Digital Noise: Music and Tech

Amidio makes some heavy-duty musical apps for the iPhone and iPod Touch; I was particularly impressed with StarGuitar, which gives you a virtual guitar with a bunch of preset rhythms, letting songwriters create quick sketches of ideas when they're nowhere near a guitar.

I created a nice vocal loop from the new Beach House single, then dropped it into Pink Floyd's "Astronomy Domine." It took me about five minutes.

On Tuesday, Apple approved a new Amidio app, called TouchDJ, for the iPhone and iPod Touch, and it's both very impressive from a technical standpoint and a heck of a lot of fun. The iPhone can only play one audio track at a time, but TouchDJ essentially fools it into placing two MP3s side by side for simultaneous, real-time manipulation and playback. It's like a two-track digital DJ setup right on your iPhone.

You get a crossfader to control the balance between the two tracks, plus individual controls for each track's volume, pitch/speed (which aren't independent from one another, unfortunately), equalization (three bands), and effects (the built-in real-time effect sounds like a kind of flanger, and there are several lame samples of a low-pitched robot voice, but you can upload your own). Each track is represented by simple waveform images that use a different color for the bass, which helps you match beats more effectively. A tempobend effect, which lets you quickly bend the speed up or down on either track, also helps you get in sync.

The looping functions were most impressive--you can create a cue and loop mark at any point in either track, then return to the cue with the rewind button, move to the loop mark with the fast forward button, or create an endless loop between the two points. All of this is in real time. If you've got an audio splitter, you can even create a separate cue track for your headphones--for example, to set up a loop in your second track while the first one is playing, without exposing your experimentation to your audience--although this requires some serious processing power, and is recommended only for an iPhone 3GS.

I had a quick conversation with Lala co-founder Bill Nguyen this afternoon, and he filled me in on some of the company's plans to expand its presence in Google's new music search feature. Today, when you search for an artist's name, Google uses mathematical algorithms to determine which songs to display--no editor is involved. But eventually, artists will be able to use Lala's platform to ensure that specific content, such as a new song, shows up in the music search results at Google.

An example of Google's embedded Lala player, which appears on a search for "Joy Division."

Artists and labels will also be able to work with Lala to sell products other than MP3 downloads through Google's search results. For example, Lala is working on a deal with Rhino Records where users will be able to buy vinyl Joy Division records directly from Lala. Eventually, the offer will appear within Google search results on queries like "Joy Division" as well.

For Rhino, this kind of deal is a no-brainer: they're suddenly getting free placement for a relatively high-priced physical product in Google's search results. But it's also beneficial to users: if they buy through Lala, not only will they get the records, but they'll also get all the digital tracks on the LP immediately added to their Lala locker, which lets them listen to those tracks from any PC with an Internet connection. (I've been using Lala's excellent locker service for about a year. Basically, it uploads your entire music collection to the Web, then lets you add additional songs for only $0.10 apiece.) And if users like the deal, then they're more likely to use Google for future music searches. Wins all around.

And that gets me to the most exciting Lala announcement of all: The company has submitted its iPhone app to Apple and hopes to have it approved some time in November. The app will allow users to stream any song in their online Lala locker to their iPhone, over both 3G and Wi-Fi connections. Conceptually, it's similar to iPhone apps from Spotify (in Europe) and Rhapsody, but without the subscription fee; any song you've uploaded to your music locker will be available on your iPhone. And of course, you'll still be able to buy streaming-only versions of new songs for $0.10 a piece. (Lala might charge something like $5 for the app itself, but the company hasn't decided.) I'm getting an early look some time in the next few days. I'll try it and report back on how it works.

If you listen to music on your iPhone or iPod Touch while you're driving, you probably don't exercise much control over your playlist--skipping and pausing songs without looking down at the screen is almost impossible. Fortunately, there are apps for that.

One of many background and font choices that come with SongVoo.

SongVoo, which released version 1.1 last week, is my latest discovery in this realm. It's similar to PlaySafe in that it places a skin on top of your iPhone's music player, superimposing the artist, song, and album name in large letters, and lets you control music playback with simple hand gestures that don't require you to look at the screen--in the case of SongVoo, you touch anywhere on the screen to pause, touch twice to fast-forward to the next song, and touch three times to reverse.

It has several advantages over PlaySafe, however. With PlaySafe, you have to choose songs or playlists and add them to the app before you can start using it, and it can take a little while for PlaySafe to index them. With SongVoo, this process is much more efficient--it added all 800-plus songs on my iPhone in under five seconds.

Alternately, you can begin playing your music from the normal iPod music app and then open SongVoo to superimpose SongVoo's skin on top of it. SongVoo also offers tons of backgrounds and fonts, and lets you switch among them simply by shaking the device. There are also smaller finger-buttons for setting your playlist to shuffle, to loop songs or the entire playlist, and to see detailed song information.

Version 1.1 of the app adds a couple of features that seem geared toward the attention-deficit-disorder set. You can preset the app to skip the intro and/or outro of every song (you set it by time length, such as 25 seconds), and post updates to your Facebook page simply by drawing a "W" on the screen with your finger. (By default, it posts "I am dancing to..." and the name of the song and artist, but you can change the message to something cheekier if you like.) Useful, fun, and only $0.99.

