Hi, I already implemented and posted a patch to do this serialization a few weeks ago. http://permalink.gmane.org/gmane.comp.audio.compression.speex.devel/6913 It is not integrated into the main git tree though.

Perhaps you could add a warm-start to the AEC, such that the parameters start near the correct values on all but the first use?

This is not part of the current API. It shouldn't be too hard add a serialization routine for SpeexEchoState.

Hi, Arun and me are working on a echo-canceler module for pulseaudio build around speex. When using the preprocessor's echo filter, specifically in combination with denoise and AGC, it's unclear whether these have to run before or after the AEC. Right now we've got one instance of speex_preprocessor doing AGC and denoise running before the echo canceler; and a second for echo

Hi, gurus! I'm now using PCM codec in my application and plan to apply AEC to my app. My question is whether I can use AEC module of speex. AEC module of speex can work for PCM codec, too?

But this will make it more important to reduce HW/SW latency so that you don't waste

Hello, We are experiencing a few problems with Speex AEC. We are using it to process audio data on a real time stream over IP with Speex codec (frame size = 320). We initialize the echo state like this : SpeexEchoState * echo_state; echo_state = speex_echo_state_init(320,512); int sr = 16000; speex_echo_ctl(echo_state, SPEEX_ECHO_SET_SAMPLING_RATE,&sr); We are not really sure about

? hi all, i am using the Acoustic Echo Cancellation from "Speex 1.1.12 version" in my VOIP application. Is it that the frame length to be chosen should always be 20ms or can i have flexibility in chosing the frame lenght? on what parameters does the frame length choise depends? thank you all, Shri. -------------- next part -------------- An HTML attachment was scrubbed...

Hi, I migrated from my the main domain controller.I use Centos 7 server with tranquilrepository. The destination server is a test enviorement with different domain name but the same system specifications. I can browse the sysvol network share without any problem. If i want to check the sam.ldb file on the test server I got these errors. WARNING:Module [samba_dsdb] not found - do you need to

Simply to say, in a quiet room, you can play a impulse signal and then find it's impulse response signal from the microphone. For example, if the delay between the impulse signal and its response signal range from 500 to 3000 cycles, you can buffer the far-end signal to 0-300 cycles and set the filter length to 4000. It is also called to align far-end signal and near-end signal. BTW: Speex

Hi Anton Thanks for the info... What if I use this function do I still need to sync the playback and capture? Assuming that the captured voice (*rec) already contains the echo which I need to cancel out... -------------------------------- void speex_echo_capture (SpeexEchoState *st, const spx_int16_t *rec, spx_int16_t *out) Parameters: st Echo canceller state rec signal

I have a recorded conversation from an analog trunk. As usual one side is stronger that the other one. In my case, the gap between signal levels are even bigger. How does speex AGC preprocessor will perform on this type of audio recording? Maybe I am wrong and AGC is not really what I need to equalize the two persons in my phone conversation? As I Understand, AGC will perform better if each

Hi, I successfully migrated my GPO policies in a new installation of domain controller. After I joined a Windows 10 machine to the domain the gpupdate /force command printed this errors all of my policies. filtering not applied (empty) On the server side everything looks fine. I checked the tdb files under the /var/lib/samba/private/sam.ldb.d/ folder. The

Forgive me, I'm a novice. Consider that today I have already set up a working postfix + Dovecot server with userdb using the static driver and passdb using a password file (in the format <username>:{hashing algorithm}<password hash>). The Dovecot server has several mailboxes which are already in use today. I understand that I'll need to change over to using the passwd-file

Since I don't seem to be having any luck with the classicupgrade, I decided to try starting from scratch and then adding users. I ran the command: /usr/local/samba/bin/samba-tool domain provision --realm=<my realm> \ --domain=<mydomain> --adminpass 'mypass' --server-role=dc \ --dns-backend=BIND9_DLZ Then I tried both adding and changing users.
