The amount of storage an audio recorder has can vary depending on the model and brand. Some may have built-in storage with a capacity of a few gigabytes, while others may have expandable memory options with the use of a micro SD card. The recording quality and format can also affect the amount of storage required.
Assuming an average bit rate of 128 kbps (kilobits per second) for MP3 files, a 32GB SD card can store approximately 320 hours of audio. However, if the MP3 files are encoded at a higher bit rate, such as 320 kbps, the storage capacity will be reduced accordingly. Conversely, if the files are encoded at a lower bit rate, such as 64 kbps, the storage capacity will increase.
It’s essential to check the storage capacity and recording format before purchasing a hidden recorder to ensure it meets your recording needs. Additionally, it’s crucial to transfer the recordings to a secure location regularly to prevent storage from running out and losing important data.
