Features & Capabilities

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.

User Reviews

Reviewers praise Acoustic Picture Transmitter Pro for its groundbreaking ability to encode images into sound with striking spectrogram visuals and entertaining experiments. However, many report stability and compatibility issues across devices, camera/mic access problems, and occasional failure to display received images. Users also ask for more features and formats to broaden its utility. Overall, a unique, educational, and fun tool with significant reliability improvements needed to reach broader consistency.

Pros

Innovative, one-of-a-kind concept of transmitting images via sound with a visual spectrogram.
High-quality, impressive image output and clear visualization during transmission.
Rich interactive capabilities and experimentation (live sound input, frequency controls, ability to deform images with audio).
Educational and entertaining appeal for acoustics enthusiasts and even educators.
Practical sharing/export capability (send image via audio and share the resulting sound file).

Cons

Crashes and instability across multiple devices and iOS versions, affecting reliability.
Camera and microphone access problems (camera won’t open, mic not picking up transmission).
Inconsistent image transmission/display (sometimes fails to receive or show the transduced image).
Notable feature gaps and requests for more capabilities (color data encoding, encryption, additional export formats, saving settings, orientation options).

this app is amazing and almost a way to visualize wifi networks, how ever it could have a few more features. encoding color data or an option to use some form of audio encryption would be cool, to encode and decode audio realtime
