VAD (Voice Activity Detection)
VAD allows the T.sonic 615 to make gapless voice recordings. This means during voice recording with the internal microphone, the player will only record when it detects voices. If the person(s) pauses or stops speaking, the T.sonic 615 will temporarily stop recording until the person(s) starts speaking again. This allows for more concise, easier to understand recordings and smaller recording files.
