With Bluetooth headphones or speakers connected, the spectrogram and waterfall could come up almost empty. Those two views were the only ones listening through the Bluetooth microphone. The settings now have Use Bluetooth Microphone, and while it is off the app listens through the device's own or a wired microphone. It is off by default. Also in this release - When the microphone does not pick up high frequencies, the frequency scale now stops where the microphone does - On light themes, the spectrogram and waterfall used colors unrelated to the theme. They are now built from the theme's own colors - Fixed: text on accent-colored buttons and pills could be hard to read - Analysis settings moved to the screens that use them. Pre-emphasis and whitening for the spectrogram are now separate from the other views
