I would like to do voice recording in the field, but have no access to a PC close to the sound system in the auditorium. I thought I would try an Olympus VN-480PC voice recorder with a 40dB cap-coupled attenuator that will go between a Mackie audio mixer to the mic input of the recorder. The attenuator has a low 3dB cutoff of less than 20 Hz. As I record voice from the local NPR FM broadcast station, there seems to be a slight distortion on the recorded clip. I could attach a small mp3 to demonstrate, but I haven't figured out how to do that. Voice recording is all that is required, so HiFi is not necessary, however, the distortion is annoying. Am I barking up the wrong tree to try to use a voice recorder for this application?
Is the problem with just this voice recorder or will it be like this for all of them?
Is there another way to do portable digital recording while having reasonably good sound quality?
