• 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.
