AUDIO QUALITY AND PPM WATERMARKING
RF Signal level is a major component of audio quality and PPM decoding; if there isn’t enough signal then watermarks can’t be decoded, and there are no ratings!
In addition to preforming before and after signal strength measurements, we record the total RF modulation (MPX and sub-carriers), the demodulated audio signals and stereo information. This is used to determine audio quality improvements using subjective algorithms. We also post process the audio signal thru a Telos 25-Seven Systems TVC-15 Watermark Analyzer to display PPM decoding improvements of the MaxxCasting™️ system!
