Ratings and Reviews
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.
gives real frequency info!
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.
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
With Family Sharing set up, up to six family members can use this app.
