Hi All, I am working on VBR fixed point conversion for our DSP processor and in the algorithm the MIN_ENERGY and some more terms which I am not able to understand how those numbers are derived. Can some one help me with some documentation on algorithm discription of VBR?. Regards, -Prasad

Hello, I'm using Speex Preprocessor to supress noise, eliminate echo etc. But I have another preprocessor state that I want to use ONLY to determine voice activity. int res = speex_preprocess_run(m_VADOnly, (spx_int16_t *) pStreamSampleBuffer); pStreamSampleBuffer is modified after call to speex_preprocess_run. I have manually turned off noise suppression and AGC but anyway - VAD modifies

When i use VBR do i need to set VBR quality or speex quality? Is the speex quality referred to the overall quality and instead VBR quality only if i use VBR? Do these qualities override each other?

Hi Marc, Thanks for your quick response. So if VAD is enabled then VBR will be enable although it's a special VBR. How about take out the VAD code from the VBR and remove the code else?

Hello, I'm try to run speex on some ARM processor. I'd like to cut away some speex features including VBR, ABR and preprocessor while still supporting VAD/DTX. But I've found some puzzles in the source code regarding VAD as below, 1) there are VAD related codes in the source file preprocess.c. Will VAD still work If I don't use the source file preprocess.c? 2)The speex manual

Congrats to the team for 0.10.0. It sounds really good in the tests I've done so far. I'm really looking forward to the 1.0 release. One question though: could you explain briefly the difference between VBR and unconstrained VBR? And, in my case, the $64K question: is there any situation where CELT could produce more data than specified by nbCompressedBytes when encoding? Thanks

Hi All; If someone used speex and has experience with its settings, then who can help to explain the following: 1) When it is recommended to use VBR (vbr => true)? 2) If there relation between setting the vbr => true and the abr value (for example to be 0 or 1 or 10) and the relation between this value and abr (true / false). 3) Any relation between the quality value and the abr value?

For a bootable usb drive, syslinux seems use MBR and VBR to find vmlinuz and ramdisk. And VBR stays in the first sector of partition, 63rd for example. So does VBR conflicts the filesystem on partition?

I have a work to do about the VBR mode of Speex and the way it works. I must study the vbr.c file. I get the global idea about what the code does, but I'm not able to describe it in details. So I would like to know if there's somewhere a documentation about the vbr.ccode that I could read to make me understand how it works ? -------------- next part -------------- An HTML attachment was

Hi All, We are using speex for linphone in blackfin fixed point platform. The speex version we are using is svn-14525. If we don't disable vbr by "--disable-vbr", the sound quality will be very bad in linphone. But if we disable it, sound will be perfect. I noticed in the speex.org, there is a comment like this: > >Speex 1.2beta3 is out >December 11, 2007 >The most

I posted a while back about having trouble with ices 0.2.2 being able to re-encode VBR mp3s, and the response was that ices 0.2.2 did not reencode VBR mp3s. Are there any plans to include such support in future ices versions? If so, any ideas as to when such versions would become available? Thanks, -- "Shall life renew these bodies of a truth?

Hello, I am working on a real-time app for embedded hardware. I have two questions about the variable bit-rate option: 1. Can one designate a maximum bit-rate with the VBR option? 2. Does VBR chunk the bit-rate up and down, i.e. what is the granularity/speed of the changes in the bit-rate and can that granularity be defined and/or defined on the fly? Thanks so much for your help.

I'm writing a voice communication application, and I've got a few issues that I'd like to get ironed out, but I don't know enough about the speex implementation. First of all, this application is mainly used for conferencing - many people are in a room and only 1-2 are ever talking at a time. So, always encoding and transmitting everyone's audio stream would be rather

Hi All, I've run into a small hiccup in encoding my audios with Speex. When I encode audience laughter and applause with 'speexenc' (version 1.0.1), the result is quite acceptable... until I enable VBR. Then it distorts horribly. My understanding of VBR is that it frees the encoder to vary the number of bits emitted to better maintain the quality requested, and so I would have
