Audio Spectrum Analyzer App Reviews

Great App almost exactly what i was looking for! Great value. It works smoothly and easily. Minuses? Yes I wish it went to 40 kHz! While 20 covers the audio spectrum for most people, a few people (and most dogs) have hearing above that range. The instructions for selecting the filtering window need to be expanded. Other than those two minor whines, it is a great app

Does exactly what it says on the box. Sometimes buggy (at least on iOS9). Zooming sometimes doesn't work. Resuming the app after switching to something else makes it not display frequency data. Not perfect, but more than acceptable.

Recommend this for novices and pros. Great for setting up a sound room or booth. Good Job!

Happy with this app. Frequency markers on peaks very handy. Checked against 500 and 600 Hz tones on WWV and both were within 0.1 Hz. Recommended.

Great tool for analysis of audio sound.

Intuitive, simple, powerful. Read the FAQ, which is the user guide/manual.

Excellent tool for analyzing sound background noise, and data transmission modes. Features allow zooming in and out and peek hold.

Very useful, but it would be so much better if it could do a running average of the spectrums. This would help to pull signals out of the noise floor.

Cannot pinch to zoom in frequency domain as it states in FAQ. Needed this app to identify specific higher frequencies but the ones I want get overshadowed by low frequency noise and I can't zoom those out of window. Labeling the peaks by touching them would be nice rather than app only labeling overall maximums.
