I have one of many utilities for extracting the audio from video clips
(Pazera Free Audio Extractor); one of the options it offers is "Try
extract original audio stream" [sic].

I would like to use this, on the principle of doing as few conversions
as possible. (Many extractors do not make it clear whether they are
doing, or are recoding the audio; often they offer selectable sample
data rates, or sample rates, or file size, which obviously mean they
_do_ do an extra conversion stage.)

Mostly - possibly always, but that could be because most of the video
files I'm extracting from are .mp4 - it produces a .m4a audio file. My
old .mp3 player (actually it's a SatNav, but can be a .mp3 player too)
doesn't know .m4a. (Nor does the old [bought!] version of GoldWave I
use, but I can always get into that by having Pazera extract as .wav,
which though a conversion, I presume doesn't involve any loss.)

So: _does_ .m4a contain the same samples as .mp3 but with different
wrapper, or are they different? (If they are the same, anyone know an
audio extractor that extracts original [i. e. without conversion loss]
to .mp3?)

I use a lot of FLAC files.Â*Â* Mp3 loses a lot in translation.

Storage is so cheap these days WAV is not that far out of reach and
that is about as good as sound gets if CD is the gold standard.
