Oh, I forgot to mention:  You owe +Ken Fallon a show.
Yes, you. YOU! There, with the shirt, looking at the computer screen!

Get recording, dagnabbit!

(I don't owe +Ken Fallon a show, though. I owe at least 3 in the near future, because I told myself I needed to produce MUCH more audio this year...)

I've not actually listened to HPR in over a year, always got a podcast backlog, but I did do a show last year.
I have a big project on the go that I will certainly do a show about.

Is building something for Android SUPPOSED to be this much of a flaming pile of complicated crap?

I've got a bit of source-code for an older (last updated in 2012 I think) open-source really simple audio recorder app.  I want to add one line and change one line (to add a 48kHz option and make it the default).  Then, I just want to rebuild it and install it on my phone to try it.

I've now just had to download and install about a quarter-GB of crap to try to make a "project" out of this tiny thing and I still can't seem to figure it out.

Mind you, I'm still pretty ignorant of it, but I'm having a hell of a time finding documentation that doesn't assume you either started from scratch in "Android Studio" or have an already-ready-to-build project with all the shiny new "gradle" files (which seem to have replaced ant since last time I build an android app I'd modified - successfully back then...)

Grrr.

Makes me wish Mozilla was serious about getting FirefoxOS available to the general public (and not just a handful of special builds of it for a handful of special devices)...

That's the one - I just wanted to A)add a 48kHz option and B) make that the default, so I could just plug in a microphone, pop open the app, and hit record. (and have it at 48kHz because that seems to be the "default native" sample rate for just about everything these days - especially cheaper audio hardware/software which apparently frequently resamples everything to 48kHz. The Opus codec's internal processing does the same thing, at least partly for this same reason i.e. so that audio isn't getting resampled by the hardware then re-resampled by the codec most of the time...)

I haven't plugged in the microphone to try it yet, but 48kHz now shows up as an option and is selected by default.

If I get ambitious sometime, I may officially fork that codebase and try to add a menu option to choose where to save the files (it just dumps them in the root of the default storage device right now).

I can't remember if I linked this question here before, so here it is: have enough of the patents on mp3 finally matured into the public domain for it to be possible to generate any form of valid , minimal-feature (i.e. even crappier than regular mp3 but playable) mp3 files without using the remaining patented methods?

For example, about half of the remaining patents deal with stereo or surround-sound or whatever, so mono mp3 files wouldn't be restricted by those.

Of course, everyone should just switch to .opus anyway, but if legal mp3 was available it could be a fallback option for the Apple users...
The crappy-old-mp3 standard has now been around for nearly a quarter-century. Most kinds of audio players and web browsers have supported better, legally-free formats for a while now, but as usual Microsoft and (most prominently) Apple are stuck with only formats that you have to pay a ...

A fellow freesound.org user sent me a message yesterday asking (among other things) whether I had enough submitted reports on my HTML5 audio format browser test page to be able to post some results. It's been up for a few years now and I figured I probably had up to a few hundred by now and could probably make some relevant observations from it...so I looked.

I have over 8000 responses, over 5000 of which have been this year. I think that's enough data to make some observations...

I'm digging through them now to see what I can figure out (besides "browser makers are buttnuggets with their user agents". Seriously, most of these seem like they shove references to gecko, webkit, applewebkit, safari, chrome, and every other thing they can think of into the agent string, plus often some extraneous crap.)

Maybe I can get a Hacker Public Radio episode out of the results.
HTML5 Audio Formats Test. This is just a simple test/demo of the HTML5 tag with which to test browser support. Assuming you have a modern web browser with working tag support, click the "play" button in the player below to hear which audio format your browser defaults to.

Anybody know any good tricks for altering voice recordings made by one person to make them sound like different people? (Not any specific people, I just mean multiple different-sounding character voices).

Changing pitch is slightly helpful, but not nearly versatile enough. Could I do something with equalization curves, or are there any of the filters and plugins for Audacity that would be good for this sort of thing?

It is possible that I could get it through steam, if I had money (and wanted to resort to proprietary stuff - yes, I am a "freetard" :-) )

I figure there are probably some open-source "voice-changer" plugins or modules out there somewhere, though what I'm really interested in is basic "techniques" (that I can adapt myself). I haven't tried generating custom equalization curves for individual voices, for example, so I don't know how useful that might be (and was kind of hoping someone would say "oh, yeah, I've done that and it works well" or "no, that's just going to make them sound distorted" or whatever...)

Northeast Linux Fest appears to have been left to die...

There goes any chance of me getting to a Linuxfest again.

Oh, look, Google has somehow RECURSIVELY abandoned Linux users on Google Earth.

Not only is the available Google Earth for Linux a major revision behind (judging by what's getting sent by the download link), but the "Google Earth Pro" that is supposed to be "free" now doesn't exist.  Click the download link for it on Linux and get the previous version (6.0.something) of "GoogleEarthLinux.bin" (instead of a message saying "Huh? Linux? Does anyone use that? We didn't think anyone but us used Linux so we didn't make Google Earth Pro for it."...).
No "GoogleEarthProLinux.bin" anywhere that I can find thus far.

