App Description
General purpose room frequency response and sound meter tool

• View real-time amplitude and frequency data from the phone
• Store last recorded amp/freq into the built-in database
• Built-in 5kHz, 8kHz tones and 20-20kHz sweep
• Fine control over graph update speed.
• Open source
Permissions:
• You will need to grant microphone access for this app to work. This app is completely offline so all data remains on your device.
