Hey guys, thanks for chiming in. I did a few searches but didn't even find a mention. I'm presently researching digital voice recorders and some Sennheiser clip-on mics. These may or may not be an ideal fit though. Ultimately, I am piecing together a high sensitivity lapel mic and recorder to capture whispers and mumbles throughout the day. Ideally, I want capabilities to send to voicemail or a more competent service for transcription to text. First, I need to narrow down product options that are capable of clearly capturing whispers and mumbles from my voice amidst a full range of background noise. This is what I am searching for suggestions or experiential reflections. What range of frequencies are whispers and mumbles, and what equipment would best handle this?
