1. Wish there were a way to manually set axis limits and prevent accidental change upon touching the screen.Great work!totallyI'll start by saying that the original (free) version was/is the best spectrum analyser there is for Android if you want an engineering tool.
2. Otherwise nice app, a Help section would be helpful.Opened and uninstalled in seconds, has no use for me.measuring audio filtersVery useful appThere are some improvements from the old version, but also there are some annoyances.
3. i need to record short samples of the industrial noise sound, which happens randomly.
4. In particular I want to be able to force landscape mode and disable rotation.
5. version 1.Poor resolution at low frequencies due to only having high sample rates.
6. The save profile feature is a massive improvement over a screenshot but it's not clear when it saves the waveform (capture button would be nice).
7. If I disable auto rotate of my phone, it is always in portrait mode.
8. Portrait mode is useless, but it constantly switches to it while I use the app.
9. I need sample rates down to 8 kHz, preferably 4 kHz.
10. Unfortunately the app does not record continuous samples.
11. No readout for peak frequency, particularly one that can can be held long enough to look at it after looking over at something else in the room.
