Record and export received audio
WAV files contain receiver audio, not microphone recordings.
Start compatible FM/AM reception, then choose Record audio. Recording is optional and captures demodulated receiver audio. BandSight does not request microphone access.
Use Stop recording and wait for the completion message. Native recordings are bounded to ten minutes. Interrupted or failed storage must be checked before treating a file as complete.
Export recording saves the latest completed WAV through Android’s document picker. Choose a trusted destination and wait for success. A failed or canceled export keeps the private original.
The WAV is unencrypted and may contain sensitive received content. Export important completed recordings before starting another session or clearing app data; the visible export action is not a recording-library backup.
