| do2kd | Hallo . i look for help. i try to filter noise out of Shortwave transmissions in real time. Ubuntu studio is installed. all works fine i can say. Jackrack is one of my friends but i have not found the right filters yet. Ideas? Questions, Infos you need? | 19:58 |
|---|---|---|
| zequence | do2kd: If you can determine the approximate frequencies by ear, the usual eq and filter tools should suffice. Not sure if there are any all-in-one plugins for that purpose | 20:19 |
| zequence | I would assume you won't need anything below 100-200hz(depending on voice), and nothing above 7000-10000Hz(also, depending on voice) | 20:21 |
| zequence | If there's a clear hum, like a note, then you will need to use a steep notch with an eq to get that note out. With shortwave radio I don't know about transients. With transients you would need to take care a few as well | 20:22 |
| zequence | If the note is say 100Hz, the natural transients would be 100, 200, 300, 400, and so forth. | 20:23 |
| do2kd | zequence: the transmission has only a bandwidth of 3khz . . so the frequencies max 3000hz. the notch filter i know. my biggest problem are the "noise" from atmospherics / interferences. could you understand it . sorry my mother language is german and english learned 30 years ago :) Thanks or your help | 22:27 |
