improved markedly due to an increased focus on multi-track recording, greater access to home recording technology, and the emergence of professional a cappella production specialists (including arrangers, vocal editors, and mix/mastering engineers). Achievements in collegiate a cappella recording are recognized by awards programs (e.g., the Contemporary A Cappella Recording Awards, awarded by CASA) and compilation albums, such as the long-running Best of College A Cappella series. The bigger the groups, the more the groups tend to really connect. Through all the rehearsals, learning the differences of your peers, yet sharing the same goal, can be challenging. Competing also brings about club unity and encourages the groups to share personal experiences the group has gone through together. Many college groups compete in annual competitions organized by the International Championship of Collegiate A Cappella (ICCA), which conducts various regional competitions, with winners of regional competitions advancing to a national competition.