Back in the dark ages before Internet access, staying on top of the coolest new music required some work. You could read about new bands in magazines and newsletters--the more obscure the better--but most music fans had a few people they trusted to be their personal music experts. Record store clerks, friends in bands, and people in the local art scene all competed to be up on the latest new sounds coming out of Austin or Detroit or Seattle, and the rest of us reaped the benefits of this competition.

Miracle Fortress, one of the recommended albums from a real live record store owner, Sonic Boom's Jason Hughes.

Panel, a new Web site and associated $2.99 app for iPhone and iPod Touch, updates this old world of trusted experts for the new world of on-demand digital music. Created by Los Angeles record producer Darius Fong, Panel will enlist a new expert every couple of weeks to recommend two recent favorite albums. The iPhone app lets you stream these albums in their entirety or on a song-by-song basis, and provides information about the album and panelist (this information--but not the music--is also available on the Web site). If you want to buy it, the iPhone app has a link to iTunes, and the Web site links to both iTunes and Amazon's MP3 store. You can even share your recommendations via your Facebook update status or Twitter feed, allowing you to pretend that you discovered this obscure gem all by yourself.

Panel's first expert is Jason Hughes, the owner of one of my favorite Seattle record stores, Sonic Boom. Future panelists, according to the company, will include Justin Gage, who created the Aquarium Drunkard music blog and XM/Sirius radio show, producer and musician Matt Bayles, who used to be part of Seattle band Minus the Bear, and bronze sculptor Peter Harper, who also runs an online Musician of the Month contest from his Web site and happens to be Ben Harper's brother.

Yesterday, I blogged about how the forthcoming Droid won't be an iPhone killer because it lacks the simple sync interface provided by the iTunes desktop application. I neglected to mention an excellent application called DoubleTwist, which offers the easy sync experience of iTunes for a much wider variety of devices, including all the Android phones currently on the market, most BlackBerrys, Sony's PlayStation Portable, and a huge range of other non-Apple products--as well as the iPod and iPhone, if you're so inclined.

DoubleTwist has a large orange Sync button in exactly the same location as iTunes.

Created in part by Jon Lech Johansen (aka DVD Jon), who's best known for helping crack the encryption system used on video DVDs, DoubleTwist is available as a free download for both Windows (including Windows 7) and Mac. Plug in any supported device, and DoubleTwist immediately recognizes it, lets you choose content to sync (pictures, videos, and either all your music or select iTunes playlists), and then begins syncing that data with a single click of a button. It also boasts integration with Amazon's MP3 store, giving you a rough equivalent to the iTunes Store. DoubleTwist also has an interesting sharing feature that lets you select any piece of content from within the program and e-mail a link to a streaming version of that content to your friends (the content itself is stored on DoubleTwist's servers). This feature integrates with e-mail address books from Gmail and Yahoo Mail if you want to spread that latest remix far and wide.

DoubleTwist co-founder Monique Farantzos e-mailed me specifically about yesterday's post, so it's a safe bet that the application will support Droid. More to the point, as phone makers continue to miss the importance of iTunes, DoubleTwist is essentially becoming iTunes for those devices. There's one crucial difference: Apple either ships a disc with iTunes with its devices, or prompts you to download iTunes when you install them. For these other phones, you have to know where and how to get DoubleTwist.

Apple outstripped Wall Street's expectations for the quarter ended September 30, and while the blowout quarter was mostly thanks to higher-than-expected Mac sales, the company also sold a record 7.4 million iPhones. But a lot of commentators think that the iPhone is finally going to meet its match with Droid.

You don't need an instruction manual to figure out how to get music onto your iPhone.

Announced this weekend by Verizon in a cheeky TV commercial, the Droid is a Motorola phone running Google's Android 2.0 operating system. The advertisement notes that the Droid will do things that the iPhone won't, like take pictures in the dark and run simultaneous apps (apparently playing music in the background, as the iPhone can do, doesn't count), and touts its open development process (a head-scratcher for non-techies, but it could mean more apps than the iPhone, someday). The first preview I've seen, from Boy Genius Report, was also positive. People are excited, and for good reason--competition drives innovation, which is good for consumers.

But here's the thing: one reason for the runaway success of the iPhone--and one of the reasons why Apple still continues to sell more than 10 million iPods per quarter--is iTunes. Not so much the store, although that's an important component, but the software. Of course there are plenty of other applications out there that help you rip CDs and organize your digital music collection. And there are plenty of other sources for online music. But the real strength of iTunes is in the sync process--you plug your iPhone in, iTunes opens up automatically and recognizes it. Hit the large "Sync" button and it automatically loads your music (and video, and apps, and anything else you choose) onto it. (With some devices, depending on your settings, you don't even need to hit "Sync.") That's the simple, consumer-friendly, end-to-end experience that Apple figured out first.

