Women’s Audio Mission courses focus on increasing the gender balance in audio production and technology sectors since less than 5% of the population employed in these sectors are women and gender-diverse individuals. There are limited spots available in our classes, and they often sell out, so we ask that if you are not woman-identified (cisgender or transgender), nonbinary, or gender-expansive, you reconsider enrolling in the class. We will not turn anyone away, but please be mindful that if you take up a seat in the class, that is one less woman, non-binary, or gender-expansive individual that we can serve. We thank you for your understanding in advance and for joining us in our mission to advance women and girls in music production and the recording arts.
