Audio related stuff
The mix of the technologies works very well. MS VC++.NET 2003, ATL, WTL – for development environment MS DirectShow of DirectX 9 – for multimedia infrastructure Intel Integrated Performance Primitives 5.0 – for standard code implementation base All together – AMR GSM 06.90 Speech Codec DirectX Media Object (DMO) as shown below: Runtime requirements include:…
So, DirectX Media Objects (DMO) appeared to be a nice interface to extend DirectShow functionality. I could quite easily create encoder/decoder pair of DMOs for AMR speech coding (GSM 06.90). Reasonable ease and development speed. I will probably even prepare an informational version and put here on website. It is likely to contain forced silence…
How could it happen that an expreienced DirectShow guy only recently discovered DirectX Media Objects (DMO)? And the idea is really nice. Definitely got to check this at work with some audio processing.
Undoubtedly from the very beginning, the idea of sound source localization is far from being new. However, while it’s brewing up in the head it gives more and more keywords and finally I got a lot of theoretical and practical findings in this area. Still the Q is if there is any practical progress, something…
Similar to what I wrote recently: On the up side, if it CAN do this then with a map of the ‘known’ positions of the microphones it could probably also plot the relative location of each source of sound in the room much like a submarine sonar. If you place a few microphones at floor…
I wonder if there is any progress in estimating audio source position by simultaneous recording from several points (3+ I believe). Thinking a bit of this funny feature, I thought it might be quite useful. For example, to remove background noise before speech recognition. Or to record a conference and split audio by the person…
