NTi Audio

NTi Audio AG is a specialist test-and-measurement company headquartered in Schaan, Liechtenstein. Its products are used to measure, generate, analyze, and validate audio and acoustic signals in professional audio, manufacturing, research, service, building acoustics, public-address systems, and other noise-control applications. The company is particularly associated with portable audio analyzers, sound-level meters, acoustic measurement systems, signal generators, and automated production-test equipment. The business was established in March 2000 through a management buyout of the Audio Measurement Division of Neutrik AG. Its technical lineage reaches further back: Neutrik’s test-and-measurement department introduced the AudioTracer frequency-response chart recorder in 1977, followed by the modular AudioGraph instruments in 1983. Stand-alone A1 and A2 analyzer families were added in 1991 and 1994. In 1996, the Rapid-Test family extended the portfolio into fast, multitone production testing, including applications associated with mobile-phone manufacturing. The company’s early product development therefore combined laboratory audio measurement with the needs of industrial quality control. NTi Audio’s initial post-separation portfolio included the Minirator MR-1 handheld signal generator, introduced in 1999, as well as the ML1 handheld audio analyzer, AL1 sound-level and acoustic analyzer, and DL1 digital audio analyzer. These instruments were aimed at audio professionals, educators, installers, and service technicians. The company also developed software and production-test solutions, including the PureSound extension for the Rapid-Test RT-2M dual-channel multitone audio-frequency analyzer, which supported loudspeaker testing. Between 2006 and 2010, NTi Audio expanded its portable EXEL family. This generation included the XL2 Sound Level Meter, also marketed as an Audio and Acoustic Analyzer; the Minirator MR2 and MR-PRO audio generators; the Digirator DR2 digital audio signal generator; and the TalkBox acoustic generator used as a reference for speech-transmission-index testing. These products strengthened the company’s position in field measurement, installed-sound verification, acoustic analysis, and professional audio troubleshooting. In 2009, after nine years of operation, the company changed its legal name from NTI AG to NTi Audio AG, reflecting the expansion of the New Technologies in Audio identity. In 2011, it introduced the FLEXUS FX100 Audio Analyzer for research and development laboratories, service work, and production environments. In 2022, NTi Audio added the XL3 Sound Level Meter, described as a networked Class 1 sound-level meter, extending the portfolio toward connected professional noise and acoustic measurement. NTi Audio develops and markets its products from Schaan. Electronic printed-circuit-board manufacturing is outsourced to Swiss manufacturers, while the company maintains subsidiaries in the United States, China, Japan, South Korea, the Czech Republic, the United Kingdom, France, and Germany. Sales partners extend its reach to more than 50 countries. The company is also affiliated with professional and industry organizations including the Audio Engineering Society, the International Institute of Noise Control Engineering, the Association of Loudspeaker Manufacturing & Acoustics International, the Swiss Society of Acoustics, the Liechtenstein Chamber of Commerce, and Switzerland’s association for electrical engineering, power, and information technologies.

NTi Audio’s history derives from the audio test-and-measurement activities of Neutrik AG. In 1977, Neutrik’s test-and-measurement department introduced the AudioTracer frequency-response chart recorder. The modular AudioGraph series followed in 1983, establishing an early platform for systematic audio characterization. Stand-alone A1 and A2 analyzer families were subsequently introduced in 1991 and 1994. The company moved further into automated industrial testing in 1996 with the Rapid-Test family. These multitone analyzers were designed for fast production tests and included applications for the mobile-phone industry. Their IEEE 488.2 GPIB interfaces and software developed with National Instruments LabWindows/CVI supported integration into automated test environments. This production orientation became an enduring part of the company’s identity alongside its laboratory and field instruments. A handheld product direction emerged with the Minirator MR-1 signal generator in 1999. The ML1 handheld audio analyzer, AL1 sound-level and acoustic analyzer, and DL1 digital audio analyzer followed, broadening the offering for professional audio users, educators, installers, and service personnel. In March 2000, the Audio Measurement Division of Neutrik AG was separated through a management buyout, creating the independent NTI AG business. The company continued developing software and production-test applications. PureSound was offered as a software extension for the Rapid-Test RT-2M dual-channel multitone audio-frequency analyzer, supporting loudspeaker test workflows. From 2006 to 2010, NTi Audio introduced the EXEL generation of handheld equipment: the XL2 Sound Level Meter, Minirator MR2 and MR-PRO generators, the Digirator DR2 digital signal generator, and the TalkBox acoustic generator used as a speech-transmission-index reference. After nine years of operation, NTI AG changed its name to NTi Audio AG in 2009. The revised name emphasized the company’s New Technologies in Audio identity and its specialization in professional audio and acoustic instrumentation. In 2011, the company launched the FLEXUS FX100 Audio Analyzer for research, development, service, and production applications. The FX100 represented a continued effort to serve customers across the full product lifecycle, from engineering design through manufacturing and field maintenance. In 2022, NTi Audio released the XL3 Sound Level Meter, described as a networked Class 1 instrument. This extended the company’s portable measurement range into connected professional sound-level monitoring and acoustic work. NTi Audio currently develops and markets its products from Schaan, while electronic printed-circuit-board production is outsourced to Swiss manufacturers. Its international organization includes subsidiaries in the United States, China, Japan, South Korea, the Czech Republic, the United Kingdom, France, and Germany, supplemented by sales partners in more than 50 countries. The company participates in several professional and trade organizations, including the Liechtenstein Chamber of Commerce, the Audio Engineering Society, the International Institute of Noise Control Engineering, the Association of Loudspeaker Manufacturing & Acoustics International, the Swiss Society of Acoustics, and Switzerland’s association for electrical engineering, power, and information technologies. These affiliations reflect its position at the intersection of professional audio, acoustics, industrial quality control, and noise measurement.
