=Hi!
=
=I'm running a SPARCstation IPX with SUNOS 4.1.2
=
=My question concerns soundtool.
=
=Why is the reproduction so awful ? I connected a CD played to the sound input
=port, sampled a couple of my favourite tracks with soundtool and saved them
=on disk. No problems.
=
=However, when played back via soundtool they sound dreadful - like a an old fashioned
=transistor radio.
=
=It would be reallly nice to have decent quality sound on disk.
=
=
=I wonder if any of you SUN guru's can tell me why the repro is so bad ?
=
=It occurs to me that it is either:
=
=1. The sample rate is too slow, although 8000 times a second sounds a lot to me.
=   (I rebuilt soundtool with the #define governing the sample rate set to 25,000
=    but it made no difference)
=
=2. If the values are stored as integers (8 bit bytes), then there only 256
=   possibilities, for the whole frequency range in any case.

Get a Sparc 10 with a 16 bits chip.

=
=Anyway, if anyone has an explanation, solution, or some alternative software
=that will perform better please let me know.
=
=
=Cheers - Adam.
