The DaySequerra iLM8 Intelligent Loudness Monitor measures perceived loudness of eight channels of program audio using the industry-standard ITU-R BS.1770/1 and DTS Technologies Neural Loudness Measure (NLM) algorithms. The DTS NLM algorithm uses a perceptual model of human hearing to more accurately detect spectral and density differences, inter-channel relationships and temporal overlaps in any audio content, resulting in a more accurate perceived loudness measurement over time.

The iLM8 measures the perceived loudness of eight channels of program audio and displays the results in an easy-to-read numerical format with a moving average over time, eliminating the variations with engineers interpreting traditional VU or PPM indicators (neither of which can measure perceived loudness). Four AES inputs and one HD-SDI input (optional, see ILM8-HDSDI) are provided for simultaneous measurement for 5.1 surround and auxiliary stereo inputs. With the HD/SDI option, eight channels of de-multiplexed SDI audio can be routed to the AES outputs; channel mapping is provided for all 16 SDI audio channels.

To improve system reliability and up-time, the DaySequerra iLM8 uses a robust DSP-based processing platform rather than the PC-based approach used by most other manufacturers to completely avoid broadcast disruptions caused by operating system lockups. The iLM8's built-in high-performance headphone amplifier allows monitoring of any two user-selected outputs even in noisy background environments. An Ethernet interface provides long-term logging and field software updates capability.
