Audio Precision Celebrates 30th Anniversary with Public Debut of APx555 Audio Analyzer

Created on 10 Oct 24

New test system offers industry-leading performance, flexible software and a broad range of digital I/O

AES Convention, Los Angeles, October 10, 2014: Audio Precision, the recognized standard in audio test, marked its 30th year in business today with the public debut of its new high-performance audio analyzer and the commencement of the 137th International AES Convention. The APx555 outperforms the legendary Audio Precision 2700 Series, the previous leader in analog audio performance, and delivers improved flexibility, automation and ease-of-use for developers of audio components, equipment and systems.

Unmatched analog performance

With a typical residual THD+N of -120 dB (conservatively specified at -117 dB), the two analog channels of the APx555 boast the lowest noise and distortion of any audio analyzer ever made, allowing the most sensitive measurements to be made with assurance. This extraordinary performance is coupled with up to 1 MHz bandwidth and FFT resolution of 1.2 million points across all channels. The generator is capable of producing low distortion sine wave signals up to 204 kHz, at high-level amplitudes
up to 26 Vrms.

30 Years of Audio Test & Measurement Leadership

Audio Precision revolutionized the audio test world thirty years ago with the introduction of System One, the first audio analyzer to utilize the power of a PC as part of its design. AP continued to lead the industry as new audio technologies were developed: dual-domain audio analysis, 192K digital analysis, Dolby and DTS test solutions, and more recently with the next-generation APx platform, offering the first multichannel audio analyzer and the first HDMI audio analyzer. The APx series also introduced a modular architecture to enable a wide range of digital I/O and the ability to evolve with the changing needs of audio professionals around the world.

“As we enter our fourth decade, we are honored to be an integral part of the audio industry,” says AP co-founder and Chief Analog Designer, Bruce Hofer. “We look forward to continuing to push performance boundaries to help audio engineers and technicians deliver the best possible audio experience to listeners everywhere.”
