Recording and mastering studio of Dureco based in Weesp, the Netherlands, which operated under that name from 1973 to 1999. The studio was constructed together with the Dureco fabriek in 1972 as part of Dureco's move from Amsterdam (where they had also operated a smaller studio) to Weesp. Dureco spared no expenses in designing a state of the art 8-16-24-track studio with quadraphonic facilities. The studio also contained a mixing and montage room and its own cutting room with Neumann equipment.

The first studio manager was Dick Bakker, who was succeeded by Jan Quintus Zwart in 1985. Other recording engineers who have worked here include: Sander Bos, Emile Elsen and Sytze Gardenier.

Records cut at Dureco used a three or four character code/signature [w]wA[A]n, where [w]w is one or two digits, marking the week of the year the record was cut, A[A] a single or double initial of the engineer who did the cut and n the number of the cut. In these cases the studio can be credited with Lacquer Cut At and the engineer with Lacquer Cut By, using the appropriate ANV for the initial(s).

Main mastering engineers:
- Paul Dobbe (1971-1974), signed with D.
- Kees Grijpink (1972-1990), signed with C (the initial of Christian name Cornelis). Sometimes an additional etched K.G. can be found, in this case an extra Mastered By credit can be added.
- Eduard Huis In 'T Veld (1974-1975), signed with E.
- Dirk Huisstede (1990-1992), signed with DH, occasionally just D

-Additional mastering engineers:
- Antoon Kooij (stand-in, ca. 1978-1982), signed with the initial A on one side and K on the other side.
- Keimpe Rozeboom (stand-in), signed with R.
- Sander Bos (trained by Kees Grijpink, ca. 1978-1979), signed with S.

In 1999 the studio was bought by E-Sound Productions B.V. and renamed E-Sound Studio.
