OK, thanks to Gerhard for suggesting I upload a sample. What you will hear in this 19mb file. First 2minutes are commercials which sound fine, next several minutes of CNN coverage of an Impeachment trial preview. Full of jerky glitches. After that, back to good sounding commercials, and lastly again several seconds of glitchy CNN. Please download this from https://hubert-humphrey.com/cnn-audio-02112021.aac I really hope some1 can suggest a tool to clean this up. Thanks so much in advance Chime _______________________________________________ Linux-audio-user mailing list Linux-audio-user(a)lists.linuxaudio.org https://lists.linuxaudio.org/listinfo/linux-audio-user
