4.3 Storage'Requirements'
How many recordings you can store on your Android device
depends on the capacity of your device and how much
memory is available. A 5.0-second recording uses 2.5 MB of
storage. A 32 GB phone with 28 GB of storage available, for
example, would be able to save over 10,000 recordings.
Many Android devices accept external SD memory cards. An
upcoming release of the app will allow recording to an
external card.
The app also needs at least 600mb of internal memory
storage for sufficient buffering of Live Mode. The app will
warn you if you have insufficient storage.
