Unsure of where to post and this seemed most accurate. I am doing a project about blindness and reliance on other senses. I am going to follow my cousins on a hunting trip and want to record the audio the entire time. Later I will edit this audio down. The problems are lack or power source for most of it. What should I buy that can record a week of audio without needing more power? Would it be easier to get a camera and just isolate the audio track afterward? Ideally I would have one recording at the camp going 24/7 and another to carry with me on outings, this means it can be a day or two between being able to change batteries at the camp. It's not super important to be able to do it without changing batteries all the time but thought maybe you guy could give advice.
