Final answer:
Audio-visual productions utilizing synch music are declining, and aggregate payments are shrinking.
Step-by-step explanation:
Audio-visual productions utilizing synch music are declining, and aggregate payments are shrinking. This statement is true. With the rise of digital streaming services and the decline of physical media sales, the revenue generated by synch music in audio-visual productions has decreased. Additionally, the availability of royalty-free music and the ability for artists to self-produce and distribute their own music has contributed to the decline in aggregate payments.
