This voice recorder has an innovative line input terminal, allowing you to capture audio from external devices such as microphones, telephones, and CD players. In case of emergency, call recordings saved via line input can serve as important evidence. You can always make calls with peace of mind. 【360° Omnidirectional Sound Collection & Double Noise Reduction】This IC recorder is equipped with a high-performance microphone, capable of collecting sound from 360° in all directions, and can clearly capture even distant or small sounds. In addition, it is equipped with an advanced DSP chip for noise reduction processing + a 7-stage adjustable noise canceling function, which effectively eliminates noise interference from the sound source to the maximum extent, faithfully reproduces the sound, and achieves a clearer and more beautiful, immersive 1536kbps high-quality sound. 【OTG Function Supported & Date/Time Synchronization Recording Possible】This recording device is equipped with an OTG function, allowing you to play back recordings on the voice recorder itself. Furthermore, by connecting it using an OTG adapter and the included USB cable, you can listen to, move, save, and delete recording data on your smartphone (Android & iPhone) or computer. Also, since the recording data is recorded with the date and time, you can edit it according to your needs after connecting to your smartphone or PC. (Android & iPhone smartphone conversion adapters are sold separately. Please note.) 【Voice Activation Recording (VOR) Automatic Recording】The voice activation recording (VOR) function means that the voice recorder automatically starts recording as soon as it detects sound, and pauses when it does not detect sound. Then, if it detects sound again, recording restarts. The recordings before and after the pause are continuous. 【Fast Forward/Rewind & Repeat Playback Function】When using a voice recorder for language learning, such as for lessons or memorizing vocabulary, the "speed adjustment function" and "repeat function" are important. Our voice recorder allows you to control fast forward and rewind by long-pressing the "UP" or "DOWN" buttons, and can be adjusted to approximately 5x speed, allowing you to quickly reach the point you want to check.
