Hi everyone, I've recently done some major internal changes in Speex aimed at reducing RAM (by nearly a factor of 2!) and improving quality of the fixed-point. In doing so, I might have accidently broken a few things. I'd like to hear feedback on the current svn code to make sure I fix any regression before the next release. I'm already aware that --enable-vorbis-psy is broken and

In bits.c\speex_bits_pack there is logic to reallocate the bits buffer. In that section there is a call to speex_memset_bytes which appears to wipe out all the old bytes. I found when I encoded a multi-frame message that needed less than the default 2000 bytes for bits->chars, everything worked fine. However, when I encoded a longer message that triggered the realloc code in speex_bits_pack,

When encoding many frames, I get a write access exception. It appears the "bits" structure has a fixed-size buffer (allocated in speex_bits_init()), and speex-encode() pukes when it overruns it. I understand I could just initialize bits with a bigger buffer, or watch the buffer and stop encoding when it gets full. But I don't want to care about compressed frame sizes, nor *can* I

...cause these processors have 16 bit char size, there is some special code in bits.c to handle the packing. As part of this, there is code to swap the byte order for each 16-bit char within speex_bits_write. There is no such byte swapping in speex_bits_read_from, speex_bits_read_whole_bytes, or speex_bits_write_whole_bytes. For consistency, the byte swapping should be done in all four places or in none of them. In my present build, I have byte swapping in all four places, but it seems cleaner to take this out and leave it to the calling function to do the swapping if it is needed. The demo builds are not aff...

Hi, I want to take a .wav and generate a bytestream that I can feed direct to speex_decode(). The speexenc program appears to produce it wrapped up in an ogg stream, and it doesn't have any sort of "raw" mode. I've tried hacking on it to remove the ogg parts, but I must have got it wrong, as my decode dies after decoding 160 bytes (which I believe is one frame) with an
