Hi,all I have tested AEC on files, it works well.I have some files,one is echo file, others are echo-added files(an origin file adding echo at different delay,such as 20ms,40ms...120ms,140ms).AEC do wonderfully on those files except echo added at 140ms-delay. But ,when i use AEC in my voip project, it does feebly. Who can give me some hints why caused this.How long can sound be picked up by mic after it plays out.This is the main problem to align echo.Give me a hint. Best regards ke...

...idering leasing a new server in Germany to run my Asterisk infrastructure and I was wondering how response time would affect the performance of the system. Right now I have a response time of around 60-70ms with my server in California. The server in Germany would have a response time of around 140ms (both ways). My DID/Termination providers are in Canada and the USA, and all my voip boxes are also in the USA. Any suggestions or recommendations? Thanks in advance!

...made to run fast on a DSPIC33 by the following strategy: Make iir_mem16() (for example) purely 16 bit by restricting the number of bits in the signal to say 10 using SATURATE and then making the LPC co-efficients just 6 bits. At present (with standard code) the encode function is taking about 140ms which is seven times too long ! Any thoughts welcome ? Best wishes for sunny September days. Simon

Does anyone know the default E&M Wink timings for Nortel DID ports? The default settings on Asterisk are: ; prewink: Pre-wink time (default 50ms) ; preflash: Pre-flash time (default 50ms) ; wink: Wink time (default 150ms) ; flash: Flash time (default 750ms) ; start: Start time (default 1500ms) ; rxwink: Receiver wink time (default 300ms) ;

...vers on in the US and one in Hungary. I want to mount a share from the US server here. But file transfers are very slow. (Never more than 22kbytes/sec) The bottleneck is in the US the T1. The architecture looks like: Fileserver -1Gb- Server -T1 (GRE TUNNEL)- INTERNET -100M- HunServer The ping is 140ms. It *must* be samba related thing, cos the FTP over exactly the same route gives me 195kb/sec. I suppose that the latency is the problem here because of the principles of the SMB protocol.:( If it is, can anyone tell me a solution to mount directories remotely. (NFS was fine, but after some time...

Hello, Recently I''ve received some complaints that there is excessive but intermittent latency of network traffic to domUs on some of my servers. Upon investigation it seems that on some servers, indeed traffic is occasionally delayed by up to 140ms where something like 5ms RTT would be expected. The average RTT is not unusual; since this is only occasional packets it only affects the worst case and standard deviation. What seems likely is that these servers are overloaded for CPU. I have tried the various tweaks of the credit scheduler but t...

Why ov_open_callbacks(fd_, &vf, NULL, 0, OV_CALLBACKS_NOCLOSE) takes so long to open OGG file? The OGG file has just 210 MB. It takes a lot of time open the file. I am working on OGG audio recorder and player. Thanks in advance! With kind regards, Pavel

I''ve got a javascript that provides me with the timezone for the client. I want to use this to set Time.zone so that all my times stored in the database are displayed in the timezone for the client. So really simplistically var timezone = jstz.determine_timezone().timezone Time.zone = timezone.olson_tz obviously this can''t be done. I''ve taken a look on the web and can