I'm not enamored of Google's services enough to bother with WINE and trying to run the Windows version. I've already abandoned the sadly degrading Google Maps in the last few years.

At this point, I only even have Google on one single Android device now (out of 6 that I still use, now!), and THAT only for Ingress. Given that I've pretty much maxed out on how far I can get on Ingress (a game of mobs, so us rural folks are pretty much up the creek without a plunger for "how many portals can you capture" and "how many times can you 'hack'" and such badges and points...hey, how about a "physical area  covered with fields" badge?) and needing a long vacation in a densely-mobbed urban area, or a year or so of persistent tedious slogging to get to the next "level", I'm not sure how much longer Ingress will even keep the tangled mass of system-slowing Google services on my phone...

(People keep complaining about how "bad" Lollipop is on the 2012 Nexus 7, but it's working great for me...on the Cyanogenmod version sans Google. I think it's all the growing pile of extra Google services and apps that run in the background that cause the problems there.)

Dammit, Google...

What have you got against proper #opus support?

(CM12 snapshot on my Nexus 7 2012 specifically to see .opus files playing in generic media players, and none of them recognize .opus files, including the stock media player..."Supported Media Formats" reference page for Android has still not been updated months later, either.)

I tried the default "music" player, "Pretty Good Music Player", and "Material Player". All refuse to even recognize .opus. (I originally assumed the latter two, at least, might just need to be updated to know .opus was a valid media type, but the inability of the default player and the bug report linked above make it look like the OS itself still has issues.)

I'm guessing they implemented support for the "codec" but didn't bother testing the codec in actual existing media files. ("Works in WebRTC in Chrome, I guess we're done now...")

I'm doing some quick, simple processing of the data from my html5 audio test/demo page.  (The fact that the "browser capabilities" file is massive these days is bogging the process down a bit...).

But I can say THIS much just watching the results so far: we should all probably just configure our web servers to drop packets from any connection that identifies itself as IE6...

It would be SO FRIGGIN' COOL if Microsoft expanded .opus support in IE to include .opus files in <audio> tags like the other two major browsers do. 

Unless things have changed drastically since last time I looked at the statistics, that'd mean something like 90% of all web browsers in use having support for a common, high-quality, low-latency, fast, and legally-free format for web audio. (Also, go vote for this, please...)

Come on, Microsoft, you're halfway there already, add <audio> support!

#opus
Ogg Vorbis and Opus are free and open-source audio codecs with great quality. They are developed by Xiph.Org Foundation and IETF. Opus codec provides the best quality (latest listening tests: http://listening-test.coresv.net/results.htm for 96 kbps and http://listening-tests.hydrogenaud.io/igorc/results.html for 64 kbps) and very low latency (http://opus-codec.com/comparison/ ).

On an unrelated note I confirmed that I can directly melt mixtures of erythritol, isomaltulose, and flavorings in the microwave to make (tooth- and bloodsugar-friendly) hard-candies.

I need to do a few more experiments.

You need to practice better safety procedures. Don't you know that those two chemicals readily combine to produce hydrogen hydroxide? And we all know how dangerous that is.

Bragging rights
I worked as a professional computer nerd to pay for my 20-year-long "4-year" degree in microbiology, and then ended up becoming an innkeeper. Funny world. I still have my microscope and actively-used collection of Linux boxen, however.

I love finding places like this - wonderful pastas made in-house here at this little independent restaurant.

Excellent "American-style Chinese" fast food. I concur with the other reviewer about the coconut chicken, it was delicious.

This is a reasonably good American-Style "Oriental" fast-food place run out of a converted trailer across from the paper mill. Lots of deep-fried appetizers, chow mein, etc. Prices are a LITTLE high but not too bad, and the portions are fairly large. Not a bad choice locally for quick take-out.

A nice little independent, old-school burger and ice cream stand, with both a take-out window and a small indoor seating area. Nothing fancy, but the bacon cheeseburger was well made (and they weren't shy about putting plenty of bacon on it), and the fries were excellent. They'll definitely be on our list to stop in again and try some of the other offerings on their menu. Additional minor bonus: sugarless sodas other than (or rather, "in addition to") "diet cola".

"Buttery-Taste® Spread", fake "maple" syrup, Pasteurize Process Cheese Product...yup, cheap "greasy spoon" diner food. It is, however, GOOD cheap greasy-spoon diner food. For those among us who consider this genre of food to be a guilty pleasure, this is definitely not a bad place to stop.

Very good sushi. After the initial, partial delivery came out quickly the rest came out very slowly - think they may be understaffed. Service was very friendly despite slowness, though. Highly recommended, unless you are in even a little bit of a hurry.
