### 16 bit vs 24 bit

|
|
think it is unlikely that an otherwise reasonably capable DAW computer
|
|
would bottleneck due to recording at 24-bit instead of 16-bit. Reaper
|
|
and all modern DAWs use high-precision audio engines over 24-bit, so
|
|
your samples are being processed at high bit depths even if they are
|
|
low-resolution samples. A second fast hard drive is pretty cheap in the
|
|
scheme of things and almost a requirement for high-track-count audio, it
|
|
seems to me. Moreover, 24-bit is stupidly cheap and easy insurance
|
|
against the single biggest headache of digital recording, namely trying
|
|
to set the record levels high enough without clipping. With 16 bit, if
|
|
you need to leave 24dB headroom above the aver- age level for a singer
|
|
with no mic technique, then you\'re really only recording at about 12
|
|
bits resolution on average. The whole point of 24 bit is that you no
|
|
longer have to record close to zero, you could record with peak levels
|
|
of like -50 and still have CD-quality resolution. So you can leave
|
|
plenty of headroom and just turn down the input gain as low as you want
|
|
-- no fear of clipping, and no worries of lost resolution, no matter how
|
|
"wild" the singer. Sample rate is a whole different thing, OTOH. Working
|
|
at higher sample rates def- initely affects performance.* [^1]
