Signal Path is the most performant spectrum viewing app with beautiful user interface. You can record audio spectrums using microphone and replay them or open large recordings containing I/Q data. Inspect spectrums Spectrums can be selected using two finger drag gesture. Tapping on histogram reveals amplitude value of the selected frequency bin. Adjust thresholds Signal Path automatically expands amplitude threshold range when viewing spectrums. You can also set custom amplitude thresholds if needed. Keeping file size under control Signal Path can set a maximum file size for recording after which file is recreated. Can open wav files and save recorded audio as wav Supported interleaved raw I/Q data formats Float, int8, int16, int32, uInt8, uInt16, and uInt32 Fast Fourier transform lengths 256, 512, 1024, 2048, 4096, 8192 Window functions Rectangular, Blackman, Hamming, and Hann

works well enough, but has some inconveniences

I wanted to use this app to find the source of a high-pitched whine in my apartment, but it doesn't let you scroll left/right while recording, so I couldn't see the higher frequencies unless I stopped recording. I was able to figure it out, but it was inconvenient...It's also not obvious to me how you select a time range in the graph; it seems to be related to tapping with two fingers, but I can't do it reliably.Anyway, time to move the noisy thing to a different room :p thanks for the app

Fair Enough

The app in itself is fair enough but there are limitations. First nowhere to be found is help, maybe I’m missing something but I searched and searched to no avail.Second is recording playback. I can record fine but when I try to playback all I get is about a fraction of a second of sound. Again, am I missing something?No instructions anywhere on learning the app’s functions? Again, again, am I missing something?Need help..

Crashes when creating a new audio recording

Really promising app, unfortunately it crashes when you try to create a new audio recording from the menu. A fix would be greatly appreciated for a $9 app!

Developer Response
Thank you for reporting it and I am sorry for encountering this. This issue is fixed in version 1.5.

Can’t open pre-recorded files

Wasn’t clear from the description (since it said "import from any source") but the app won’t import a pre-recorded file. There is no help file, nor documentation. Tried .wav, mp3, and m4p without luck.

Developer Response
It does support wav files in recent versions. The description was not as clear as it should have been.
