Jack capture

jack_capture

==

jack_capture is a program for recording soundfiles with jack. It's default operation is to capture whatever sound is going out to your speakers into a file, but it can do a number of other operations as well.

Note that the above link doesn't seem to currently work because of something which seems to be www upgrade at Notam. But this link does seem to work for now:

0.9.10 -> 0.9.17:

*Do not accept filename starting with "-" when filename is last argument.
*Added the "--filename"/"-fn" option to set filename not
 as the last argument. Can also contain "-" as first character.
*Fixed colors a bit and removed a superfluous linebreak.
*Fixed segfault for missing values in commandline.
*Manually clear allocated memory instead of using calloc.
*Removed buffer-info line when recording to stdout.
*Removed printing of "continue recording" when writing the last overruns.
*Niceify the disk writing thread to -20 when more than half the buffer is used.
*Continously show buffer usage, total number of overruns and whether
 the disk thread has high priority, in the console. Turn off by using
 the -hdu option.
*Added option -dc to disable console update. (same as "-dm -hdu")
*Fancier colors.
*Removed "hepp".
*Made dB meter the default and replaced the -dB option with the -lm option.
*Made the console meter wider to fit the info line at the bottom.

Snd-ls

==

Snd-ls is a distribution of Bill Schottstaedt's sound editor SND. (http://ccrma.stanford.edu/software/snd/)

Its target is people that don't know scheme very well, and don't want to spend too much time configuring Snd. It can also serve as a quick introduction to Snd and how it can be set up.

Snd-ls also serves as base code for the San-Dysth softsynth (http://www.notam02.no/~kjetism/sandysth/) and the Snd-rt music programming language (http://www.notam02.no/arkiv/doc/snd-rt)

Changes 0.9.8.16 -> 0.9.8.17:

*(read-enable 'positions) has been wrongfully
 turned off for some time. Bactrace should work
 again now. (This only affects people using
 snd-ls for programming.)

Rollendurchmesserzeitsammler

================

The Audio Rollendurchmesserzeitsammler is a conservative garbage collector providing general ways to efficiently allocate and use memory inside a realtime audio thread without having to manually free it later.

Changes 0.0.1 -> 0.0.4

• Added support for iterior pointers. (Pointers which points inside

 middle of allocated memory). Turned out Stalin depended on this,
 plus that c compiler are free to store pointers in registers
 and stack however they want, so it's better to be safe.

• Fixed header.
• Made it packagable. Write make and make install to install library file

 and header files.

• Added the function tar_get_dynamic_roots_for(char *pointer,char **start,char **end).

 This function requires the source for HBGC:

• Note that there are ways to increase the execution speed

 significantly, I just haven't had the time yet, so this update doesn't
 contain all the changes I wished for.

---

*Made sure the process thread won't continue sending
data when jack_capture is told to quit. This
led to a race conditions when recording too many channels
at once (which was 256 channels on my machine).
*Added the jack_capture_gui script, based on code
by Svend-Erik Kjær Madsen's.
*Replaced sh by bash to make it work in ubuntu.
*Fixed exact port name match and gen_setformat. Thanks to
Gabriel J.L. Beckers for reporting the bugs.
*Increased the time the console meter is displayed in red from
50ms to 2000ms. (when the recorded jack value is equal to or
higher than 1.0.)
*Added the -dBr argument to specify reference level when using
the console dB meter.
*Added the -mr argument to specify reference level when using
the meterbridge meter.
*Added peak indicators to the console meter. Code to do so taken
from meterbridge by Steve Harris.
*Updated --help and README with the new options.
*Added option "-mt" to change meterbridge type. Current valid
options are vu (default), ppm, dpm, jf or sco. It's not necesarry
to specify "-mb" if using "-mt".
*Added option "-dB" to get a dB meter for the console meter.
*Added examples how to record ogg and mp3 files using the -ws option.
*Decreased default buffersize from 60 to 20 seconds.
(I even had trouble provocing underruns using a minimal
 0.05 seconds long buffer, so 60 seconds was obviously overkill)
*Fixed message and error printing to stderr when
vu meter is running.
