As a college student, I've considered recording lectures, but have never done that for two reasons: overhead and referencing.
How much time did it take you per lecture just to clean up the audio recording? My guess is 10-15 mins. The way I see it is that it's not a lot in general, but if you factor in the cost of context switching, it can become a time sink.
Then, as you noted, there's the task of writing a pseudo-transcript to make later referencing easier. Without it, the audio is completely useless in my view. But there's a trade-off here between granularity and effort required to set it up.
I might still give it a go though, just to see if I can manage it for more than a few weeks. I get distracted easily :(
- JTxt 11y agoIt took a few minutes to process it in Audacity- more the first time while I figured it out. - Select a pause in the recording. - Effect -> Noise removal, get noise profile - Select everything. - Effect -> Noise removal - Effect -> Change tempo, 100% change? (don't remember exactly, but whatever is still understandable/not boring to you, try on a smaller chunk before processing everything.) - Effect -> Truncate Silence. (don't remember what settings I used, but to your taste.) ... Then manually trimming out repeats, useless questions, extra stuff took some time... it was also how I studied. Then more so by playing it back and fixing my notes. I first picked Audionote (android and ios) because typed text is time-coded, so you can skip to that part of the recording by tapping on the text. But I ended up not really using that feature and using it as a dumb recorder and text editor. It did a good job of automatically adjusting the sound level though. (Compressor. You can also do this in Audacity.) Also it was nice that I could have the mic (at the bottom of the iphone) pointed at the prof, and the screen turned 180 degrees facing me. ... I wish there was a better tool that: - During playback, skips pauses. (by audio level threshold.) then easily pick more areas in the recording to skip. (Please just non-destructive editing/filtering though; just build a list of times to skip during playback.) - High quality time compression playback. Variable, even up to 3x perhaps. (without increasing the pitch like audionote.) - AND synced the notes with the recording. - (Even better would be for reliable voice to text, and automatic trimming/outlining... but at some point it may deter grey matter processing.) Perhaps there are better tools now?
- JTxt 11y agoAlso, I think it helps that I'm writing/reading/editing and listening. multi-sensory. Perhaps it could be better by adding video, smelling, tasting, and feeling... :) But no, just capturing the exact words, and being able to trim to what's needed helped me.
- reledi 11y agoThere's also a third reason. It can be illegal without consent of those involved (e.g. lecturer, students, university). To comply with the law, you would have to clear rights such as copyright, performer's rights, moral rights, and privacy rights before any recording takes place.
- JTxt 11y agoYes, great point. I did ask permission before the class. I was not allowed to offer the recordings to everyone, and I took them down after the class.
