Description
A spectrogram version of iSpectral. The App displays fast gram data taken real-time from audio microphone data. Useful for musicians, piano, guitar and speaker tuning, sound/acoustics engineers, sonar, signal processing engineers and hobbies interested in recording environments.*NOTE to customers*
Please informed us (idroidbot@gmail.com) if you have any issues running the App on your phone or you are not completely satisfied. We can issue you a refund. Thanks, VT
Here are the highlighted features:
1. Selectable sample rates and FFT size.
2. Matlab like colormaps.
3. Two crossbars for easy readout and calculating the deltas.
4. Records data for playback. The recorded data can be outputted to file or socket.
5. Any many more!
Hardware permission required by this App:
1. WRITE_SETTINGS - This is needed to change the display from sleeping.
2. RECORD_AUDIO - Data taken from microphone.
3. INTERNET - This is required for transmitting audio data over a socket.
4. WRITE_EXTERNAL_STORAGE - Save recorded audio data to SD for playback.
6. And many more!

*Hardware Note*
Since each phone has different hardware, you may need to increase or decrease your sample rate or FFT size setting to get optimal response.

Good, but could use features This app generates nice spectrograms of the mic input; however, the software is lacking some basic and obvious features. First, the app does not save user settings from a previous use, such as the preferred color scheme. Second, there are no zoom options for time or frequency axes. This can be done to some extent by adjusting sampling rate, but this is not a convenient way to do this. "Pinching" commands like on google maps would be really nice! A basic FFT line plot mode would also be a nice feature.

Why, why, why is there no zoom feature? And why timer doesn't resolve sub-seconds; just seconds only? Dev: Presume app is used on device only.

Very Nice. I have been able to use this to identify and isolate a number of sounds. Very simple to use. Looking forward to find new uses for this.

Thumbs up !!! Thumbs up to this software, very impressive work on the color changes gram. And many setting option to choice very simple to use. This software is very stable, highly recommended.
