Hi folks
I have SB sound card and OSS driver
For read sound from line in i use such functions [see below]
How i can read signals from digital in ?
any example/idea welcomed
Tnx in advance

status = read(fdi, adat , sizeof( adat )); /* record some sound */
int fdi; /* sound
Terve
Try out this example
Split it in seperate files

Hello. I have problems in getting a shared memory to work.
What works is my shmalloc() which is used for sharing memory
over fork(). What does not work is sharing memory between
arbitrary processes. This latter uses

But for beginning i'm looking also for simple physical formulas
for gain calculation .
Is it RMS Gain (%) = sqrt ( sum 1..n ( sample[i]^2 ) ) / MAX_SINE_RMS
or Gain (%) = sum 1..n abs( sample[i] ) / MAX_SINE_AREA
Hi to developers
I'm search for realtime sound and peak gain indicator (db) algorithms and
formulas.
My first idea is all 16 bit absolute sound_sample_values in time interval
t1...t2 compare with ethalon sine wave
( where ethalon sine wave amplitude is 32000 and lenght/2 is t2-t1 )

Hi folks
I have two linux computers with ext3 and reiserfs file systems
=
follows mpg123 /my/lala.mp3 without -b option
If during da playing i make copy , scandir for big folders
and other intensive disk perations
Then sometimes sound breaks for o,x sec
Make tuning
I'm new to OSS Programming, and I'm attempting to play some 8bit wav files.
However OSS is telling me that my sound card will not play 8bit , only
16bit.
If I force it. The sound changes pitch, and is very fast. ( obviously ).
Is there anyway to convert 8bit to 16bit on the fly? I've
Hi folks
How i can from my linux C program at the same time
take sound from souncard line input ( ,maybe change level and something else )
AND give it back to line output
this program
do it but with pauses ~1sec
some ideas ?
Tnx in advance
