No special equipment, a quick cellphone recording at the beginning of my own personal vocal practice to fix mistakes as I adjust to singing in this part of my upper chest voice with as little effort as possible. Also trying to smooth out transitions between falsetto and chest voice. Recording an unadulterated quick practice also lets me know which areas i tend to go out of tune, rush, lack breath or annunciation before i put more effort and thought into singing the song.
