Back when we looked at Radar, a photosharing site with an accompanying iPhone app, I mentioned that while Twitter had monopolized the "text exporting" function from your iPhone, there would be a slew of companies to try and grab the rest of the media you want to broadcast. Radar, I said, wanted to be the photo app. And AudioBoo, it appears, wants to be the audio app (we've yet to see a strong video contender pop up with the 3GS, though YouTube is certainly serving for now).

I've been using AudioBoo (iTunes link) for a few weeks now, and I have to say, it definitely does what it says on the box: after a short signup session and the installation of the app to your iPhone, you can record and upload (and almost more interesting, listen back to others') audio quickly and easily.

You hit record, can talk for a while (i haven't hit a limit yet, though three minutes is what I originally heard, and that tends to be about right for these little mini-podcasts), then hit stop and upload, add a picture, title, and tags, and a few minutes later, your audio is right there on the web for everyone to hear. I've used it on my EDGE phone and my friend's 3G, and I have to say the experience is better on the 3G -- the upload speeds are much better (I generally have to wait on my iPhone until I get on Wi-Fi to upload the audio), and to my ears, the audio sounds better. Here's a recording I made at a Cubs game on my 1G with a few friends, and a recording my friend made on his 3G at a restaurant. Edge works, obviously, but the 3G seems to work better.

WorldVoice Radio [iTunes link] is a cool little iPhone app that may help do for podcasting what Twitter did for web publishing -- make it easy to send out short, frequent messages. Of course, there's a difference, since WorldVoice Radio does this by letting you publish short podcasts from your iPhone. If you've used Utterli or Audioboo, you have the general idea.

The app, which was created by Kai Cherry and RnSK Softronics, has just arrived in the App Store. Kai is an occasional guest on the TUAW Talkcast, and he asked a few of the TUAW bloggers to join his beta testing team for WorldVoice Radio. (In the unlikely case that you're not familiar with the concept of beta testing, it's about getting a group of users together to make sure that an app is bug-free and functional prior to going to market.) Follow along as I give you a first look at this intriguing app, and as I beta-test WorldVoice Radio.

We've mentioned it before (via Laurie and Scott's posts back in ought-six) but it's worth a Friday Favorite: if you're looking for a free, cross-platform tool that does one thing to audio and does it very very well, you need to download The Levelator today.

The Levelator is offered by The Conversations Network as a single-purpose tool: it takes uncompressed audio (WAV or AIFF files) and performs a small miracle. The file is leveled to a uniform loudness level, even if varying parts are recorded with different microphones, audio settings, or even in diverse corners of the world (if you've ever tried to record a podcast over Skype, you know what I'm talking about). While many audio apps have normalization or 'leveling' functions, in my admittedly amateur audio experience I haven't heard anything like The Levelator; those with more savvy in this area tell me that the output is akin to what you would get with a human engineer 'riding the meters' to adjust the sound dynamically as it varies.

The really nice thing about The Levelator -- and this is an odd thing to say about a Mac application -- is that it has, for all practical purposes, no controls. Drop a file on it, wait an appropriate amount of time and watch the blinking lights, then take your output file and continue on your merry way; the final file will simply sound way better than the original did. It's made my life much easier in editing the TUAW Talkcast, and if you have any hand in producing spoken-word audio it might do the same for you.

The Levelator is a free 48 MB Universal Binary download, and will work on either 10.4 or 10.5, as well as Windows and Linux. Enjoy!

Humble Daisy's ProfCast is a well-respected tool for turning PowerPoint and Keynote slideshows into podcasts, among many other features (including the ability to record live presentations). The software was recently updated to version 2.3.0 and if you haven't been motivated to try it before, it is definitely worth a look now.

Humble Daisy is currently offering the software for 75% off its retail price from today until January 24 to celebrate the Mac's 25th birthday. ProfCast normally retails for $59.95USD, and education discounts are available, but the sale brings the price down to $14.99. ProfCast requires OS X 10.4 and later.

And for the confused, myself included, ProfCast's Web site does say that the discount is for 25% off rather than 75%. However, by clicking on the coupon for a single-seat license, you can see that the price really is $14.99.

Educators and professionals who need to record and podcast lectures often turn to Humble Daisy's ProfCast, a tool for adding enhancements to PowerPoint or Keynote slideshows to create powerful podcasts.

ProfCast today received a major update to version 2.3. The original app allows recording of live presentations, syncing slides with an audio track, and full RSS feed generation and publishing support. The new version incorporates several improvements, the most significant being support for PowerPoint 2008.

The app now automatically detects whether Keynote or PowerPoint is being used for a presentation, and then begins the process of recording and publishing the lecture with all slide timing and voice narration.

Humble Daisy also killed a number of bugs from the previous version of ProfCast, and version 2.3.0 is a free upgrade to existing owners of the application. The program is $59.95 for first-time buyers, and educational discounts are available. ProfCast can be purchased from the online store.

