For 50 years, RTW from Cologne has accompanied the steady technological progress in the pro-audio industry with innovative instruments and technologies for visual audio monitoring in broadcast, production, post-production, and quality control. Whether audio metering, loudness metering, or signal monitoring, RTW’s state-of-the-art systems are the result of a future-oriented strategic approach that focuses on continuous development while putting maximum attention to reliability and protecting their clients' investments.

RTW has also made significant contributions to the introduction of mandatory standards for loudness metering and control: They not only offer the right products that allow the pro-audio industry to meet current and future standards but also have actively co-developed those standards themselves. Michael Kahsnitz, head of product management at RTW, is a member of the EBU’s PLOUD group that has developed binding loudness-management standards.
