FFT


Finally, Android has a professional-level RTA with mic calibration! We gave our app to sound engineers around the world to test. Here's what they said:

"Simple, Fast, Accurate. The best FFT application I have found for Android devices. After a simple calibration process it beats many PC based programs. Custom color make it visible in the sunlight, and low level evening light. Just sit it on you console and see trends as they develop before they become problems."
Keith Finch

"I love this program. I beta-tested mac foh for 3 years and it was hands down the best I ever saw. This app echoes those same feelings. Fast response and clean graphics. Its amazing how much power and information you can hold in your hand with this program. It allows me to be mobile and monitor system performance at various locations without lugging around my laptop or iPad."

ROAD READY
FFT is a real-time analyzer (RTA) meant for professional use. Geared toward use in the hectic, time-critical environments encountered in live sound, this app is designed to not slow you down. Even with all the features packed in, going to the Settings menu is a rarity - most things are accessible from menus on the main screen. You'll never miss a moment, especially since it's built on the lightning-fast speed of OpenGL graphics and native code.

ROAD TESTED
We don't release a version of FFT without extensive testing from a group of real sound engineers that work shows every day. This is an app you can rely on, and it's good for any application, whether in audio, machinery, or any of the hundreds of other things RTA's are used for every day. And, with Android Market's refund window along with our commitment to fix any bugs you report, you can rest assured that you aren't wasting any money.

REAL MICROPHONE CALIBRATION
FFT doesn't use supposed "auto-calibrate" features that make (usually false) assumptions about what's actually going into your microphone. Get a true calibration of your phone's microphone using a calibrated SPL meter with flat weighting and the built-in tone generator. Define up to 80 points to set the calibration curve. A guide is included right in the app.

THE TOOLS YOU NEED
Take and name snapshots of the graph, and display several of them or overlay them with live data later to compare. Find feedback immediately with the peak finder, or monitor a specific frequency or two with frequency markers. Use whatever kind of averaging scheme fits your purposes best - featuring exponentially weighted averaging and unweighted averaging with configurable times. If you want a good overall trace of what's going into the microphone over time, turn on infinite averaging. It's all included in the app.

Features:
• Logarithmic or Linear scale
• Fast freeze button
• Averaging: exponential, flat, and infinite
• Peak Hold, configurable
• Peak frequency finder (full range or visible only)
• Frequency markers
• Snapshots: creating, viewing, and overlaying them
• User-configurable microphone calibration
• Configure FFT Size and Window type (Size up to 16384; 7 window types supported)
• Full control of app colors
• Pinch-to-zoom, one-finger panning and zooming
• Smooth, immediate response to touch
• Continuously updates - never choppy
• And more…

Droid RAZR Users: We are happy to announce full support for Droid RAZR and equivalent models. A workaround for the device's audio issues is available in version 1.1 and above. Please contact us if you have any issues.

Never worked Upon first opening the app on my Note it brought me straight to an error report screen and had done nothing else for me. Basically threw away 10 dollars.

Great while it lasted I had this app installed for years and then one day it stopped working. It seems like it is trying to phone home and then shuts down. I paid close to$10 dollars for the app and while it was working I gave it a 5 star. I've sent 4 or 5 emails to support to no avail. Hence the one star. They claim a commitment to service or a refund but I've seen neither.

Very responsive, pretty accurate even uncalibrated. Spike at 10k is curious, maybe from phone ad conversion? UPDATE - labels broken (no text) on Lollipop (Android 5.0.1) worked before on KitKat (4.4.4) HTC One M8 please fix

Maybe really good If this app worked, then it would be really great I guess. Just that text does not display at all on my HTC One M8. So there are empty buttons that I can press, and no axis labels.
