AP - The Recognized Standard In Audio Test


Audio Precision is accredited by the American Association for Laboratory Accreditation under ISO/IEC 17025:2005 for equipment calibration at our main factory in the USA. Calibration has been requested by many of our customers who need to use calibrated audio test instruments to meet their own Quality System Requirements.

Calibration provides documented and traceable verification that instruments meet or exceed all of their published specifications. Accredited calibration adds a further degree of rigor to the calibration process, incorporating review and On-Site Assessment by recognized independent experts. With its 17025 accreditation, AP meets the highest standard of calibration performance.

  • All new audio analyzers sold by AP include an Accredited Calibration when shipped from the Factory.
  • AP offers Accredited Calibration of existing AP audio analyzers as part of our Service Offerings (Service B).
