similar to: How speex cope with the difference of frame length?

Hi,I am using the speex 1.2rc1. ? I wonder what is the relation of 3 parameters as follows. ? --quality n??????? Encoding quality (0-10), default 8 --bitrate n??????? Encoding bit-rate (use bit-rate n or lower) --comp n?????????? Set encoding complexity (0-10), default 3 ? Providing I wanna a certain speech quality in 8khz, how should I set the 3 parameters? In my coarse and old opinion,at least

Steve, The main problem I am having with the system is clipping off the start of someone's speech when they first start talking- the ends of the sentences seem to be handled properly. I am wondering whether this is the fault of the audio playback system or whether this is a speex issue- I also get the musical artifacts problem with the denoiser. This seems to be more of a problem on open

Jean Marc, Thanks for the advice. The estimate update may come in handy. I have had some time to play with the adaptation time. I tried making the adaptation time 80, 160 and 320. It seemed like the smaller value was actually the best in my initial testing, but I need to test this against a more noisy setup than I have here. I am guessing that for vad a shorter adaptation time is probably

I'm not sure if this is due to the same problem, but I get the same clipping behavior when trying to use VAD+denoiser on a particular mic+speaker setup that has significant background noise (enough to really foul up the codec should the denoiser be turned off.) Leaving VAD off and transmitting continuously seems to be the only way to avoid this clipping. Another person I regularly

Hi, I don't think this is the right list but since it is the only speex related list on the XIPH list, her it goes. Flame away if you wish or, if your feeling generous, tell me what list to post on. How do you "denoise" only without compressing the file? The documentation implies it is possible. It says on page 9 of manual.pdf, "The denoiser can be used to reduce the amount

These are my results with the Speex AGC and denoiser: Over the past couple of months, I've spent probably 10-20 hours of conversation with Speex (wideband) doing AGC + denoiser on both ends of the call. I think it does an excellent job of removing most noise while keeping speech intact. Yes, it's possible to make some constant noise (like humming) and have that get removed, but

hi there, I am new to mailing list so excuse me if I don't obey to the 'netiquette'. i am writing voice chat and speex is in the root of it. i write it in Java and use JNI to link with 'C'-based Speex 1.2beta. [I know of JSpeex but there are not implemented some features] recently i decided to use DTX feature of speex as well. the code follows. The problem is that no matter

I believe there is a documentation error regarding speex_preprocess_ctl(preprocess_state, request, ptr); The manual states: SPEEX_PREPROCESS_SET_DENOISE Turns denoising on(1) or off(2) SPEEX_PREPROCESS_SET_AGC Turns automatic gain control (AGC) on(1) or off(2) I noticed that setting a value of 0 turns the setting off. Setting a value of 1 or 2 turns the setting on. While I do think 1 and 0 is more

Hi, Thanks, that gave me some ideas. I have tried calling speex_echo_cancel and speex_preprocess separately and jointly, with a number of different filter lengths, and using the cancelled and non-cancelled data as input to the pre-filter, with and without the residual echo, etc. but there doesn't appear to be valid data in the echo or the cancelled frame any way I try it. Back to the

Does setting message=FALSE in the chunk options of the vignette help? Or less preferably, using supressMessages() ?

Hi, So I have had a chance to delve deeper into the new pre-processing code- I was also able to get VAD, AGC, Denoising, etc working inside of the current release candidate (1.0.3). For some reason, the 1.1.2 release didn't properly encode/decode in our system (on windows) and I haven't had time to determine why. In any case, all of the features jointly work very well- great job! I

This is only remotely related: just out of curiosity, does speex_preprocess work very well for you ? It only works to certain extend for me, and does not seem to completely remove noise from sound card. Even if you unplug the microphone, it still could not get rid of the noise. Any idea how it could be totally eliminated ? <p>Thanks <p><p>-----Original Message----- From: Tom

Tom, You can look in my archives for my posts on this topic, but what I've found is that the echo canceller works to some extent, but if you're also using the other preprocessing (which you'd definitely need to do _after_ ec, otherwise ec probably won't work at all), the AGC function ends up reversing the effect of ec. That is, while ec reduces the echo, it doesn't

I don't think the echo canceller works yet. The best I could get it to do is trash my audio. If it does work, some sample code demonstrating its use would be really appreciated... Here is what Jean-Marc has said about it in the past: > What should I use for a filter length for speex_echo_state_init()? "Well, it depends on your problem. The filter length represents the maximum

Hello, I think `quietly` should only silence normal masking messages intended for users and providing information about normal behaviour, such as masking. This is not the case here as the message is about overriding of S3 methods, which has global effect and is rather problematic. It may change behaviour of package and script code in unpredictable ways. This is not something that the user can
