Careful when looking at W because of how the real and imaginary parts
are packed in the array.

Fixed-point scaling of mdf impulse response
Hi,
I made a small error in the impulse reponse function; when doing the
inverse fft in fixed point, it will overflow unless it's properly scaled.
This patch uses the same scaling as that used when updating the filters,
and the outputs now have the same shape and the same scale in fixed
and floating point.
Best regards,
Thorvald

The other kind of microphone problems
Hi there!
Recently I bought a simple Headset so I don't have to use my webcam mic in Teamspeak
anymore. Its a normal analog Headset, so no USB. I plugged it in my Audigy2 and it works fine.
The thing is, when I'm in Teamspeak starting Wine (wincfg is enough) it seems to "lock"
the Microphone input of my Audigy2. Then I only can use it inside Wine and only hear what the
others

Rosetta Stone V 3.3.5 Microphone Detection
Hi, so I'm rather new to Linux. With a little bit of fiddling I was able to install Rosetta Stone (version 3.3.5). I'm running the latest versions of Wine and Ubuntu.
Everything in Rosetta Stone is working great, however, it can not detect my microphone (which is not a USB headset, it is built in). I can't think of what could be wrong, as the microphone itself works fine in Sound

trouble getting speex_echo_cancel() to work
Hi,
A couple things you may want to check:
- set sampling rate to 8 kHz (at least for now)
- make sure the far end signal in the playback signal is always a bit in
advance (never late) compared to the mic signal.
- Set the tail length to something around 100 ms.
Also, if you're using two different soundcards (as I understand) for the
playback and the capture, you're *never* going to get

Re: Rosetta Stone Microphone Detection
The original post in this thread was never answered, and I too was requesting help on the same subject -since as of yet, this issue remains unresolved.
So, to recap, Rosetta Stone is installed and running, but can't detect my microphone (analogue, or the USB headset that comes with the software).
Since Rosetta Stone is reported as fully functional under WINE, I am asking for advice, in terms

Best Headsets for a Call Center Environment
I'm looking for suggestions as to the best multimedia headsets for a
call center environment.
A few considerations:
1) USB headsets are preferable, because they don't require a soundcard.
2) Omnidirectional microphones are problematic, because they pick up too
much background noise.
Thanks,
Matthew Roth

[headset/mic] Volume too low + echo in *
Hello,
I'm having the following problem when using a headset on XP
connected to an on-board Realtek soundcard on an AsusTek M2N68-AM Plus
motherboard:
- Using any sound recorder (Windows', Audacity, XLite), the level is
just too low when speaking at a conversational level, even with the
microphone level pumped all the way up (line displayed totally flat in
Recorder)

Will the echo canceler or preprocessor work with 10ms frames?
I am trying to use the speex echo canceler and preprocessor with
sipXtapi to develop a sip user agent. the sipXmedialib call flow graph
uses 10ms frames and I am not sure what the implications are if I try to
change this. The documentation seemed to indicate that a 20ms frame was
recomended, but it didn't go into the consquences of using other frame
sizes. We are going to use headsets

R2D2 VOIP Kubuntu 8.4 Ekiga, Ekiga.net voice conference
I'm having a problem getting a good clear output sidnal from Ekiga to a
VOIP conference call using the Ekiga.net free conference call system.
I'm told that each time I speak, my voice is clear & intelligible for
about .5 - 2 seconds, but then it starts to be garbled, sounding like
the sounds R2D2 makes.

To all:
I am having an echo problem with X-Lite and iaxComm. I am using the

from the speakers is repeated by the microphone causing an echo that is
annoying. Is this correctable? I have searched throught this archives

Recommended USB Headsets ?
Hi, we are looking to roll out PBX IN A Flash at our office.
The first group will be using Soft Phones (X-Lite appears to be the best
and works in Windows, Apple & Linux).
There are many types of USB Headsets to choose from and a fairly broad
price range. Is there any USB headsets people would recommend?
I'm specifically interested in acceptable audio (speaker and microphone)
