rtp payload lenth
Hello to all speex developers, I have question regarding payload length of narrowband speex in RTP. I were watching tcpdump of the xlite softphone and have found that it uses weird payload length namely 75 Bytes I went through various source and without success. To be clear: For 8000Hz sample in 20 ms that is 160 samples per frame. This makes 50 frames per sec. modes bit-rate 8 kbit/s

Does VAD/DTX work without VBR and Preprocessor
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

VBR quality...
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? Thanks. --------------------------------- L'email della prossima generazione? Puoi averla con la nuova Yahoo! Mail -------------- next part -------------- An HTML attachment was scrubbed...

Does VAD/DTX work without VBR and Preprocessor
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?

A Question about VBR
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

ices and VBR mp3s?
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?

Change target VBR on-the-fly?
Josh, Yes, you can change VBR quality or ABR average bitrate at any time. You don't need to do anything special. I use this feature (changing VBR quality midstream) from time to time and it's quite convenient.

Structure of VBR in FAT32?
Hi Syslinuxers, I am trying to understand the basic load chain in fat32 and ext4. I dug into the assembly for MBR, which is pretty straightforward: 1. Find boot partition (or use the pre-defined one at byte 440 for altmbr.bin) 2. Load the first 512-byte sector of the partition (VBR for fat32, Block Group 0 padding for ext). 3. Execute that code The code that is loaded, however, has to be too

vbr and music
I know speex is not supposed to do a great job compressing music, but I've noticed that the new VBR code chokes completely when you try to compress horns. I've placed a particularly offensive example up at http://www.utdallas.edu/~matthias/ . Take a look at a-16m*{ogg,spx}. a.ogg is the first minute of an ogg created from the source media (in 44khz stereo). The rest have been mixed down

VBR conflicts filesystem?
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?

Help on Speex VBR mode
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

VBR vs ABR
Hello, I purchased the "CD Ripper 2" plugin for Winamp 3 and need help choosing an ogg encoding format. It seems I have the choice between VBR and ABR formatted oggs. I am familiar with VBR (variable bit rate) but not sure what ABR stands for? Is it possible/desirable to specify a bit rate when encoding oggs, or does the nature of the ogg format make use of varying bit rates?

Should Speex VBR Introduce Distortion?
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

Opus for speech: VBR vs CBR
Hi guys, I'm using Opus for speech in wide-band mode (sampling rate 16000) and 20ms frames with signal type set to SIGNAL_VOICE. I have a few questions here: 1. When I choose VBR mode, the codec seems to choose the bitrate on its own. However, that seems to be an issue on mobile devices. In some cases, when I configure the bitrate to say 20kbps, I see that the outgoing codec bitrate at

Speex: complexity, VBR, ABR, CBR, quality
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?

Structure of VBR in FAT32?
Sorry for the late response. I am set to digest on this list.

Does VBR work for speex in non-float platform now?
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.
