...experiments over more than 20 soundcards, the differences range from 0.5Hz to more than 50Hz when sample rate is set to 8000Hz). Maybe this is totally caused by hardware which can't be solved by software settings. 2. Static measurement of the difference between sample rates is far from enough. Accurater measurement requires more time to record echo signal in order to get accurater frequency shift from spectral structure. However, the accuracy of the measurement is still limited and not enough for long time work of AEC. For example, in my experiment, I recorded 2^18/8000=32 seconds of echo signal,...

Hi, checkout new open source voipmonitor.org SIP packet sniffer.?I've developed it for my telco company and I've decided to share it. Testing and contributions are welcome! VoIPmonitor is open source live network packet sniffer which analyze SIP and RTP protocol. It can run as daemon or analyzes already captured pcap files. For each detected VoIP call voipmonitor calculates statistics

ok, ok, i've found the solution to my problem. if anybody dont mind, i 'll tell, what i have achieve :) let's see logical vorbis stream (actually i have no stream, coz i have rid of ogg). first three packets - identification, comments and codebooks. then goes a packet, which, as i understood, is just auxiliary for the next one. In addition, it holds (it can be found via

Hi I''m moving to hfcs (mostly succesfuly:) ), but I''ve encountered a strange problem: When I download something from this server using wget (one thread) via an idle uplink, I get no more than 130 kbit/s, and when I''m using prozilla (or start more wgets), I get about 200 kbit, but still it''s not all the link can do (240) - the rest remamins unused. Is this

During the interesting interview that binaryfreedom has made with Monty and Jack, Monty mentions cascading, a feature that will be added, quote: "Cascading is the ability to make multiple passes through the frequency spectrum, iteratively filling in more detail, like a progressive jpeg". What are the advantages of something like this - does this generally improves quality or is it used

Hi folks, My wife and I are taking a long weekend to celibrate our anniversary. I won't be around again until Wednesday to answer email or do anything else on Vorbis. Yeah, I know, I usually answer my email once a month anyway (so likely no one would notice me being gone), but just so folks know if anything really juicy comes up :-) I'll be merging my latest branch with mainline
