Fantastic! Thanks Tom.

Please help me interpret the following results. The full model (Schwa~Dialect*Prediction*Reduction) was reduced via both update() and step(). The minimal adequate model is: ancova<-lm(Schwa~Dialect+Prediction+Reduction+Dialect:Prediction) Schwa is response variable Dialect is factor, two levels ("QF","SF") Prediction is factor, two levels ("High","Low")

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

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...

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?

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

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?

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

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

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

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?

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

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

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?
