Giant Heartbeat

Professional Audio Mastering for Streaming

At Giant Heartbeat, we specialize in mastering music for streaming platforms, ensuring your tracks meet industry standards for clarity, balance, and loudness. Unlike automated A.I. mastering services, our approach is fully human—every track is carefully processed by an experienced engineer in our NYC studio, to bring out its best qualities while preserving its dynamics and unique artistic intent. Mastering services are provided entirely online.

We optimize your music for platforms like Spotify, Apple Music, YouTube, and more, adhering to modern loudness targets (typically -14 LUFS for most streaming services) while maintaining punch, depth, and dynamic range. Our goal is to create a balanced, professional sound that translates well across all playback systems, regardless of genre or production style.
