Makeshift studio away from home.
I was in London visiting a dear friend and an audition came in. So I hopped in her closet where the clothes help stop the reflection of sound, grabbed a glass of water to stop the mouth clicks, plugged in my travel USB microphone and Bam-booked the job!
Advantages: at least twice the size of you home studio, it is heated, no construction noise, very neat, lots of shoes. Disadvantage: no window
Actually no window IS an advantage! It’s better for soundproofing. With the window I have to pause for trains, planes and motorcycles oh yeah and crickets!
