Astrum Audio

Astrum Audio is an audio visual consultant serving Spring Valley, CA and surrounding areas. We help filmmakers shape sound. Our dialogue editing improves clarity, while ADR services create replacement performances that fit each scene. We produce polished voice over recordings and craft a re-recording mix blending dialogue, music, and effects. Our mixes meet LKFS loudness standards for shorts, documentaries, and narrative projects. Audio QC & review catches issues and supports release-ready sound. We prepare deliverables and stems to match project specs, keeping files organized. With attention to detail and quality, we support productions through final delivery. Contact us to discuss your project.
