    Phoronix: [email protected] 2009: RandR 1.3, GEM, Gallium3D, Etc

    All of the recordings from the X.Org meetings that took place during FOSDEM 2009 are now available on Phoronix. There were nine topics in total from RandR 1.3 to shader compiler optimization strategies. Novell's Matthias Hopf had explained RandR 1.3 with all of the work involved in this update to the Resize and Rotate extension for the X Server that now has panning support and other new-found capabilities...

    Thanks for incorporating our suggestions about audio quality warnings, and links to easier-to-download vids, that were posted in the forum thread about the previous article.

    Let's just blame Pulse Audio for the sound problems. It has certainly caused all of my Linux audio issues for the past year. In fact, Pulse Audio is so awful I'm sure some researcher will soon discover it even causes cancer, AIDS, and global warming.

    Okay, maybe not cancer and global warming, but after attempting to watch the aforementioned videos, it nearly did give me AIDS. (Well, hearing aids at any rate...)

    That, and the fact you don't see the speakers on most videos (seeing the speaker can be a great help). I'd rather see the speakers than have a video of the slides (for the slides, a link to the .pdf is better than a youtube video).

    I'm not sure how the adapter (usually just a piece of conductive metal) could have caused the problem. It doesn't sound like normal interferance noise, more like the noise you get with bad microphones or lack of a preamp.

    Since you used a quarter-inch to mini jack adapter, does it mean your microphone was a HIFI/Sono microphone, in which case the mic in of any computer would provide insufficient gain (i.e. you can get loud enough sound, but you'll have to increase the gain so much you'll get the noise cranked up too)? For those you'd need a preamp between the mike and your computer mic in.

    There's mostly two types of microphones:
    - the ones for computer, that can be plugged on a computer mic in as is, but don't provide great sound unless the speaker takes extra care (impossible to use in a setting like these talks - you'd get same result you had);
    - the ones for HIFI, that provide good audio, but need a preamp before you plug them on a computer (since they're not made for computer use - without a preamp you'd also get the same result you had).

    There's also the mikes that comes with a preamp built in, which are easy to spot since you'll usually have to provide batteries.

    What made it bad for me is that many of the speakers had very heavy accents (as compared to mine anyhow ;D), they can be tough to understand normally, let alone with noise and buzzing going on.

    Also not being able to see the slides or the speakers made the video pretty much useless.

    I think this was a netbook with a microphone

    As for Michael, it's ok, first times are always like that, you need to learn the hard way

    Best setup :
    * a sound recorder with line-in, a sound cable with different Jack sizes for when you can convince the sono to plug it in;
    * a mic, a preamp and a sound recorder (with plenty of spare batteries) for the other cases. Preferably a sound recorder with internal mic too for the times the connection with the mike is bad.

    Never trust cameras for sound recording...

    Bottom line seems to be that Michael was getting decent audio when he checked it, but the adapter was crapping out randomly during the sessions and the problems weren't noticed until after the sessions had finished.

    You can listen to the talks (I've listened to about half so far), but (a) you need a fast hand on the volume control, and (b) you need to use your imagination to fill in the gaps where the noise overwhelms the speaker's voice
