Audio test software enhances analyser performance
Audio Precision has released version 4.1, of its APx500 audio test software. It provides enhancements, including full input bandwidth across all channels for their two-channel (APx555 and APx525) and sixteen-channel (APx586) analysers. Version 4.1 of the APx500 audio test software enables users of the APx555, APx525 and APx586 audio analysers 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 1 MHz of input bandwidth on both channels. With regards to the APx586, v4.1 software enables up to 90 kHz of input bandwidth across all sixteen 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 users 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.