A few months ago, I started recording a podcast with some friends. At that time, our process was to gather everyone into one Skype call and record the session with WireTap Studio. That worked reasonably well, but there were a few problems.

The quality of the end result was dependent on everyone's Skype connection. Throw in a bad rainstorm, a large download or an iffy wi-fi connection and quality suffered. The other issue was people talking over each other. Even the most disciplined podcasters do it occasionally. Since the raw audio was a single track, editing the overtalking out of the final show was difficult, if not impossible.

A few episodes into it, we read Dan Benjamin's tips on recording a podcast with participants in multiple locations. He and John Gruber use a time-tested method called a "double-ender" when recording The Talk Show. As they talk via Skype, John and Dan record their own audio locally, and those two files are edited together as separate tracks. We've adopted a similar method using GarageBand, and it's been working wonderfully. Read on for details on our setup.

Do so on TalkShoe by using the shiny browser-only client; or you can also use the classic TalkShoe Pro Java client that we all know and love. For the web UI, just click the "TalkShoe Web" button on our profile page at 10 pm Sunday. You can also listen in on the Talkshoe page or call in on regular phone or VOIP lines: dial (724) 444-7444 and enter our talkcast ID, 45077 -- during the call, you can request to talk by keying in *-8. Talk with you then!

Recording support for the TUAW Talkcast provided by Ecamm Network's CallRecorder for Skype.

Our buddies over at sister blog Download Squad gave us a heads-up this morning about a new release of Audacity, the open source, cross-platform audio recording / editing application.

Audacity 1.3.6 (Beta) for Mac has new features added by students during the Google Summer of Code 2008:

• Support of WMA, M4A, and AC3 file formats
• Import of audio from video files
• On-demand loading of uncompressed files, eliminating the wait before files can be edited
• Linked audio and label tracks, so labels move with their corresponding audio when cutting, pasting, or changing speed or tempo
• A hierarchical plug-in grouping for built-in plugins

Experimental features include:

• Sound activated recording
• MIDI file import, edit, and export

As always, Audacity is free. Click here to head over to the download page, and remember that this is betaware.

Those of you who like to use your iSight cameras to record and upload video to YouTube or other video sharing Web sites will be happy to know that Dream Apps has released version 2.2 of Dream Capture.

Dream Capture is designed especially for both internal and external iSight cameras, although it works with other cameras as well. The 2.2 release now features auto-focusing technology derived from Apple's Shake software, metadata support for iTunes 8 imports, and H.264 video encoding.

Dream Apps also added their audio compression technology, DreamSync, to Dream Capture 2.2. A new audio-only recording mode is available for those who wish to use Dream Capture to record audio podcasts or lectures.

This is a free update for existing Dream Capture owners. Interested readers can download a trial version of Dream Capture (click begins download), and then purchase the application for US$9.95 if it fits your needs. A Mac running OS X 10.4 or later is required.

In the iTunes 8 new features listing, a couple of tweaks may have been overlooked. Podcast subscribers have long yearned for more granular control over downloading and retention in iTunes -- "keep three episodes" might be great for Wait Wait, Don't Tell Me or Mac OS Ken, but what about Coverville or You Look Nice Today? You'd surely want to keep those & other awesome 'casts in perpetuity, and there are some podcasts that are so large you want to cull them after one download.

Now, iTunes 8 lets you apply retention policies on a podcast-by-podcast basis. Select the podcast in the list and click the "Settings" button at the bottom of the window, then UNcheck the "Use Default Settings" box to enable custom prefs for that particular show. Dee-lightful! Unfortunately, podcast-to-iPod sync settings are still one for all and all for one, but this is a step in the right direction.

Update: Comments below (and a visit to the Wayback Machine) have confirmed that the territorial clause in the iTunes store TOS is not a new addition with v8, but has in fact been in place for quite some time. It's interesting that it only came up as a topic of discussion now -- perhaps because everyone was forced to reaccept the TOS with the new version, and read it a bit more carefully? It's also looking like the clause was displayed front and center on the new TOS acceptance screen; this degree of prominence seems to be new, and probably attracted attention to the pre-existing restriction. In any case, our apologies for the error.

Speaking of minor changes that might have major implications, a number of readers have expressed concern about something that Robert originally pointed out in his rundown of iTunes 8: that the iTunes store terms of service (long a source of controversy in Europe) now include have long included a clause restricting use to the geographic area where the user's account is established. In the US the rule reads:

10. Territory. The Service is available only in the United States. You agree not to use or attempt to use the Service from outside of the available territory, and that Apple may use technologies to verify your compliance.

There are several classes of users who might run afoul of this restriction: travelers who shop in their home stores while venturing abroad, for example, would technically be in violation... but our suspicion is that these casual, intermittent border-busters are not what Rule 10 is about. Instead, any enforcement of this restriction is likely to be aimed at users who live in one country and establish an iTunes store account in another -- allowing them to buy TV shows or movies that may not be available yet (or ever) in their localities.

