The iPod is 10 years old this fall and most of us can remember the first time we ever picked one up. The smooth action of the scroll wheel with the slight click as you moved through albums or artists. In 2001, the iPod seemed like the evolution of the music player–less hard drive than box of wonder–but for its first few generations the iPod remained a one-way street. Your computer sent music to the device and the iPod sent it to your ears.

So much has changed with media players in the last decade, but perhaps the most important is the two-way expressways they’ve become. We’re as likely to record a track as listen to one, and the addition of better optics and HD cameras have only expanded the role of the iPod and now the iPhone as a mobile media production studio.

The App Store is teaming with media creation apps, but these are the best of breed.

#4 – GarageBand

Apple re-imagined audio production for the touch interface. GarageBand brings smart instruments to the iPad and the iPhone to support performers of all skill levels. It also packs an 8-track recorder and mixer for editing together an interview or electric guitar solo quickly. When you’re done, the app can export high-quality audio files or bring your tracks into GarageBand back on your Mac for further editing.

#5 – Filterstorm or Filterstorm Pro

The quality of the camera now on the iPhone with the sudden explosion of photo sharing sites have encouraged app developers to move beyond seeing this as a basic camera-phone. Apps like Filterstorm bring together the combination clean interfaces with advanced tools to approximate Photoshop Elements on a mobile platform. The Pro version is iPad only but–combined with the iPad camera connection kit–provides opportunities to get some real work done on the road.

#6 – iMovie

Since video first came to the iPhone on the 3GS, student filmmakers have been exploring ways to shoot music videos and short films on it. Now with the processing power of the iPhone 4, 4GS, and iPad 2, editing and basic visual effects are also possible on a mobile device. Like GarageBand, iMovie allows you to record content directly into the app, bring in DRM-free music from your library, and cut together a movie with basic edits and transitions. When you’re finished, the app makes it easy to upload to YouTube or Facebook, and with video mirroring to play it on a local TV.

#7 – ReelDirector

This is an alternate movie editor compatible with all versions of iOS device. It provides most of the same features now found in iMovie but does allow access to DRM and DRM-free music from your library. Both apps also provide a platform for creating narrated slideshows or digital storytelling projects quickly and easily.
