Thanks

19kHz tone is used by the FM transmission system in the US to alert the receivers to decode the mux into two channel stereo.
But why is above 19kHz nothing cut? Btw the freq is from a dat recording thats why i find it strange. My first thought the mp3 file was re-recorded with a md and then converted to flac
