dB9PROVoice Activated Digital Recorder with USB, 8GB, 48 Hrs Capacity Sound Recorder, Audio Recording Device with Built-In Microphone, Gray, Mini Dictaphone for Lectures, Meetings, Gift for Students

I brought this a while back to record sermons on for my church. We actually have a hand held so this is a back up. Not tried it yet but have tested it and it does seem to meet the requirements

Came in nice metal box.Easy to use.Audio quality not great, can sound of bit like you're recording 'under water'.Not impressed with the 384 kb/s record bitrate (24KHz * 16bit mono = 384Kb/s).In documentation (manual), and in product info (on their site), say 48KHz sampling rate,is not, is 24KHz sample rate.Actual frequency range = 24KHz / 2 = 12KHz max (nyquist theorem).MediaInfo result:GeneralComplete name : H:\RECORD\20230709153319-001.WAVFormat : WaveFile size : 7.98 MiBDuration : 2 min 54 sOverall bit rate mode : ConstantOverall bit rate : 384 kb/sAudioFormat : PCMFormat settings, Endianness : LittleFormat settings, Sign : SignedCodec ID : 1Duration : 2 min 54 sBit rate mode : ConstantBit rate : 384 kb/sChannel(s) : 1 channelSampling rate : 24.0 kHzBit depth : 16 bitsStream size : 7.98 MiB (100%)I guess its my fault for not paying too much attention, it is though a handy little deviceand I am keeping it on a keyring.PS, another manual on their site (see warranty card).Also firmware on their site, but dated 2016.

I wanted to post this review as i recently purchased this 8gb flash drive secret voice recording device very recently, & i have to say that im pretty impressed!Prior to purchasing this one, I browsed several here on Amazon, & read TONS of reviews. I was more so looking for quality, rather than price, as obv i wanted a price that was reasonable, & affordable, - not the cheapest, yet not wanting to pay the earth, but i was specifically looking for the best in terms of its inconspicuous discreet appearance, with good quality voice recording, a long battery life, & also, easy to set up & operate. And THIS was the one which I opted for, based on those required specifications. It was also, at £21.99, I felt, a reasonable price to pay, for what it is, & im so glad that I did opt to purchase this one!It arrived speedily, which was great!👌 & was well presented, in a slim yet sturdy tin presentation case (so ideal for giving as a gift), and within its case also came a small, long, pull-out instruction booklet, & an attachment for being able to attach the flash drive to a keyring, & also a black lanyard, which is really useful!Note: this device charges via USB connection to either a computer / laptop, or simply by inserting the USB stick into a USB mains plug, as in, most charging adapter plugs have a USB connection, for inserting micro USB charging cables, or apple lightening charging cables, which can be easily removed, for this flash drive to be inserted into. This device needs an initial full charge of 3 hours. This device has a battery charging/charged indicator light, which changes from red to blue.After this initial full charge, the flash drive then needs to be inserted into the USB port of a laptop, then simply follow the setup instructions booklet, - which, honestly, its set up is soooooo easy, & is really quick to set up too, then, this device is ready to go!This device is so very simple to operate, & also simple & hassle-free to transfer its recording to a computer / laptop.The playback sound quality of recordings is also really good👌 - playback is clear, & this voice recorder has a good pick-up range too.Needless to say, I'm VERY happy with my purchase, & i would deffo HIGHLY recommend.I hope you have found this review helpful, 😉, xx
