Version 2.3.2—the first major field update since version 2.0 was released last year—is free, reinforcing 25-Seven’s commitment to customers seeking optimal watermarking system performance.Voltair.jpg
“Stations want to ensure that their watermark encoding is as good as it can be, and Voltair offers visibility and enhancement tools found nowhere else,” says Geoff Steadman, Founder of 25-Seven. “Voltair is still making a positive difference in registering meter count and overall watermarking performance, even in this post-eCBET world. Not only are we confident this is so, we see our users doing their own research and arriving at the same conclusion, while they continue to invest in Voltair technology.”
A major operator’s manual revision is part of the update, with new sections devoted to use of Voltair in conjunction with the Omnia.9 and Omnia.11 processor patch points for optimal processing performance. In addition to considerable "under the hood" improvements, Version 2.3.2 adds two significant new features: Encoder Distortion Testing and Display and Flexible Program Output.
As part of its calibration process, Voltair has always measured the level of distortion generated by the attached watermarking encoder. Over the years, 25-Seven has discovered that some encoders, even when not actually adding watermark tones, may add noise or distortion to the audio signal. If this distortion is too high, Voltair will refuse to calibrate to the encoder. Since the calibration data in 25-Seven’s system logs provides information about signal health of individual encoders, the company decided to turn its field experience into a diagnostic feature. Firmware 2.3.2 adds a new “Calibration” section to the external web Information page that shows the results of this distortion testing, which can be useful for detecting encoders whose audio path may be distorting a station’s feed.