Certainly the content providers who sell their wares through iTunes may choose not to sell their programs to a particular region at a particular time; that's their prerogative. It seems somewhat myopic, however, to think that enforcing restrictions by geography in the iTunes store will have any effect other than to drive revenue and customers from the quasi-legal market firmly into the rip-and-download underground.

Thanks to Eric & Mark

Take Control Books has just published the second edition of Andy Affleck's popular Take Control of Podcasting on the Mac ebook. Anyone interested in getting started with podcasting or improving the quality of their current podcasts should read this ebook.

Take Control of Podcasting on the Mac: Second Edition adds coverage of two widely-used Mac podcasting applications, WireTap Studio and Übercaster, with information on recording and editing podcasts with these two apps. Andy also updated the ebook to discuss podcasting with GarageBand 4, and dropped his coverage of Audacity as a podcasting tool. Want to hear how good your podcasts can sound? Listen to Andy's promo.

As with all Take Control titles, the $10 ebook will be updated regularly and is available for immediate download from the Take Control website. The ebook includes a coupon code good for up to $14 off the price of Rogue Amoeba's Audio Hijack Pro and Fission, so if you're in the market for both of those products you essentially get the ebook for free.

In the interest of full disclosure, I have written two Take Control ebooks.

In the Mac audio software market, Ambrosia's WireTap Studio made a splash last year when it launched, offering lossless capture and audio editing with a fresh interface (and competing with incumbent heavyweight Audio Hijack Pro from Rogue Amoeba). Although it aimed at being an end-to-end solution for basic podcasting and audio production needs, the limitations of the built-in editor meant that high-end and pro users still needed to export from WTS to complete a project elsewhere. Since most pros end up in another editing environment anyway, why not have the underlying capture engine from WTS available to any recording application, and turn your Mac into a virtual patch bay?

That's the concept behind Ambrosia's new pro-level (and pro-priced at $129US) capture tool, WireTap Anywhere. Rather than the two-channel recording options of WTS, with the WireTap Anywhere preference pane you can route and mix multiple audio sources and deliver them to the recording application of your choice. Want Skype, iTunes and QuickTime sources all to end up in Peak or GarageBand? WTA has your back. You can check out several demo movies at Ambrosia's site or download the 13MB demo.

I've experimented with several combinations of recording software and application audio capture tools (Soundflower, Übercaster, Call Recorder, Audacity and AHP among them) and I've yet to find the perfect setup that allows me to combine live audio chat from Skype with music or sound effects played in QuickTime or iTunes, all audible to the remote call participants while being recorded cleanly and latency-free on my end; Übercaster comes awfully close, but the current 1.5.5 version still has issues with Skype dropouts. I'm looking forward to giving WTA a test run to see if it can meet the challenge.

One thing I'm sure a lot of iPhone fans were upset about this week was the lack of an announcement of video broadcasting capability in the 3G iPhone. I mean, OMG, how else are we supposed to make obsessive fan videos of Britney Spears?!

Don't worry, the brilliant folks at Flixwagon are demonstrating live vidcasts from a jailbroken iPhone and are apparently working towards a true iPhone app that will work "as long as your battery lasts."

TV networks? Who needs 'em! We'll make our own entertainment.

Thanks to Chris Albrecht at NewTeeVee.com for the tip!

Just a scant four days ago Dave pointed us towards Apple's new Keynotes Podcast. Now, as if this were planned somehow, Apple has updated that very same podcast [iTunes link] with the video of yesterday's Keynote by Steve Jobs.

The podcast clocks in at 1.18 gigs, but that is a small price to pay for all that iPhone 3G goodness.

Thanks to everyone who sent this in.

We use Skype for the TUAW Talkcast and recently, our host and podcasting guru (OK, not guru, but he is the host and we like him), Michael Rose, has been looking at possibly using Ecamm's Call Recorder 2 plugin as an option for recording our weekly talkcasts. I actually have used it to record both audio and video chat for the Squadcast and really think that it is a fantastic, fantastic add-on.

For anyone unfamiliar, Call Recorder is a great little tool that adds a recording window to Skype. This makes it easy to record incoming and outgoing calls (audio and video). The files are saved in the QuickTime format and they can be converted to MP3 or split into separate tracks.

With the release of the latest version of Skype for the Mac, Ecamm has updated Call Recorder as well. In addition to the latest Skype compatibility, Call Recorder 2.3 also includes a new two-track video recording option (so that you can have a separate stream from each side of the conversation) and enhanced video recording quality.

Call Recorder 2 is $14.95 (for $7 more, you can also get Conference Recorder, which adds the same functionality to iChat, and unlike the built in iChat recorder, doesn't require both users to have Leopard) and a free demo is available if you want to try out the tool.

If you want a simple, hassle free way to record Skype conversations, give Call Recorder a shot!
