The simple understanding is that if a noise with the number1comes, then add -1 to him, and the result is 0; The amplitude and wavelength of sound waves of different frequencies are different, and the corresponding algorithm for judging the amplitude and wavelength of noise sound waves, and generating inverted white noise through the DSP chip, determines the effect of noise reduction.External noise Inverted white noiseIntelligent voice- activated Automatically record when there is sound to save storage space as much as poible, and also savetime to play back and filter usele clips.Audio Silent pauseSmart timestampsAutomatically record the start time, convenient browsing management, accurate to minutes and seconds(such as: 20221210111520.WAV).Start 20221210111520Native removal functionPlug in the matching in-line headphones todelete files locally.Connect the in-line headphones Delete files nativelyPowerful battery life Standby up to 30 daysUsing 300 mAh environmental protection lithium battery and optimized energy-saving system, im prove the service life, the longest standby up to 30days, continuous about 50-60 hours.30 day Standby time 50-60HContinuous timeSave without power Shutdown protects filesBefore the power is turned off,the file g re corded is automatically saved to prevent thefile from g lost.Low battery detected Save the file automaticallyThe phone views the file OTG connects the phoneConnect the OTG adapter to view and manage files on the mobile phonesupportAndroid/Apple phone connection, plug and play,simple and convenient.Support Android and iPhone connectionOr music playback Work-life balanceAn electronic watch for commuting/leisure, pluing in headphones to listen to beautiful melodies and let themusic accompany you.Suitable for use scenariosThe use of busine meeting records, student study notes, reception interview s, etc...Busine meeting minutes are usedStudents learn to take notes on audio sReception interview Product Details DisplaySpecifications:Previous songUSB interfaceBoot/Record/ Next ckProduct model :D5 voice Product color: blackBattery capacity :300MAHCharging time :ABOUT 2H time :50-60HStandby time: About 30 days format :WAVProduct size: Sp 27cm/dial 2.6*5.6*1.4cmProduct weight :Approx.34gPack acceorieshost boxMicro data cableearphoneInstructions
