0:00.0 | I was always just thinking that this file system would save me. I just thought like well, I'll just |
0:04.1 | I'll stick it out and nobody knew file system here probably next year and I would think in that for a lot of years now. |
0:11.6 | Well, I spent this morning trying to parallelize the lame MP3 encoder. Why? Why not? |
0:18.8 | Yeah. Because it's a very hard problem that hasn't been solved since like the early 2000s. |
0:22.8 | And I often need to encode our show MP3 which takes probably I don't know 90 seconds to encode. |
0:30.8 | It's it's a surprisingly long time for a modern computing task like that and that annoys me. |
0:37.3 | And so I figured why don't I spend the afternoon seeing if I can parallelize the the MP3 encoder and |
0:43.6 | I have and there are faster encoders than the lame encoder and I know |
0:49.0 | This is hard for me to talk about because I know that the word lame is really not a nice word to say |
0:55.5 | but it's kind of like the like the Gimp photo editor like also not a nice word to say |
1:00.7 | and for whatever reason these open source projects name themselves these acronyms without regard to what those |
1:05.1 | words mean and how they hurt people. So I'm sorry I'm advanced but it's called the lame MP3 encoder |
1:10.9 | and it is I have tested many different encoding options for podcast audio from MP3 AAC the |
1:18.0 | HE AAC all like the the MP3 pro like all like the the add-on like spectral |
1:23.6 | things to these formats and |
1:26.8 | simple joint stereo with the lame MP3 encoder is by far the the highest quality |
1:31.5 | and at the best bit rates that I have that I have found. It's really it's really quite good. So |
1:36.1 | problem is MP3 encoding is very difficult to parallelize at least while also doing it well. |
1:42.7 | And so that's what I'm kind of trying to do here. |
1:45.3 | Just for ATP. Well I mean ideally I would you know ship this to other people as well you know maybe |
1:50.8 | open source it or maybe just you know embedded into my pre-production tool that I have to at some |
1:55.6 | point hopefully maybe release so it could it could be very helpful because one of the problems is |
