The storage space taken up by an uncompressed, full-spectrum audio recording is a product of four factors:
- The length of the recording, in seconds
- The sample rate of the recording, in samples per second or Hertz
- The bit depth of the recording, in bits per sample
- The number of recording channels
All of our recorders produce .wav files with a 16-bit depth, except for our marine units, which can optionally be configured to record with a 32-bit depth. The sample rate of our recorders is user-configurable.
You can use our free Song Meter Configurator software to estimate when SD cards of any size will fill up based on your recording schedule and audio settings.
