Now with logarithmic scale

Visualize audio with this handy tool.

It displays the frequencies of sound around you over time. The horizontal axis is time, the vertical is frequency, and the intensity of frequencies is shown using pretty shades of red.

Use it to:

Perfect your singing voice
Analyze the call of animals
Identify and locate annoying sounds around your house
Learn about the world of frequency analysis

I hope you enjoy this handy little tool!

Love it

EASILY one of the best Spectrogram apps of 2015

Needs just 1 thing

Please add a save feature. Works perfect but there have been times where I have needed to compare sound levels I can't because if I close the app it erases everything.

good, needs an options menu

pinch-zooming is very useful for pinpointing mid frequencies,though update response is choppy and I would have liked some options to change window size. there also needs to be a switch for logarithmic frequency scaling - linear display is only useful in a handful of situations. all and all a good design that just needs a bit of user customization
