Appmuse

It’s very difficult to use over Bluetooth. The app has no settings to select the audio output device and seems to prefer the built-in speaker.

Add 16384 32768 and more fft, for better low frequency resolution.

I bought this app last week. Before I used the Lite Version I was very impressed this app so I bought this app! But Full version has a big problem! FFT spectrum Line is not detail even more than Lite version. I want to fix that problem! Thanks! Show more

The latest update crashes immediately on my iPhone 5s running iOS 7.0.2. Won't open at all.

Very useful for live audio reinforcement.

I use this app for live PA setups and even in the studio sometimes to identify a runaway frequency. It's accurate, fast, and updated for the 5. Well worth the money if you're an audio junkie. The SPL meter and sig generator are both useful tools. Show more

Fires up fast, directly to the screen you want. Responsive display. The peak frequency number is really visible and doesn't move around. I use it to identify feedback frequencies while tweaking the PA during setup. Show more

We are testing speaker phone ranges with it.

This App uses windowing in the FFT to reduce noise. Good resolution (3 ranges selectable). Useful for checking feedback. Handy to have the built in signal generator and SPL meter also. Scope is expandable in both directions. Plenty responsive. Good value for money. Show more

All of the features you'd want are here, but bone of them are executed particularly well. The FFT looks nice, but it's not responsive, and the resolution is low. The oscilloscope looks nice, but it can't zoom out very far and it's slow. Basically useless for transient signals. Couldn't figure out how to use the trigger mechanism. There are better apps out there that do the same thing but better. Keep looking. Show more

I would like to see a peak hold option in the FFT, that would be the most beneficial for quick tunings. Also, might as well throw a sine wave sweep in there as well. Adjustable start stop hz and length of time it takes to complete the sweep. Show more

This is a fun app for geeks. Physics teachers will find it handy, especially. I wish there were some control over the FFT display - it would be nice to look more closely at narrower frequency ranges. One flaw that bothers me is the artifacts from the sine-wave generator at high frequency. Presumably due to aliasing, a low frequency tone is often produced. Young people who can actually hear signals at >12 kHz probably won't notice it. Show more

This is one of the best values on the web. The program is well written and very functional with good instructions.

Nothing but the frequency generator seemed to work, which is odd given the recent update.

Finally a real FFT spectrum analyzer at a fun price! This compares well to apps at ten times the price and delivers an FFT spectrum of what the mic hears with 43 Hz bin resolution, automatic labeling of the peak frequency, and a built-in sinewave generator and SPL meter! Only drawbacks: no vertical axis labels, so not really useful for fine EQ (the y-axis is logarithmic, and appears to cover around 100dB); no options to change FFT length or window shape. Show more
