🌸 spa-resample(1) — the girlies' guide to the PipeWire resampler 🌸

okay so welcome to spa-resample(1), from the General Commands Manual bestie, you're gonna love her 💖

✨ NAME ✨

spa-resample — the PipeWire resampler debugging utility 🎀 like, she exists to debug the resampler, that's her whole thing, no cap

🦋 SYNOPSIS 🦋

spa-resample [OPTIONS] INFILE OUTFILE

💅 DESCRIPTION 💅

So basically: use the PipeWire resampler to resample INFILE into OUTFILE, following whatever options you gave her. Slay. ✨

And like… that's literally it. This is useful only for testing the resampler 🔥 she's a debugging queen, not a main-character audio tool, iykyk. Don't come for me, that's just what the manpage says, fr fr.

👑 OPTIONS 👑

  • -r RATE, --rate=RATE — sets the output sample rate, periodt 🎵
  • -f FORMAT, --format=FORMAT — sets the output sample format, and your options are s8 | s16 | s32 | f32 | f64 (pick one bestie, not all of them 🙈)
  • -q QUALITY, --quality=QUALITY — the resampler output quality, and it goes from 0-14 — yes, fourteen whole levels of quality, she's highkey thorough 💜
  • -c FLAGS, --cpuflags=FLAGS — cpuflags moment 💀 see spa/support/cpu.h for the details, that's where the lore lives
  • -h — show help 🫶 use her, she's there for you
  • -v — verbose operation 🔍 so you can watch everything happen in real time, obsessed

🌈 EXAMPLES 🌈

here's the iconic one, look at her go:

spa-resample -r 48000 -f s32 in.wav out.wav

48000 Hz, s32 format, in.wav goes in, out.wav comes out. ate and left no crumbs ⭐
