[linrad] Re: 16 or 24 bits ?

Alberto:

As with all such things, the answer depends.  Your applications, such as
Spectran
are primarily intended to listen to output of a radio.  These radios audio
circuits
have very little real dynamic range.  As such,  your 24 bit sound card is a
waste.

If the application we are talking about is SDRadio, you will definitely
benefit
from the use of 24 bits by matching the available dynamic range in the radio
to
that available from the sound card.  If the noise floor of the radio and
card
are close, this will give you your best strong signal handling capability by
having a large sound card dynamic range.

Subject: [linrad] 16 or 24 bits ?


A question to you all users of Linrad. With the proper sound card
Linrad allows the user to choose between 16 or 24 bits of amplitude
resolution. My question is : have you noticed situations where having
24-bit resolution gave you some benefits ? I am asking as I am planning
to add 24-bit support to one of my programs, but don't want to waste
my time for a feature that then nobody will activate, being useless.
Theoretically you should gain some dBs of dynamic range, depending
on the quality of the sound card, but I would like to hear from practical
experiences "on the field" .. :-)

Thanks for any answers,

P.S. Happy Easter to the Catholics among you.
