2700 Series Windows APIB Drivers v1.0
Audio Precision's proprietary APIB interface bus requires the installation of the proper Windows driver software on your PC.
2700 & ATS-2 Resources Disc
The Audio Precision Resources Disc contains Sample Tests, the Performance Check and documentation to help you operate your AP2700 or ATS control software compatible audio analyzer. AP2700 or ATS control software is required. The installer includes both AP2700 and ATS-2 resources. You will be prompted to choose which components you wish to install.

ATS-2 Add-ins v1.60
Add-Ins are additional software features that can be seamlessly integrated into the ATS-2 user interface. AP uses the standard Windows "Add/Remove Programs" exclusively to manage Add-Ins. Add-In Descriptions User Preferences -- Provides a user interface where you can set user preferences, define multiple preference groups and control how the preferences are applied to tests. Document Test Settings -- Creates an ASCII text file that documents selected panel settings for the current test configuration. Delete Traces -- Provides the capability to delete selected traces from the Graph / Data Editor. Sweeps that have any traces removed from view in the Graph are deleted.

TechNotes/AppNotes
Technote 28: Measurement Microphone dBspl Calibration
This TechNote describes how to set up and use the dBr unit as dBspl. Automated AP Basic macros (procedures) are available to facilitate the calibration. These macros apply to the instrument analog analyzers. Additionally, two computational methods are described to help you understand the macros, and to help you calibrate a measurement microphone without the macros.
Technote 20: Return Loss Measurements
This Technote gives an overview of the concept of return loss in telephony. Return loss is an expression of the impedance mismatch in a transmission circuit which can give rise to reflection of signal energy. Sample hybrid circuits and their use in return loss measurements using Audio Precision instruments are described.
Legacy Material
Appnote 1: CD & DVD Player Tests using System One or System Two vN/A
This expansion and revision of the original Audio Precision Compact Disc Player Testing Application Note (AN-1) includes many new test techniques as well as refinements and improvements on the original tests. Test and procedure files supplied with this application note provide new convenience and ease-of-use for testing CD players using these instruments. Files created for both System One and System Two using APWIN are available. Also included are specialized and difficult tests such as distortion at low amplitudes, decoder linearity measured to below the Least Significant Bit, quantization noise, dynamic range, SMPTE and twin-tone (CCIF) intermodulation distortion and Wow and Flutter as an impulse noise test.
Books
Measurement Techniques for Digital Audio v1
Much has been written about digital audio, its defining standards, the ever-changing hardware and software, the various applications in recording and broadcasting and telecommunications and the audibility of this or that configuration or artifact. In this book the late Julian Dunn focused instead on the measurement of digital audio signals, and examined in great detail techniques to evaluate the performance of the converters and interface through which the audio passes.
The Audio Measurement Handbook v1
This reference handbook is a practical, hands-on guide for workers in all phases of the audio field. It covers basic tools and techniques, common environments for audio testing, application of these techniques to common audio devices, the typical ranges of performance to expect in different devices, and a glossary of terms and key specifications used in audio measurement. 178 pages Written by Bob Metzler.
Whitepapers
Fundamentals of Modern Audio Measurement vN/A
Characterizing professional and consumer audio equipment requires techniques which often differ from those used to characterize other types of equipment. Sometimes this is due to the higher performance requirements. Other times it is due to the peculiarities of the audio industry. Other fields deal with some of the same measurements as those in audio. From level and THD to jitter and noise modulation, no other field has the breadth of requirements found in high performance audio.
