Neat project. Reminds me of the concept of streaming a log file through some kind of tokenizer -> tone generator (probably doesn't work for really busy programs) so that you can listen to the program execution and pick out things like errors from jarring notes. Don't remember where I came across that concept though :(
You can listen to any file in Audacity with Import > Raw Data, where it assigns each byte in the file one "point" in the audio waveform (depending on which format you select).
Would be interesting to make it more human "readable" though by extracting out tokens and assigning tones to them. Did you mean that something like that exists already?
I heard someone on HN say that back in the day when computers were big and noisy you could tell from the sound whether or not your algorithm was working properly, had gotten in an infinite loop etc...
I know I've come across the concept before, but I don't know if it was an actual product/bit of software. I think the Audacity approach would just sound like static; though without trying it, that's just idle speculation.
For Glog formatted logs, you could probably just extract the first letter (E/I/V/etc) and play tones for those. For anything else.. well, I suppose the idea is not "make music" but "expose patterns", so if you can derive the patterns for the log entries, then you could assign tones to each pattern (instead of each token in the line).
