Subject: [ecasound] ecasound on dell laptop working

Just wanted to let Kai (and the gang) know that this newbie has got
ecasound working with the Dell Inspiron laptop with Linux 7.2 --
maestro driver, OSS/Free as shipped w/Linux (in other words a very
turnkey out-of-the-box system with no kernel hacking involved).

discovered a good mixer (mix-2000) along the way -- but if anyone
would like to recommend a better one I am listening :-)

wavrec still does not work, but ecasound does a great job of recording,
so I am not going to waste a lot of time figuring out why wavrec
doesn't work.

question; when recording with

        ecasound -i:/dev/dsp -o somefile.wav

is there any way to stop the recording other than ctrl-c? so far I
have only read the Example Commands, so as to get started right away
and find out how well audio capture works w/my hardware. I confess
I have not yet properly read the manuals :-)

if other folks on this list could comment on what other tools they
use with ecasound I would be very interested to hear about wav file
editors, standalone noise filters etc. I built Gmurf but as yet I
don't understand what it does.

my adventures so far are very small beginner steps:

        ecasound -i:/dev/dsp -o somefile.wav
        ecasound -i somefile.wav -o /dev/dsp
        lame somefile.wav somefile.mp3
        mpg123 somefile.mp3

I can hear a loss of quality in the mp3 output, but the compression
is about 10 to 1 and the quality loss is not nearly that large :-)
so I am impressed.

could more experienced ecasound (and linux digital audio) hackers
please recommend any good books and/or FAQs which would bring me
quickly out of the analog realm and into this new world? topics
I am particularly interested in are quality enhancement, i.e. how
to make the final mp3 sound good -- how to burn my own audio CD
using linux -- how to use portable mp3 players -- how to make new
multitrack recordings using ecasound -- how to mix down multi-wav
multitracks to stereo master -- MIDI to wav and incorporating MIDI
tracks into multitrack recordings -- what horsepower (MHz rating)
CPU is recommended -- and if I decide to use a "real" machine
instead of a laptop, what sound cards are the most reliable and
best value for the $$.

I realize this is an overwhelming list of newbie questions which
is why I am asking for FAQs and book recommendations rather than
for answers :-) Just send URLs and I will go and read...
I'll also be using google to try to find some documents that answer
these qs.

best wishes (and THANKS Kai and the team for ecasound!)
