Goldwave’s DNS is down.

Filed under: Uncategorized — dewdude @ 9.50.pm

UPDATE (4/25): Chris over at Goldwave knew about the problems, it appears there was a snafu with DNS authority changes. The problem went away yesterday (or even late thursday night) and things are working normally.

It appears the dns in charge of goldwave.ca has gone AWOL. The domain isn’t even close to expiring and I haven’t really bothered digging as to seeing just wtf happened. But here’s the work around.

If you don’t already know how to edit your OS’s hosts file, then google for it, because that’s what we’re going to do. If you already do, then you’ve probably figured out just what to do. For those that don’t, the HOSTS file baiscally defines a set of names and the address associated with it, bypassing any DNS queries. By telling your OS what goldwave.ca is, it doesn’t even bother looking it up and through the magic of http headers that virtual domains, it’ll work just as it did.

69.49.101.51 is what goldwave.ca normally resolves to.

Goldwave.com and goldwaving.com are unaffected, but forums are located on .ca

musichack likely moving – new Goldwave news.

Filed under: Uncategorized — dewdude @ 10.31.pm

i’ve been debating for a while on if I should move the blog/site over to my new server or leave it here at wordpress..and I had thought I’d leave it here, since people know about it, however, I will likely wind up copying the current content to the new server and updaing things over there…probably without the help of a blog system…going back to the traditional ol’ HTML. Not sure what the new domain/address will be, however, I will keep you posted and the move won’t happen till I get a NEW tutorial written.

There’s also some updates on the Goldwave front. Goldwave was recently made a registered trademark of Goldwave, Inc and I’ve made the notes in the footer of the tutorials to indicate that. I still would like to thank the developer, Chris, for allowing me to use screenshots. He’s also brought news on his website of current status of GW development, among many improvements we can expect to see in 5.50, here is a small list:

  • complete Unicode support for for better international support
  • Integrated GWVoice Plug-In
  • Higher Resolution frequency visuals
  • High Quality polyphase resampling
  • Accelerated multiprocessor support

There is also a new “loop play” function which, rather than playing the ENTIRE section to see if it loops, will play just before the end of the slection and just after the beginning, so no more listening to the ENTIRE segment listening for the loop.

Licenses will cost $49 USD or $59 CAD. Purchase at the current price of $45 USD and recieve all the GWVoice Plugin effects with the next update; and as always, your license will work for future releases of Goldwave. That alone is worth the cost of registering!

If you’ve already got Goldwave installed (and if you are here, you probably do), then why not register your copy today? I not, grab it, play with it, see what everyone is talking about. Regardless of your needs or skill level, Goldwave is sure to fill the void in your audio toolbox, and help is always right around the corner.

Looking at the pages, I’ve only uploaded samples (thus far) for the seamless splicing tutorial, so I’ve moved the files from the previous free host over to my server. Not sure if I’ll move the blog, but be prepared for a new location and probably a new engine…possibly not even a blog at all.

Holy crap! We’ve got a new tutorial!

Filed under: Uncategorized — dewdude @ 11.48.pm

Since I haven’t done one in a while, I thought I’d take a page from what someone needed done on the GW forum and write a new one. This one covers how you can edit your audio for video so you can drop it right in to your video file.

I also recently got a server, so you’d think I’d be moving the blog over to there, but I do kind of like the trackbacking wordpress does, so I’m considering keeping the blog over here but moving all the files over from hotlink files over to the new server.

where’s all the action?

Filed under: Uncategorized — dewdude @ 10.11.pm

ok, so it’s been a WHILE since i posted ANYTHING to the site. sorry.

i’ll admit that doing a tutorial site was probably a bad idea seeing as i don’t really think about all the processes i do when i do them. but don’t think i’ve abandoned or quite entirely..it’s taking me longer than expected to actually write stuff, but i’m working on it.

New tutorial up – stupid cell-phone tricks

Filed under: Uncategorized — dewdude @ 10.06.pm

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

Filed under: Site News — dewdude @ 3.23.am

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.

Filed under: Goldwave News — dewdude @ 1.58.am

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

Filed under: Site News — dewdude @ 9.58.pm

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.

new required information-

Filed under: Uncategorized — dewdude @ 12.14.am

i am now required to print the following message at the bottom of all my webpages, however, wordpress won’t let you manually insert a footer or let you use CSS without upgrading (paying) and since I absolutely cannot stand greedy bastards who force you to pay for something that even BLOGGER lets you do for free…..I will be moving the entire site in a few short weeks. till then, this message, I hope, will satisfy the legal requirements.
