"I can confidently say that working with So Big Auditory caused the quality of my songs to improve significantly. Throughout the process, I felt the love and knew that my songs were in good hands." -Sylvie of Jungheim

"Working with Heather on 'Waterfowl' was seamless. They worked so quickly and balanced our vision with theirs perfectly. Mastering's artistic fingerprint can be tough to pick out, but the album sounded tangibly warmer and brighter after Heather worked their magic" -Jack of Frankie Valet

"I have been a fan of Heather's music for a long time. What has always struck me was how good everything sounded on the projects they were involved with. I knew that I could trust their ears and instincts. Working with them could not have been easier. I had my masters back quickly and everything sounded noticeably warmer and brighter. I was impressed but not surprised." -Andhi O'Neill

"Heather (the brains behind So Big) is a world-class professional/artist with a humble hometown attitude and approach. Simultaneously, ‘So big’ with a charming attention to the ‘so small’. This is also true of the sonic range of the studio. Heather knows how to create bigness from the smallest of sounds and moments and Ofcourse visa versa. So Big is a gem of the East Coast music scene (particularly the Jersey/Philly area), both spatially and conceptually. If you have interest in song development, So Big takes a song-first approach and Heather is an active listener at every stop in the process. I’m so blessed to have worked on a project there and can’t wait for the records to come, personally and from others within the community that So Big nurtures. Best of luck and well wishes to this beautiful creative space! Get your next record mixed, mastered, and/or engineered at So Big!" - Hanny Ramadan of Latchkey Kids


So Big Auditory is a modern hybrid studio.In an era of music production where the sound quality of digital and analog processes are almost indistinguishable, we have a responsibility as engineers to hold our processes to a higher standard, and ensure that we provide the best sound for the rates we charge.This is why the front end at So Big has been revamped around a digital system. Tracking is now an equal parts digital and analog process. Don't worry--the tape machine still available and hooked up for use.With industry standard DSP for coloration and flavor, true transformer and tube paths for extra grit, and mastering-grade playback/monitoring, sounds captured at So Big stay big wherever you listen. Discerning clients will be happy with the low noise floor and impactful dynamics, while folks newer to recording will enjoy a process that is fast and exciting.While So Big is generally not equipped for ensemble recording, don't hesitate to reach out--scheduling can sometimes allow for larger group sessions.So Big is located on stolen Lene Lanape territory known as West Philadelphia.
