It just wrote first 100000 samples to the file "rawout" in plain text format.
I have simple program which helps me to analyse such files.
With that program I've found that some samples are lost (~ one per 4000)
(My settings: latency_min = 8192; /* in frames / 2 */
latency_max = 8192; /* in frames / 2 */
block = 1; /* block mode */ // When set to 0 I got awfull sample lost
tick_time = 1; /* disabled, otherwise in us */
tick_time_ok = 0;
use_poll = 1;
)
What can I do to not loss that samples in full duplex mode?
Sorry for my English. Eugeni.
latency.c:
/*around string N649*/
ok = 1; // was here
in_max = 0; // was here
//prepare big buffer
double* filebuf = malloc(500000*sizeof(double)); //I've added
int filebufp = 0; //I've added
FILE* file; //I've added
short* shortbuf; //I've added
int i; //I've added
while (ok && frames_in < loop_limit) { // was here
if (use_poll) { // was here
/* use poll to wait for next event */ // was here
snd_pcm_wait(chandle, 1000); // was here
} // was here
if ((r = readbuf(chandle, buffer, latency, &frames_in, &in_max)) < 0) // was here
ok = 0; // was here
else { // was here
if (effect) //I've added // was here
applyeffect(buffer,r); // was here
shortbuf = (short*)buffer; //I've added
//write to big buffer
for(i=0; i<r; i++) //I've added
{ //I've added
filebuf[filebufp] = shortbuf[i]; //I've added
filebufp++; //I've added
} //I've added
//write big buffer to file
if(filebufp>100000) //I've added
{ //I've added
file = fopen("rawout", "w"); //I've added
for(i=0; i<100000; i++) //I've added
fprintf(file, "%f\n", filebuf[i]/32000); //I've added
fclose(file); //I've added
exit(1); //I've added
}
