Script: Audio-only version of the SICP lectures

I'm about to take a road trip to Chicago to attend two of David Beazley's courses, and in preparation I wanted to listen to the original SICP lectures while driving.

Here's a pair of scripts which will download the lectures and then extract just the audio into AAC files.

You will need to brew install ffmpeg id3v2 or apt-get install ffmpeg id3v2.

get-lectures.sh

#!/bin/bash

set -e

for i in 1a 1b 2a 2b 3a 3b 4a 4b 5a 5b 6a 6b 7a 7b 8a 8b 9a 9b 10a 10b
do
    wget http://www.archive.org/download/MIT_Structure_of_Computer_Programs_1986/lec${i}.mp4
done

make-audio.sh

#!/bin/bash

set -e

track=1
for i in 1a 1b 2a 2b 3a 3b 4a 4b 5a 5b 6a 6b 7a 7b 8a 8b 9a 9b 10a 10b
do
    ffmpeg -i lec${i}.mp4 -vn -acodec copy lec${i}.m4a
done
