Comments on Spectrum Spectrogram Analyzer for Android
★★★★★
This is the best spectrum analyzer I've tried on Android. The only caveat is the lack of peak hold. Could you please add an option for that?
★★★★★
Wish It Had A Feacher To Import Mp3/Mp4 Files. Because The Only App That Has This Feacher Has Bad Reviews. All tough This Is A Great App! (Sorry For My Bad Spelling)
★★★★★
Not sure if it's the microphone, but the app doesn't work. I try to make sounds and the graph only picks up noise
★★★★★
It's the best one, there are a few apps put there that make you pay for basic features that this app has for free, 10/10 would bang
★★★★★
This is the ONLY spectrogram app that can accommodate my voice training, at least on the play store. Well done imo
★★☆☆☆
I could not open files and analyze them.
★★☆☆☆
Does not work. Gets 0 bytes from any source
★★☆☆☆
Couldn't do anything with this, showed all kinds of sounds on the graph while I was in a silent room trying to get the white noise to play out Bluetooth?
★★☆☆☆
Stupid, I'm trying to find a spectrogram app that plays audio files and I can't find one, please add that to the application
