_mode);
mDecode = speex_decoder_init(&speex_nb_mode);
2) I record my audio at mono 8000Hz, 16bits per sample.
3) I encode frame-sized (320 bytes) fragments. Since I deal only with char
data types, I convert to 2-byte short values first and then set the float
buffer.

Shoehorning speex is confusing a newbie
...not have enough data memory to store all the tables. I thought
this would work with my initialization but when I stepped through the
code in nb_celp for encode it would put it in mode 6 (instead of mode
3), which I believe is 18.2kbs (table 8.2). My set up code is:
st = speex_encoder_init(&speex_nb_mode);

tmp=TESTENC_QUALITY; //=4
