When I was trying to find yesterday's xmms-plugin bug, i have noticed that seeking in stream without seek-table isn't very good.

I think I've gotten FLAC__lpc_restore_signal() about as good as I'm going to get it. Here's what I have: -a new file, lpc_asm.s, which has the assembly routines -changes to cpu.h, cpu.c, and stream_decoder.c to enable them -changes to configure.in to support the new cpu stuff -a preliminary Makefile.am -maybe something else I'm forgetting Now automake complains that configure.in doesn't define CCAS and CCASFLAGS. A bit of research suggests that I could just do that directly, but does anybod...

...ke it to CVS, so here is another try. I made some benchmarking with the test_seeking utility from flac sources to show how bad the current seeking is, especially without seektable. Track used for the experiment had about 50 minutes. In the following table is average number of seeks and number of decoded frames required for one complete absolute seek. I tried several files encoded with fixed/variable block size, seektable with seekpoints every 10s, 100s and no seektable. unpatched patched block size seek decoded decoded points seeks frames seeks frames fixed 10s 1.22 2.04 1.16 1.83...

Thank you for the feedback. This is cross-compiling for mingw-w64-x86_64 using gcc-5.3.0 and mingw-w64-4.0.4 on GNU/Linux. Upon attempting to compile now, a large number of errors occur in flac/decode.c which I have placed at the end of this email. They are eased by adding this to decode.c: #if _WIN32 #include <windows.h> #include <shlobj.h> #endif ...among the headers. Then, this error results when attempting to link flac.exe: decode.o:decode.c:(.text+0x4fe1): undefined referenc...

Hi All, We are using speex decoder only for narrow band decoding. Quite often, even though source frame is not silence, decoded audio is silence. I wonder there is a problem in the way we uses speex decoder API. Basically, we initialize speex decoder only once and just reset the decoder before we decoding another file. Do we need t...

Because a wideband signal has both a narrowband part and a wideband part the first part of the wideband decode is to call the narrowband decode. In the fixed point version the signal generated from the narrowband decode is downshifted at the end. In this same version the wideband then upshifts the signal by the same amount. I would like to do away with the downshift on the narrowband side and the up...

To avoid crash caused by an unbound LPC decoding when predictor order is larger than blocksize, the sanity check needs to be moved to the subframe decoding functions. --- src/libFLAC/stream_decoder.c | 30 ++++++++++++------------------ 1 file changed, 12 insertions(+), 18 deletions(-) diff --git a/src/libFLAC/stream_decoder.c b/src/libFLAC/stream_decoder.c index d13b23b..211b4db 100644 --- a/src/libFLAC/stream_decoder.c +++ b/src/libFLAC/stream_decoder.c @@ -1281,9 +1281,6 @@ FLAC__bool al...

Hi, I just started using speex recently and I've been having problem with Speex ver. 1.1.10 decoder. I used Speex to encode a wav file to spx then decode it back to wav file to see the voice quality that results from different speex options. Somehow, I couldn't get the original wav file back. I used both Speex ver 1.1.6 and ver 1.1.10 to both encode and decode, despite the same output file s...

Sorry, it seems I have only replied to Lakhdar, not to the newsgroup. Below is my reply to Lakhdar, and I would like to make it more clear now, using some pseudo values for simplicity: I read bytes 1 to 124 from my encoded spx file. I decode themt and get the values: ---Frame 1---- -293 -8234 2134 17 ---Frame 2---- -9323 -732 189 2329 Both frames are just perfect as I need them. But now when I read bytes 63 to 125 from my encoded spx and decode it, I get the values 732 9273 -799 -723 This is weird because I expected to get the enco...
