Audio storage calculator for daily recordings
Estimate recording storage from daily minutes, bitrate and a retention period you choose. No audio file is needed.
Enter minutes per day, the encoded bitrate in kbps and whole retention days to get daily bytes and total GB/GiB.
Your result
Calculate the audio payload
Multiply daily minutes by 60, bitrate by 1,000 and the chosen number of days, then divide by eight to convert bits to bytes. For 60 minutes per day at 64 kbps across seven days, the result is 201,600,000 bytes: 0.2016 GB. The seven-day input is an example you may change, not a RecForMe retention policy.
Use the estimate as a planning floor
A variable-bitrate encoder, file headers, databases and duplicate copies can change real disk usage. Inspect actual file sizes before making a device-capacity decision. This calculator does not record, compress, delete or upload audio, and it does not describe an implemented RecForMe recording format.
