Sound Spectrum Pro Customer Insights

1. This is excrement on android phone.This is very good and okharganya cuma seratus ribuan mana akurat sih dan gw udh cobaCan you please allow the user to change the length of the sweep to use it in larger rooms? I can get a varying sweep in the octave band modes but not in the IR where I need it.

2. For frequency sampling, if software can load microphone calibration files, like Dayton iMM-6 provided, would be perfect for seeing more accurate frequency response.Great for frequency responses and calibration.

3. Wonderful tools! Quick response with good features like sweep sound and tone generation.

4. For measuring THD, as software needs to manually select the tone frequency to measure THD.

5. It will be difficult to select a tone or follow a sweep if using external sweep or tone.

6. UI is very confusing though, for the sake of ease of access i presume but it is very hard to set the app correctly.Hi, thank you for a very good application.

7. 20Hz to 20khz tested, RT60 accuracy via IR, 94 dB /114 dB spl calibration achieved.

8. It will be a +++ if the app can show in/out phase, STIPA readings and EQ suggestion in loudspeaker tuning & TF Snapshots Overlay.

9. Would suggest max peak also has the THD displayed along with the peak frequency and level.

10. Thank you! (Not Compatible with Android 10)Best on Android.

11. It really covers all the aspects of sound analysis.Really... Don't bother to purchase this app.
