Audible Ink

By Pete Schwamb

Open iTunes to buy and download apps.


Audible Ink encodes imagery into sound. Take any image from your photo library and play it over your iPhone speakers or iPod headset.

This tool is similar to those that professional musicians, like Aphex Twin, use to embed imagery into their music. The vertical axis maps to frequency, and pixel brightness maps to volume, so bright pixels near the bottom will produce lower tones, and those near the top will be near ultrasound.

Many images will sound roughly like static, though with a spectrogram analyzer, like Spectrogram for the iPhone, you'll be able to clearly see your original picture. To produce clear tones, use images with thin, white lines.

This app also allows you to perform image processing algorithms on your photos such as edge detection and contrast stretching to improve the audio output and picture quality in a spectrogram.

Sound Imaging

Not quite sure what to make of this app. It basically scans the image and converts it to sound, as the description suggests. Although I have only used photographs, to me, it just sounds like static. I expect this would change if I were to use imaging with stronger colours. It does have certain filters to make the image better for the application, such as edge detect and contrast. I prefer the edge detect option as it tends to lead to a better sound. So, there you go. Have fun.


Useless as there is no way to save the sound! A waste of 69p - deleted it!
