💖 oggdec — the girlies' guide to un-squishing your Vorbis files 💖

okay so welcome to oggdec(1), part of the Vorbis Tools family 🎀 this is the page where we learn how to turn Ogg Vorbis into boring-but-useful PCM audio. grab a snack, bestie, we're decoding 🍓

✨ NAME ✨

oggdec — simple decoder, Ogg Vorbis file to PCM audio file (Wave or RAW).

✨ SYNOPSIS ✨

oggdec [ -Qhv ] [ -b bits_per_sample ] [ -e endianness ] [ -R ] [ -s
signedness ] [ -o outputfile ] file ...

✨ DESCRIPTION ✨

so basically oggdec takes your Ogg Vorbis files and decodes them into PCM-encoded ("uncompressed") audio files — either Wave or RAW format. it's giving decompression era 💅

for each input file, oggdec writes to a filename based on the input filename, but with the extension changed to .wav or .raw as appropriate. no cap, it just handles the naming for you 🫶

if the input file is specified as -, then oggdec will read from stdin, and write to stdout unless an output filename is specified. likewise, an output filename of - will cause output to be to stdout. pipes? iconic. 🦋

Writing Wave format to stdout is a bad idea. Wave requires a seekable medium for the header to be rewritten after all the data is written out; stdout is not seekable. so like… don't do that, bestie 😭 it literally cannot work.

✨ OPTIONS ✨

• -Q, --quiet — suppresses program output. shhh 🤫 no yapping.
• -h, --help — print help message. your little built-in bestie.
• -V, --version — display version information.
• -b n, --bits=n — bits per sample. valid values are 8 or 16. that's it, that's the whole list 🔥
• -e n, --endian=n — set endianness for 16-bit output. 0 (default) is little-endian (Intel byte order). 1 is big-endian (sane byte order). yes the manpage really did say "sane byte order," we stan a petty legend 💀
• -R, --raw — output in raw format. if not specified, writes Wave file (RIFF headers).
• -s n, --sign=n — set signedness for output. 0 for unsigned, 1 (default) for signed.
• -o filename, --output=filename — write output to specified filename. this option is only valid if one input [file] is specified, or if raw mode is used. don't get cute with it 💅

✨ EXAMPLES ✨

🎀 decode a file enabler.ogg to enabler.wav as little-endian signed 16-bit (default options):

oggdec enabler.ogg

🎀 decode a file enabler.ogg to enabler.raw as headerless little-endian signed 16-bit:

oggdec --raw enabler.ogg

🎀 decode enabler.ogg to enabler.crazymonkey as unsigned 8-bit:

oggdec -b 8 -s 0 -o enabler.crazymonkey enabler.ogg

not the .crazymonkey extension 😭 the manpage said it, not me. we respect the lore.

🎀 decode enabler.ogg to enabler.raw as big-endian signed 16-bit (any of the following):

oggdec -R -e 1 -b 16 enabler.ogg
oggdec -R -e 1 -b 16 -o enabler.raw - < enabler.ogg
oggdec -R -e 1 -b 16 - < enabler.ogg > enabler.raw

three whole ways to do the same thing, and every single one ate ✨

🎀 mass decoding (foo.ogg to foo.wav, bar.ogg to bar.wav, quux.ogg to quux.wav, etc.):

oggdec *.ogg

the glob is doing all the heavy lifting and honestly? main character energy 👑
