Octave: An RTA for the iPhone

Alex Wiltschko

[ This app is no longer available for download ]

Octave is a real-time spectrum analyzer for the iPhone and iPod Touch that uses time-domain analysis, rather than FFT techniques. Octave follows strict ANSI certifications for sound analysis, found on multi-thousand dollar sound equipment. You can have pro-quality sound analysis on your iOS device for tiny fraction of the cost!

See your sound in detail with up to 1/12th octave bands. Quickly find out peak frequencies with a swipe to access the cursor, and tap-and-hold to freeze the audio with live spectrum averaging (it will turn blue, slow down, and look completely radical).

What's new in version 1.3
NEW:
The most requested feature is finished! Tap and hold to get an average spectrum of the sound around you. Real-time averaging!

COMING IN SOON:
- Saving average curves (some of the UI is finished, but I'm polishing the rest of the experience — it's not quite perfect).
- Pink noise generation
- Mic calibration

Our verdict: Ok
  • + Octave: An RTA for the iPhone is an ok, 3.5-star app.
