but also our recording devices and the whole bluetooth sound system are rather modest) we now want to improve the listening quality of our recorded lectures ( <https://www.youtube.com/@xxxxxxxx> https://www.youtube.com/@xxxxxxxx; last years' lectures were added under a more general academic youtube account of ours, <https://www.youtube.com/@xxxxxxxx> https://www.youtube.com/@xxxxxxxx). a colleague brought these programs to our attention, * https://flixier.com/tools/audio-enhancer * https://www.kapwing.com/tools/audio-editor/audio-enhancer * https://www.geeksforgeeks.org/top-free-video-audio-enhancer-tools/ * https://www.canva.com/features/audio-enhancer/ * https://voice.ai/tools/audio-enhancer however, I understand that these can only be used once the videos are uploaded. what we need though is a way to do the cleaning beforehand (each video recording is about 17-35GB in size). another supporter offered to do it on adobe premiere and the results were indeed great in terms of speaker clarity, however this time, the timbre of the speaker had quite changed. :) some of them are well-known scholars, hence such major changes in voice character feels really alienating. so we are stuck now. is there anything you can suggest us? many thanks, esra Esra Mungan, PhD Associate Professor (left Bogazici University since Dec. 2024) <https://psychology.bogazici.edu.tr/content/esra-mungan> https://psychology.bogazici.edu.tr/content/esra-mungan (TK/EN) <https://universitybogazici.wordpress.com/> https://universitybogazici.wordpress.com/ (TK/EN) <https://direnenakademi.wordpress.com/> https://direnenakademi.wordpress.com/ (TK) ------=_NextPart_000_0021_01DBAA25.691160A0 Content-Type: text/html;
