Audacity is a free, easy-to-use and multilingual audio editor and
recorder. Audacity can record live audio through a microphone or
mixer, or digitize recordings from cassette tapes, vinyl records, or
minidiscs.

A microphone is a bit -iffy. Presumptuous in fact without additional
dedicated gear/hardware other than MB's chipped sound and provision
for a record-jack input. Very often convoluted, expensive, exclusive
and demanding gear/hardware, miles between a reality of sound
recording gear, apart from approaching largely laughable results when
simply plugging in a microphone into a soundcard port.
An imaginable magnitude, say - instead of streaming from CD music by
codecs, directly and accurately to Audacity - recording them directly
from a microphone directed to speakers and an amp for generating aural
transduction to 'live' sound - ipso facto, without dropping either
dynamic range or frequency interplay bandwidths during the process.
Not easy or easily used and by far when considering what "live"
actually is to a pro and professional recordings.
