Development projects

AES-X218: Measurement and calibration of sound systems in rooms.
David Prince summarized status. Writing group was meeting twice a month with a few cancellations. Work was progressing slowly due to other obligations. Neither the measurement standard nor the Information Documents were at a review point yet.

The conclusion from the May meeting that x219 should be scrapped and incorporated into the x218 document had not received any objections since the May meeting so DP instructed for Rich Cabot to discontinue x219.

Liaisons

Brian Vessa and Lon Neumann provided updates on SMPTE activity paralleling x218 Progress with heavy emphasis on Dialogue intelligibility.

DP noted recent JASA social media post (on article in April 2023) outlining change in vocal level vs background; is there something similar for Cinema dialogue vs background. The analogy of genre was noted - in music country vs metal (in the JASA article) is similar to drama vs special effects genre in cinema classification.
