Customer Reviews

gives real frequency info!

arrogantb

Other cheap similar apps only make pretty pictures.

This one gives you labels and you can tap at a spot on the chart to see the corresponding frequency.

Highly useful for basic audio analysis.

Functional

Though perhaps not feature-laden, this app is certainly more than a toy. Has four different types of windowing, multiple scales and manually adjustable cursors. Definitely a good deal for $2

Suggestions

I like the app,nicely done, but I would really like to be able to specify a number of samples and then average the amplitudes at each frequency ... This would enable me to pick out dominant frequencies and get rid of the random noise.
