Wonderful tools! Quick response with good features like sweep sound and tone generation. Can read THD is a good plus! Several suggestions: 1. For measuring THD, as software needs to manually select the tone frequency to measure THD. It will be difficult to select a tone or follow a sweep if using external sweep or tone. Would suggest max peak also has the THD displayed along with the peak frequency and level. 2. If can draw THD vs freq after sweep(internal or external), would be perfect. 3. 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. 20Hz to 20khz tested, RT60 accuracy via IR, 94 dB /114 dB spl calibration achieved. Can print pdf for reports, able to load . frd and. cal files from calibration lab. Sweep/Noise acurate. It will be a +++ if the app can show in/out phase, STIPA readings and EQ suggestion in loudspeaker tuning & TF Snapshots Overlay. Awaiting further development. Pls mention IEC/ISO standards followed. Thank you! (Not Compatible with Android 10)
Best on Android. UI is very confusing though, for the sake of ease of access i presume but it is very hard to set the app correctly.
Can 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. Also can we have a better way to export an IR to a usable file format? This app is fun and interesting but it has some flaws before it's perfect
It is an amazing customisable app, probably the best for android. Definetely recommend for others
Excellent features as compared to similar apps. Easy to use but also suitable for engineering applications. Well worth the $.
app only showing quick snapshots, looking for rta. constant measurements.. not a few seconds
Tried this to measure RT60 of a space. Neutrik A2 analyzer shows 5.7 seconds. This app showed 1.25!!A huge margin of error!
Hi, thank you for a very good application. I use it almost daily. It is specially useful to be able to compare readings from different times. It really covers all the aspects of sound analysis.
