I am recording my sleep and have ca. 8 hours of recording per day. Recording only upon voice activation has a too high thresdhold I cannot change in the digital recorder, so I cannot use this. Now I cannot listen to 8 hours of sleep multiplied by xx days.
Audacity came to my mind as first stop.
Is there some Plugin or tool I can use:
to find sound, label it (the Silence/Sound Finder)?
to read timestamp and calculate the current time right before next dream, log to a file
(later if possible: record the timestamp as sound and insert in audio, too)
Sound Finder might be able to do the job, but it may have the same problem as the voice activation on the recorder - false positives from non-speech noises. You’ll have to experiment to find the right settings.
Audacity does not record time stamps, so you’ll have to use the time line and know when the recording was started.
Once you have all the talking segments labelled you can do File > Export Labels, then bring the resulting text file into a spreadsheet.
There’s no way I know of to automate this process in Audacity.
An automatic solution would be “truncate silence” which would remove all the recording which was below a threshold : cutting out the boring “silence” (“silence” = sound below user set threshold). However I’ve never used “truncate silence” on a recording which was more than a few minutes long. The time line would be lost after “truncate silence” : you would not know when the somniloquy occurred.
Just tried Audacity “truncate silence” on a 5hour 15min mp3 (sample rate 22050Hz)
It managed it in eight minutes, and reduced its length to under an hour ,
so my guesstimate of 10 -15 minutes for 8 hours seems about right.
