New tutorial up – stupid cell-phone tricks

Ok, ok, I know it took me 10 days, but I got another tutorial up. This one covers the highly discussed topic of center channel extraction. I talk about the pros, cons, and even show you a couple of simple ways to do it. You can check it out here.

Ok, as I stated in the last update, the reason it was taking me a while was I’d been concentrating on playing with Speex and writing an HLSS tutorial. I’ve done about enough exparements with Speex and I’m in the process of writing the thing, but it’s starting to get VERY technical…it may or may not be the next published tutorial.

The other reason was this past weekend I picked up a Moto Razr V3m on a prepaid Verizon deal…and then proceeded to hack the shit out of it. In doing do I enabled USB transfers which allow me to do to several things…which a few of them were prevented by the network (I *ALMOST* had wireless internet anywhere), but I did enable the USB/Bluetooth transfers which allow me to not only pull the photos and “flix” off my phone without paying network fees, but I’m also able to upload mp3’s for use as ringtones…and I’ve spent the last few days making a bunch (then fixing Vista when the USB drivers killed other drivers)..and ok, ok…I did slack off and head to Kings Dominion with the family on the 16th…which is where I had gone not but 20 days prior…worked out, i rode some stuff i missed the first time around. I did ride thier new coaster…I wasn’t that impressed.

more tutorials to come…research is hell

well, the general word from the community is my first tutorial was well written, even i have to admit that after i finished assembling everything and looking at the published page; I was somewhat impressed i was able to create something like that.

needless to say, i’ll be working on more tutorials in the future. i already have one written up on the commonly discussed topic of “middle channel extraction”, which is removing all the audio that is mixed to dead center (and is also in phase), however my twist will show you how to retain the original stereo image, along with how you can extract just the center channel and discard all the stereo bits. it’s not that hard to do and really is the work of two plugins, however, the topic comes up, people want to know…so i’ll show you how to do it.

also, another topic that’s been discussed recently over on the gw forum at least twice that i know of is making music sound good when using HLSS. since this is basically the same process as making audio sound it’s best when using the limited-bandwidth codecs designed solely for the human voice, i’ve decided to write one up on that as well, but i’m finding all kinds of funky effects of processing depending on the voice codec i’m using, so to save time, the tutorial is going to focus on the speex codec..and since i’ve never used that one before..guess what…i get to have all kinds of fun throwing various signals at it so i can make notes of it’s actual behavior and make a good tutorial…however the same process could be applied to other voice codecs…and will make some low-bitrate codecs designed for music sound “better” (basically dynamically compress the whole #!) (shebang for you non-unix people…if i had wanted to censor myself….well..i wouldn’t have to begin with)

so, that’s just to let you know what’s up.

False-Positive Virus reports in Goldwave’s uninstall program.

It was reported the other day that AVG 8.0 reported that the unstall.exe program was infected with the trojan Downloader.Banload.WPR; and apparently Kaspersky was reporting Banload.OHF. These are false-positive reports.

Chris, the author of Goldwave, has verfied that the files from the website and download affilates are not infected with any kind of virus. Several other users have reported not having any detections.

It is 100% certin that these are false-positives..and so far have only appeared in AVG and Kaspersky, although it seems as Kaspersky has fixed thier definitions and it is no longer reported.

audio-news scrapped…tutorials in

we’ve decided that maintaining a site about audio-news was probably wayyy too much work and not in my personal interests…plus the staff quit. so, musichack is now basically about digital-audio manipulation; mixing, mastering, editing and various stages of production.

our first published tutorial is “seamless loops and splicing audio“. demo files included so you can actually try the tutorial.

 

stay tuned for more.
