EQ

Shape each element of your mix with pre/post tape EQ options. Boost lows before tape for extra saturation or roll-off highs after tape for a vintage, softened feel.

Calibration

Use Noise and Instability Control to introduce authentic tape characteristics. Add tape noise for vintage realism and simulate mechanical wear for some wow and flutter.

Delay Loop

Add space and movement to any sound with built-in delay feedback. Introduce subtle phasing and flanging effects or create a slapback delay to bring life to recorded instruments.

The holy grail
of tape recording

The Studer J37 is part of a lineage of iconic recording equipment that shaped the sound of the 50s, 60s, and 70s.

It isn’t just another tape machine - it’s an icon of audio craftsmanship and music history. Hailed for its exacting Swiss engineering, the Studer J37 was adopted by legendary artists like The Beatles, Pink Floyd, and Jimi Hendrix. As a result, its trademark warmth and clarity wove its way into some of the most influential albums in recorded history, cementing its position as the gold standard for mid-20th century multi-track tape recording.

A machine with
a storied past

The unit we modeled isn’t just any J37, it was once housed in Studio Barclay: the “Abbey Road of French music” that hosted iconic artists Édith Piaf, Serge Gainsbourg, and Jacques Brel.

Decades of recording sessions imparted this model with a unique musical patina and spirit, carrying the echoes of countless performances. Now housed at Studio D.E.S under the care and maintenance of Poussin Kechit, we got to go under the hood of this audio engineering marvel to gather key internal measurements and reproduce its tape states and calibration settings.

Tube-driven
precision

Beneath its robust metal frame, the J37’s greatest secret was its array of more than 50 vacuum tubes, each working in harmony and giving recordings a warm and distinct color.

The glowing triode filaments offer a manageable signal-to-noise ratio as well as producing a sound with natural compression. Combined with the machine’s impeccable design and studio performance, engineers were able to push recordings to their creative limits without compromising clarity. Using state-of-the-art modeling techniques, we’ve made sure to accurately reproduce the J37’s thermionic essence, preserving its rich tone and remarkable sound.

Recreated
like never before

By employing a neural-based modeling framework and conducting painstaking multi-stage measurements, we’ve methodically mapped the exact interactions, harmonics, and tape states that define the Studer J37’s distinctive sound.

The result is a truly authentic recreation brought to life with state-of-the-art digital signal processing, enabling us to capture every detail and idiosyncrasy of this legendary machine. Tape J-37 infuses any input with an analog sheen that is indistinguishable from the real thing.
