Presently I use the built in audio-graph visualiser in QuickTime on macOS to analyse my recordings. However, it takes a long time to filter through everything and so I am looking for something more advanced. [IMG]https://www.audiosciencereview.com/forum/index.php?attachments/screen-shot-2023-08-13-at-22-43-25-png.305645/[/IMG] I am looking for some open source software that can help me speed up my analysis in two ways: 1/ Set the time of the recording from the beginning so that any portion I cut away will automatically know what the relative timestamp would be and then insert that (regex style) into the filename. 2/ From a sample fed in automatically search for a specific sound e.g. a person's voice, a bird, washing machine... so that I don't have to manually sift through everything. If possible I would like something open source, but any suggestion will do. Forget not that I live in the macOS world, so cannot use anything on Windows.
