Audio Precision v4.1Audio Precision has announced v4.1 of its APx500 audio test software, adding enhancements including full input bandwidth across all channels for the two-channel (APx555 and APx525) and 16-channel (APx586) analysers.

Version 4.1 audio test software enables APx555, APx525 and APx586 users to access their system’s maximum input bandwidth across all channels of the test system. For both APx555 and 525 analysers (the latter with option BW52 installed), this means 1MHz of input bandwidth on both channels. With the APx586, v4.1 software enables up to 90kHz of input bandwidth across all 16 channels.

Additional enhancements to the APx software suite include a more flexible choice of filter settings in the signal path, allowing a wider range of cutoff frequencies and improving the user’s ability to fully explore the device under test. Version 4.1 also offers greater control over the Acoustic Response time window, with either auto or manual setting of the window start time and establishment of an absolute time zero for measurement. This enables accurate loudspeaker measurements even in the presence of high-level reflections.

‘These latest enhancements reinforce the power and versatility of AP’s audio test software and our APx Series audio analysers,’ says Audio Precision CEO, Dave Schmoldt. ‘More importantly, each new software release and set of fresh features demonstrates our commitment to our customers and to the advancement of audio test.’
