Effects of Reflections: Impulse Response and Reflectogram

This lecture discusses the effects of reflections on sound, including examples of recordings in different room conditions and how reflections can impact speech and music diffusion. It also covers the concept of reflectogram/echogram, which shows the time series of reflections in a room through impulse response measurements using various sound sources. The lecture further explores impulse response measurements in empty and full rooms, as well as the reverberation time processing in different room types.
