This Soundcard does not +need to be synchronized with the jackd Clocksource. + +alsa_in/alsa_out tries to resample the output stream, to reduce clicks. + +.SH OPTIONS +.TP +\fB\-j \fI jack_client_name\fR +.br +Set Client Name. +.TP +\fB\-d \fI alsa_device\fR +.br +Use this Soundcard. +.TP +\fB\-c \fI channels\fR +.br +Set Number of channels. +.TP +\fB\-r \fI sample_rate\fR +.br +Set sample_rate. The program resamples as necessary. +So you can connect a 44k1 jackd to a soundcard only supporting +48k. +.TP +\fB\-m \fI max_diff\fR +.br +The value when a soft xrun occurs. Basically the window, in which +the dma pointer may jitter. If you see "delay=" in the output of alsa_out +this is too small. +.br +Make sure target_delay is bigger than this. +.TP +\fB\-t \fI target_delay\fR +.br +The delay alsa_io should try to approach. Tune this to get lower latency. +Must be bigger than max_diff for alsa_out, and should be bigger than max_diff+jackd_period +for alsa_in. +.TP +\fB\-f \fI catch_factor\fR +.br +This value sets how fast the samplerate will change. +default is 1000. Try 10000 when you have good relation between +your clocksources. This will make resampling inaudible for example. +.TP +\fB\-p \fI period_size\fR +.br +Set the period size. It is not related to the jackd period_size. +Sometimes it affects the quality of the delay measurements. +Thats why its configurable. +.TP +\fB\-n \fI num_period\fR +.br +Set number of periods. See note for period_size. + +.SH AUTHOR +Torben Hohn +.PP +This manpage was written by Torben Hohn <torbenh@gmx.de> + diff --git a/man/alsa_out.1 b/man/alsa_out.1 new file mode 100644 index 0000000..d9de8dd --- /dev/null +++ b/man/alsa_out.1 @@ -0,0 +1 @@ +.so alsa_in.1 |
