💖 pcmmix — PCM mixer 💖

okay bestie, so this is pcmmix(1) from the hxtools collection, and it's literally the cutest little audio-blender you've ever met. she takes two or more input streams and mixes them together. that's it, that's the job, and she eats every time. ✨

🌸 SYNTAX 🌸

pcmmix [-ap] [-t p/q] file...

yeah that's the whole thing. give her some files, she gives you a blend. 🫶

🎀 DESCRIPTION 🎀

so here's the tea: pcmmix will mix two or more input streams together. those streams are assumed to be LE16 PCM, and they gotta have the same number of channels — no mismatched-channels nonsense in this house, okay? 🙈

and she's flexible about how she mixes, because she can do it in either arpeggiated mode or polyphonic mode. two whole vibes, one tiny tool. main character energy fr fr. 👑

✨ OPTIONS ✨

  • -a — select arpeggio mode. 🎹 little sparkly notes hopping around one at a time.
  • -p — select polyphony mode. 🎶 everybody plays at once, all together, no waiting.
  • -r rate — input sample rate. the default is 48000. ⏱️
  • -t p/q — this one defines the length of one arpeggio block, and inside that block, data from all the input sources gets round-robined. you give it as p/q seconds. the default is 80/1086. 💅
ngl the -t thing is the spicy one — that fraction is literally controlling how long each source gets to shine before the next one steals the aux cord. 🔥

🍓 EXAMPLES 🍓

  1. Entertainer from FOG:
pcmmix -t 160/1086 <(bsvplay --pianoman entrtan1.mus) <(bsvplay --pianoman entrtan2.mus) <(bsvplay --pianoman entrtan3.mus) <(bsvplay --pianoman entrtan4.mus) | aplay -fcd -r48000 -c1
  1. IHOLD from FOG:
pcmmix -t 80/1086 <(bsvplay --pianoman ihold1.mus) <(bsvplay --pianoman ihold2.mus) <(bsvplay --pianoman ihold3.mus) <(bsvplay --pianoman ihold4.mus) | aplay -fcd -r48000 -c1

see how she's using process substitution to feed her four streams at once? iconic. no temp files, no mess, just vibes. 🦋
