Dynamic Digital Audio Levelling (Award winning)
Appear TV’s Audio Leveling solution enables operators to equalize the audio level of both TV and radio channels originating from various studios, processed with different encoders. This solution lets operators tune the audio level of up to 250 audio tracks individually, within the MPEG domain. The Audio Leveling module supports MPEG-1 layer 1 or 2 audio with an adjustment range of +/- 30 dB.

The proposed solution simplifies the process of equalizing the audio levels of hundreds of channels by eliminating the need to decode and re-encode these TV and radio channels prior to transmitting them.
