With APT you can transmit and receive images acoustically. To do this each column of the selected gets transformed by a Fast Fourier Transform and outputed through iPhones speaker. On the receiving iOS-device the received audio is visualized by a spectrogram and the incoming images get visible. You can use this app for example to transmit images very easily over a phone or to put images in every kind of audio recording.
The pro-version has the additional features of choosing between two coding methods, choosing between linear and logarithmic frequency scale and the ability of sending the resulting audio as email. Also, the pro-version isn't ad-supported.

I really hope this app still has support. I don’t know if there are any others out there like this. I especially like the frequency selection so I don’t blow ears out. But I have some cool ideas for this. I’ve been messing around with a lot of random sounds to just to see what comes out of it.
Amazing and works great!
It is uncanny how good the image quality is, and a little bit eerie, although highly scientific in actuality.
Camera Malfunction(?) Reloaded /iOS 13
Would have liked to give this a great review, but the only function working was sending a picture from library and the audio play. The camera function did not work, no picture black screen, I reloaded reinstalled, the camera function showed now a sunshine or lighten brightened which stayed in black screen my guess is that the picture facing function pivot button doesn’t work.
A Suggestion: I would prefer it allow the person to permission the camera as they have set, not use the program screen to do that part. In doing so, perhaps we can bypass this problem?
Please message me, if there is a way to fix this problem. Thank you for the trial application. I once used a very good model to make spectrogram, in same app. We can also send and receive, but the image it made, we could simply change the pivot screen on our camera setting for selfie example shot and save to our library.
It’s 1963 again!!!
This technology was used by NASAs satellites to transmit images, taken in space, back to earth.
The principle behind that system is used in this phone app. Very cool. I now use it to broadcast images through my radio set to radio listeners across the country! Fun fun!
App no longer works
App no longer works on XR
This app broke since last update
My cam won’t open up and the mic doesn’t pick up the transmission. Please fix. I’ve had this app since my iphone3gs and have bought it 3 times . Works well on my legacy devices. This device is a 6s plus.
Doesn’t work
Doesn’t receive image
Please update this amazing app
This app is Amazing. Please, please update it. Such a wonderful tool should come standard with computers and phones. Sharing files crashes the app, and the ability to switch between portrait and landscape would be a wonderful addition.
Can you add more features?
This app is AWESOME! I used to have to do this on my desktop, cutting, pasting, and converting files through several pieces of software.
It would be helpful if the app had a few additional features:
1. The option to import an image OR view live sound (the microphone). Right now, it picks up background noise (coughing, cars driving by), which adds unwanted frequencies to the generated sound.
2. The option to output the audio file in different formats (m4a, mp3, WAV). I know different compression algorithms would also change the image, but having a smaller file size would help me email these to myself.
If you could add even more features, it would be even better!
3. The ability to raise or lower the threshold/Hz/limit of the sound so the image could be taller/shorter. Right now some images get stretched strangely.
4. The option to share the output audio file to a different app, rather than only mailing it.
Thank you, again, for creating this!
Great app! Works super well
This app is great it has many things you can’t do with other paid spectrogram apps, and it lets you put pictures into your sound then send it to people. Really wished this app got more attention, it really deserves it.
