I'm planning a human subject data collection project and need to understand the LDC's recording capabilities. Can you describe the soundbooth's noise reduction and audio quality features, and list the general types of microphones available for data collection at their facilities?
Navigate to 'catalog.ldc.upenn.edu'. Search the LDC Catalog for 'Human Subjects Collection' using the 'Find keywords in corpus description' field. Click the 'Search' button. From the search results, click the link for 'LDC2013S03 Human Subjects Collection'. Scroll down the 'Human Subjects Collection' page to locate the 'Recording Facilities' section. Extract and summarize the soundbooth's noise reduction and audio quality features. Extract and list the general types of microphones available.
Successfully navigate to the 'LDC2013S03 Human Subjects Collection' page. State that the soundbooth has an acoustical seal and drop sweep on the door, a multi-pane window, and two layers of acoustic treatment on walls and ceiling. Mention that audio and control signals are routed via customized wallplates to a rackmounted digital audio workstation outside the soundbooth to minimize noise. List the types of microphones available as: studio, lavalier, headset, and general purpose microphones.
