Reflection filters, or portable vocal booths, have become a standard piece of equipment in both home and professional studios since they first came on the market a few years ago. These filters use a simple concept to solve one of the big problems standing in the way of getting good sounding professional recordings. Instead of putting up acoustic treatment all over your whole recording room, the reflection filter effectively treats only the area right around your microphone where it makes all the difference.
Post Audio was one of the original pioneers in this field and they continue to hit the sweet spot with reflection filters that do their job very well, with professional quality and are still reasonably priced. That’s probably why Post Audio is the largest maker of reflection filters in the USA.
