What is the size of one minute of recording?
Here are the approximate sizes for 1 minute of recording:
| Quality | Size for wav | Size for m4a |
| 8 kHz | 1 MB | 0.12 MB |
| 16 kHz | 2 MB | 0.27 MB |
| 44.1 kHz | 5 MB | 0.54 MB |
| 48 kHz | 5.5 MB | 0.68 MB |
Memos that are recorded in stereo will require more storage space. If you are using the uncompressed wav file format, twice the amount of space will be required compared to recording in mono. When using the compressed m4a file format, 80% more storage will be used.
To see the amount of free space on your device, open the Settings app and go to General -> About -> Available. To avoid unexpected behaviors, we recommend you have at least 1 GB of available storage space before you start recording.
