LYNX YELLOBRIK DIALOGUE CLEANERS

Lynx Yellobrik IDC 1411 is a hardware solution for enhancing speech. Based on the Audionamix Instant Dialogue Cleaner software plugin IDC 1411 can be applied to parallel production of content for hearing impaired viewers, or to improve the production of automated closed captions with clearer audio.

IDC 1411 has been designed by Lynx to process uncompressed SDI video formats via BNC or fibre, and AES based audio via BNC. When a USB connection is made between module and LynxCentraal or yelloGUI, the default parameters can be changed. SDI Output can also be routed to fibre or BNC, and additional audio filtering including Audionamix IDC, two sequential equalizers, and a compressor can be applied.

The module’s instant dialogue cleaning audio filter is based on the plugin developed by Audionamix to provide a hardware-based solution that works independently of software in real time with minimal delay. Powered by a deep neural network that separates and preserves speech in real time the user is able apply -66.3 to +18db gain to speech and background separately. This allows the user to remove background interference without compromising integrity of the dialogue. The ‘strength’ parameter allows you to slightly modify what is identified as speech and respectively as noise. For a more ‘aggressive’ setting whereby more content will be identified as noise, the ‘strength’ and be increased. Dialogue cleaner can be enabled separately from the other functions including equalizers or compressor. If the audio signal needs to be increased or reduced after this process, a master gain is available as IDC Output Gain, which can be enabled separately.

Two fully parametric peak/notch equalizers are provided which are applied in series. Both equalizers provide parameters for the centre frequency 20Hz to 20kHz, gain, and Q at 0.3 to 50 to control the bandwidth. Equalizers can be enabled separately from the other functions like the dialogue cleaner or the compressor. If the audio signal needs to be increased or reduced after this process, a master gain is available as EQ output gain, which can be enabled separately. A hard-knee, peak-sensing, stereo-linked audio compressor is provided with parameters for threshold, ratio, attack, and release.

IDC1411 processes one stereo audio channel, which can be freely configured to be sourced either from one of the SDI inputs embedded stereo channels or from AES input. The AES output will always contain the processed stereo audio channel. Additionally, one of the SDI output’s embedded audio channels can be overwritten by the processed stereo audio channel.

The module is suitable for all SMPTE standard signals conforming to SMPTE 292M, 424M, and 2082 (1.5Gbit/s, 3Gbit/s, and 12Gbit/s)
