similar to: speex_denoise on non-microphone noise (static ?)

Understand that it's a *guess*. If this fixes or at least betters the situation, you're going to need to find a legit way to insulate these cards, or to switch cards. If it's for customers, I should hope you wouldn't be using enamelled aluminum foil. :D -----Original Message----- From: Tongbiao Li [mailto:tli@viack.com] Sent: Thursday, September 18, 2003 11:20 AM To:

Thanks for the speedy response and detailed, enlightening explanation. Now I understand where the problem is, and will try out your suggestions just to further confirm my conjecture. When I am done, I have to take the foil out, though. This is a product for our customers to use, and although we've got budget for mulffing every sound card we developers use, most likely the company

That's might be speex_denoise() is trying to do already, based on the fact that if noise is present in speech signal, the former gets suppressed to a certain extend. Also, I noticed after suppression, the short, noisy attack - speex_denoise() have to be doing some kind of profiling. I've looked at a few offline denoise() solutions. They all involve profile building. A real-time

The problem started with speech detection. Speech sections are detected well. However, once in a while non-speech sections are also marked as speech. The root was finally traced down to microphone static noise. Then I pulled the microphone out. Our system still records noise. To isolate the problem, I wrote a small app just to open the device and record raw samples, calls speex_denoise()

Hi, I'm not sure how speex_denoise() works, but my solution to this problem is fairly straightforward and works well in practice (in a simple VoIP program.) Note that I am also an amateur and am making up some terminology here... but I've tested my approach on several noisy environments with low-quality mics and it does work well. Problem: There's usually annoying noise present

I'm not sure you'd have much success in trying to make a generic profile to fit the "typical noisy PC" since PC configurations vary so much. Consider an integrated AC97 codec vs. the mic input on an SB Live!/Audigy Live!Drive, or whether or not the input from the CD-ROM audio is muted, or what noisy devices might be situated near the mic. It's nice to be able to get

Hi, There seems to be some confusion as to how speex_denoise (now called speex_preprocess) works. Unlike what some here assume, the noise estimation is not done offline or while prompting the user. The system automatically adapts the noise estimate when it detects that the user is not talking. This also means that it is able to adapt to changing noise environments - as long as the noise is not

Is there a more elegant way to do the following without disabling digital signing? What if I have an app requiring digital signing I need to connect to the W2K3 in the future? For explanation have the following; 1. Linux server running Samba 2.2.8a 2. Linux server running Samba 3.0.10 3. Window 2003 Server Standard SP1, not running Active Directory or as domain controller. 4. Windows XP Pro

Hello all, I have a new Carrier Access Adit 600 and am having a problem dialing out and receiving incoming calls. After the initial ring, the calling party will here nothing. There is a silence, but the SIP phones that is supposed to ring will ring. The calling party will not hear the sound of the ring that * sends out on the line. Additionally, if someone picks up the receiver there is no

I noticed that on the front page that there is a little well deserved lite hearted jocularity about being on the Evil Empires radar screen with the revelation that they are blocking wine users from using the update service. Is it just me or does this concern anyone else that the next step could be for the Evil Empire to let loose the land sharks, with patents in hand, now that we know that they
