Notes:
Compression is a function of bit rate, measured as kilobits per second (kbps). Lowering the bit rate increases the compression and diminishes the sound quality.
This is a ROUGH guide to recording times on various card sizes. Please bear in mind that these are approximate times for Stereo recording.
If in doubt check specific manufacturers information relating to recording times.
Doubling the memory sizes provides approximately twice the recording time.
