Recently I spent some time finally finishing my DIY DAC and needed some signal generator for digital AES/EBU, coax / spdif audio to test and evaluate it. Turns out sox is pretty handy for that:

sox -r 48000 -n -t alsa spdif synth sine 1000 # square, triangle, sawtooth

Update:

sox infile.wav outfile-left.wav remix 1
sox infile.wav outfile.wav remix 1,2

If sox can not read your macOS recorded file with:

sox FAIL formats: can’t open input file Recodging.aifc: Unsupported AIFC compression type ‘in24′

You can let it use libsndfile to load the file anyway:

sox -t sndfile Recordings.aifc converted.aif

Update 2:

ffmpeg -i movie.mov -vn -acodec copy out.mp2
