Signal Selection

Each tool within SoundMeter has its own toolbar, which appears at the top of the tool's visible area within the app. For tools that acquire live signals for analysis or data acquisition, a channel selection button appears on the left side of the tool's toolbar. Tap the button to bring up a Channel Selection menu. SoundMeter supports the selection of input and/or output channels for analysis or data acquisition. Support for output channel selection means that Signal Generator output can be analyzed or recorded directly (SoundMeter cannot directly analyze the output of other audio apps).

The Octave and Data Recorder tools allow for multiple channels to be selected, simultaneously.