Contrast that with the multi-step process required to transfer music from a Windows PC to the first Android phone that was available in the U.S., last year's G1. Amazon provided over-the-air MP3 downloads for that phone, giving it a rough equivalent to the over-the-air version of the iTunes store, but let's face it: most digital music is not purchased, but is ripped from a CD or comes from some other source (legal or not).

Verizon, Motorola, and Google haven't said much about music for the Droid. Maybe they still have a musical trick or two up their collective sleeves. But without some sort of equivalent to the iTunes desktop application, the Droid may be a great phone, but it won't be a great music phone.

The free ConcertVault iPhone app gives you streaming access to hundreds of live recordings.

Wolfgang's Vault is an online archive containing hundreds of high-quality concert recordings, mostly from big classic-rock artists like The Who and U2, but with a few newer artists, such as The Walkmen, thrown in as well. (Here's a complete list of performers whose recordings are available on the service.)

Last month, Wolfgang released an updated version of its much-lauded free iPhone application, Concert Vault, which gives you access to these amazing shows directly from your iPhone or iPod Touch.

The update adds a couple minor features, including a list of featured concerts--helpful for keeping track of shows that have been recently added to the vault--and fixes some reported problems with stuttering and stalling.

I've been listening to the Who's 1973 performances of "Quadrophenia" over a 3G connection for the last half hour, and so far, the app--and the band--are both performing flawlessly. This is a worthy update to a must-have download for live music fans.

JamBase, one of the first and certainly most famous online concert-listing services, released its free iPhone app last October. It was a simple affair: you entered your ZIP code and the app returned a list of live music shows in your area over the next few days. If you had a list of favorite artists stored at the JamBase Web site, it would track those artists for you. Since then, competing apps like Bandloop and iConcertCal have upped the ante with more sophisticated interfaces and GPS targeting, which lets them find nearby shows without forcing you to enter any data.

JamBase's updated iPhone app lets you track favorite artists and add their shows to your JamBase calendar.

Version 2 of the JamBase iPhone app, which was released on Thursday, brings JamBase up to speed with its own GPS feature--you don't have to enter a ZIP code unless you're searching for results in another location. You can limit search results to shows within a certain distance of your current location, or within the city limits of your town. Plus, it's much better integrated with the JamBase site: you can sign up for a free JamBase account right from the app, then add favorite bands to keep track of and even add particular shows to your calendar; all changes are synced between the iPhone app and the JamBase site.

The one place it lags is in synchronization with other apps. Here, I prefer iConcertCal because it uses your iTunes library to build a list of artists you're interested in. JamBase makes you enter them manually. iConcertCal's app has a "Listen" feature that launches the iTunes Mobile app to let you listen to 30-second samples and, if you like them, buy the tracks. JamBase features audio samples from LaLa on its Web site, but no equivalent on the iPhone app.

Agile Partners, best known for creating an exceptionally useful $9.99 iPhone application called Guitar Toolkit that packs in a guitar tuner, a metronome, and fantastically detailed chord and scale charts, on Monday released its first follow-up app.

Tab Toolkit, also available via Apple's App Store for $9.99, enables users to read and listen to real-time synthesized versions of guitar tablature charts on their iPhone or iPod Touch.

Here's Kirk Hammett's guitar solo from "Master of Puppets," displayed in tablature and regular notation on an iPhone with Tab Toolkit. Hit "play," and it'll scroll by in (very fast) real time, with a synthesized version playing through the headphones.

Tab Toolkit won't have as large an audience as Guitar Toolkit, which is immediately useful to players of all levels, as it assumes that you have (or can get) tab charts--and that you know how to read them. But if you're a serious guitarist, $9.99 is a fair deal for a very sophisticated app that performs well--no freezes or stutters, as I've experienced with some other music-oriented apps. (If you're just learning about tablature, the $2.99 iPractice is probably a better first download.)

So where do you get tab files? If you're a songwriter, you can use Power Tab Editor (freeware, Windows-only) or Guitar Pro ($59, for Macs and Windows PCs) to create your own. There are also online libraries of tab files for popular songs and artists--GProTab has a particularly extensive collection of Guitar Pro files--though copyright holders periodically crack down on these sites, which generally operate outside their approval.

Once you have some tab files on your computer, Tab Toolkit lets you transfer them to your iPhone directly over your home wireless network. It also includes an embedded version of Safari so you can download tabs directly from the Web. Tab Toolkit does support PDF and rich-text tabs, but you get the most results if you use PowerTab or Guitar Pro files.

At last, once you have some PowerTab or Guitar Pro files on your iPhone, the fun begins. Tab Toolkit scrolls through the song at the correct tempo, displaying both traditional and tab notation, with a metronome and synthesized version of the instrument to keep you on target. It fully supports multitrack tabs for the same song--for example, I was able to download all three guitar parts, bass, and drums for Metallica's "Master of Puppets," and follow through each individually--and you can stop the automated playback and scroll through the chart manually to learn particularly tricky parts like Kirk Hammett's guitar solo. You can display either a guitar fretboard or piano keyboard on the screen to help you with fingering, and can even flip the guitar upside-down if you're a lefty.
