DarkEyes Posted September 16 Share Posted September 16 Hello. If anyone has made a long duration audio recorded, what audio recorder are you using? I purchased one that said it will record up to 1100 hours, but after getting it and reading the manual, that is only in the lowest quality setting. High quality setting caps out the recorder at 74 hours regardless of available memory space. Your recommendations are appreciated. Link to comment Share on other sites More sharing options...

Many of us use the Olympus LS7 or the Olympus 720 DM, both can be bus powered via a wired AAA modifier to a double D-Cell power pack to increase the record time to 450 hours { 45 10 hour nights ) in 128KB MP3 format. I plan on posting a video in the near future on how these systems can be made and the basic functionality. My friend Chris Spencer has some of this information on Youtube ( search his name ). 1 1 Link to comment Share on other sites More sharing options...
DarkEyes Posted September 16 Author Share Posted September 16 I’ll check out those recorders. I already have everything built and make. It’s super simple. It’s just the misinformation of the recording capability of the recorder that I’m primarily concerned about. Link to comment Share on other sites More sharing options...
Catmandoo Posted September 17 Share Posted September 17 Before you scrap your recorder, check the manual for "Recording Automatically" or perhaps "Auto Rec". Manufacturers use different terms for 'sound activated recording'. Generally posting, the recorder waits in standby mode and when a noise / sound is louder than your preset sound level, the recorder opens a new file and starts recording. Saves power and memory space. I don't think that you want countless hours of 'the sound of silence' I have to make some guesses. You set up to hack the battery compartment or are using a power bank with USB cable. I have done both but prefer my power banks. Olympus, Sony and others have made nice little voice recorders. One can view the user guides / manuals on line at B&H Photo Video to make comparisons before buying equipment. Reviewing the frequency response, battery types and memory capacity is vital. Go to the recorder manufacturer support page and find the list of 'supported media' that are approved. Many big name brands have models that are not approved. TASCAM makes recorders like the DR-05X and DR-07X that do not break the bank. $79 and $119 respectively. They have "Recording Automatically" ( Auto Rec ). Operate on 2 AA batteries and USB power port. Max memory is 128GB microSDXC card. The sweet part is they are '20--20' recorders. The low performance setting ranges from 20Hz to 20kHz ( 20-20 ) and the max setting is 20Hz to 40kHz. Most voice recorders are limited to 40 to 50 Hz. Zoom rolls off really bad at about 30Hz and they are still popular. I have Anker 20,100 mAh power banks that will drive a TASCAM DR-05X for days. I do not like to leave audio equipment out in the wild forest so I am in campsite mode. Reviewing: reading manuals at B&H is time consuming and helpful even if a purchase is not made. Entering the brand names and models also shows what units are no longer available. Good luck DarkEyes 1 Link to comment Share on other sites More sharing options...
