For the recording of bird sounds, the compact recorders of Tascam, Olympus and Roland usually suffice. We even offer a handy windstopper. Do you want to record birds, insects, mammals, frogs and even aquatic life in extreme detail? Then we recommend the SM4 audio recorder from Wildlife Acoustics. This recorder can record up to 450 hours of sound because it offers space for 2 512 GB memory cards.
