2 questions, frame size and SPEEX_GET_LOOKAHEAD
...o if I don't want those padded zero after decoding, I assume
that it is up to me to keep track of the number of zeros. Is it right?
2. What does SPEEX_GET_LOOKAHEAD do? How to use it?
In speexenc.c, there is following code:
...
speex_encoder_ctl(st, SPEEX_GET_LOOKAHEAD, &lookahead);
...
nb_encoded = -lookahead;
Can someone explain what this means?
Thanks.

libspeex crash with RC3
I tried to compress 160 samples of random garbage (range 0-500.f) at 4kbps
and got a crash in nb_encode -> forced_pitch_quant because start
was -858993460 (== ol_pitch).

(small) bug in nb_decode?

Totally possible- this is the first time this has happened that I know
of in many many hours of usage-
On the other hand, this null check isn't in my code base and it was in
nb_decode_lost, and nb_encode- so I figured it was just an oversight-

ARM w/ assembly & fixed point crash
I've targeted Speex to run under eCos with Thumb interworking using
arm-elf-gcc 3.3.3
I'd written a small test case to verifiy the operation:
#include <speex/speex.h>
void
speex_test(void)
{
SpeexBits bits;
unsigned int frame_size;
void *enc_state;
float *speex_frame;

int i;
speex_frame = (float *)0x00030000; /* Address of Speex data

Speex-1.1.7 seems to crash with --enable-sse (on P3/GCC-3.2)..
Hi,
To increase the stack size, you can increase the value in the
speex_alloc() call in nb_celp.c. Let me know if it solves the problem.
Also, what compiler are you using. I think some older versions of gcc
may have problems with SSE intrinsics.

Speex-1.1.7 seems to crash with --enable-sse (on P3/GCC-3.2)..
I tried building speex with SSE, and found that it crashes for me here:

TI 6xxx platform performance
I'm trying to make a design decision between a TI 6416 or DM642 (fixed
point) and 6713 (floating point) platform. The application is a 32 channel
speech encoder. (CBR only, 8khz, 8kbps)
To get a feel for the computational load, I am running 1 second (50 frames)
of voice through the encoder.
My profile of the 6416 indicates I'm at 27.4M cycles/channel. I need to get
below 720Mhz/32

Coredumps when --enable-sse is selected
System: Linux 2.4.25, glibc-2.3.2, gcc-3.2.3 (weird palindrome there), on a
Williamette core Pentium 4 (1.6Ghz) system.
I've tried both speex 1.1.5 release, and the current CVS (which self-IDs as
1.1.4), and the result is the same.
I suspect some funk in the use of the SSE intrinsics macros.

Errors in speex lib with Blackfin
Hello!
I'v downloaded speex lib 1.1.11.1.
I am trying to port speex lib to Blackfin processor.
I am using VisualDSP++ 4.0.
If I am compiling source codes with using floating point everything
ok.
When I am compiling with FIXED_POINT defined everything's ok and code
works about two times faster.
But when I am defining BFIN_ASM I am getting several compiling errors
in Blackfin assembler

libspeex crash with RC3
Narrowed it down a bit. For me the code crashes encoding the second frame if
the first encoded frame was all zeros. Can someone else reproduce this or am
I on crack and should look for a bug elsewhere?

Coredumps when --enable-sse is selected
Hi,
I've tried the same configure options on my system and it doesn't crash.
I have the same glibc and gcc 3.3.2 (can you see if a newer gcc works?).
Also, could you explore a bit with different options so we can narrow it
down a bit. For example, does it work with the default CFLAGS or without
--vbr or --dtx. Last thing, maybe it's the file. If so, please send me
the smallest sample

The lookahead is the number of samples you need to discard at the start.

In my application, even 5ms (110 samples at 22KHz) matters. So what

(small) bug in nb_decode?
Hi,
So I got a crash on the following code:
k1=SUBMODE(lpc_enh_k1);
k2=SUBMODE(lpc_enh_k2);
which in the newer codebase is:
bw_lpc(SUBMODE(lpc_enh_k1), st->interp_qlpc, awk1, st->lpcSize);
bw_lpc(SUBMODE(lpc_enh_k2), st->interp_qlpc, awk2, st->lpcSize);
I am not sure if the newer code will have the same issue but the
following check is
