Audio recordings of long meetings and classes are only marginally useful. Wouldn't it be nice if you could listen just to the parts related to specific sections of your written notes? It turns out there's an app for that. In fact, in this mini-roundup I review three iPad apps that promise to make taking and using notes a lot less painful than it used to be.
I've been using AudioNote and SoundNote for the last year. I recently received a free review copy of Audiolio. All three apps do a good job of synchronizing audio recordings with text. Sound quality is not great--but you can blame the iPad's microphone and the difficulty most of us have getting it close to speakers for that. AudioNote provides the best mix of an intuitive graphical interface, useful features such as words highlighted during playback, and easy exports of your synchronized audio and text. Its only minor shortcoming for Windows users is that it uses CAF--Apple's Core Audio Format--as its export format.
Check out the features table below for an overview, and read on for reviews.
|Graphical interface metaphor||Blocks of text||Lined notepaper||Lined notepaper|
|Audio file format||.M4A (MPEG-4)||.CAF (Apple Core Audio Format)||.M4A (MPEG-4)|
|Audio export||Dropbox, email, iTunes file sharing||Email, Wi-Fi, iTunes file sharing||Dropbox for linked email attachments, email, Wi-Fi|
|Text export||PDF, text file, or Audiolio's own file format||PDF, text file||PDF, text file|
|Arbitrary playback start points||Yes||Yes||Yes|
|Synchronized word highlighted during playback||No||Yes||No|
Audiolio offers plenty of ways to disseminate your notes. The MPEG-4 (.MP4) audio files it creates can be played with almost any audio player software including Microsoft's own Windows Media Player and Zune. You can share captured text and audio using email or syncing with iTunes. Audiolio is the only one of the three apps that can send the text and audio files directly to a Dropbox account. Unfortunately, it's also the only one that doesn't let you draw pictures as part of your hand-entered notes.
You can share captured text in one of three formats: plain text, PDF, or Audiolio's own proprietary format. The last option would come in handy for sharing your notes with another Audiolio user. Unfortunately, the plain text option stores what you wrote as one long string of text.
The status bar at the top changes from gray to red when the app is recording audio at the same time it's recording your typing. A nearby button conveniently lets you pause the audio recording while you continue to type or draw. You can include a line drawing by tapping the pencil icon on the right side of the status bar.
AudioNote can export text and audio via email, iTunes file sharing, or Wi-Fi. Typed text can be exported into a plain text file or a PDF. AudioNote saves audio files in Apple's Core Audio File (CAF) format--that means Windows users will need to install Apple QuickTime or some other media player that can play CAF files to listen to them. A version of AudioNote for Macs is also available--but you can't share notes between your Mac and iPad AudioNote apps, unfortunately.
Sharing is limited to email and Wi-Fi. However, when you email your document, SoundNote does give you the nice option of sending just the visual part, or a combination of text with audio. Like AudioNote, SoundNote can export to text or PDF. But it saves audio in the MPEG-4 format, not CAF, so Windows users don't have to install any extra software to listen.
On the downside, SoundNote's audio export scheme is not as cohesive as Audiolio's or AudioNote's. If audio was recorded in segments in a single note, the audio is split into multiple files. If your recording session contains lots of pauses, dealing with all the individual files could be a pain.
All three of these apps would be much more valuable if there were an easy way to use the files on a desktop PC or Mac. For instance, I'd like to be able to use my iPad at a meeting, then transport the recording to my Mac for listening to the audio while cutting and pasting from the notes into other apps.
But what they do is valuable enough for iPad users even without this capability. Professionals, students, journalists, and anyone else who needs an easier way to record and play back meetings or events will find one of these apps very handy.
