Hello all. Some updates available on <http://kokkinizita.linuxaudio.org/linuxaudio/downloads> Zita-resampler is a C++ library for sample rate conversion of audio signals. Full documentation is available in HTML format, see the 'docs' directory. Release 1.1.0 (26/01/2012) --------------------------- * VResampler class added - provides arbitrary and variable resampling ratio, see docs. * This release is NOT binary compatible with previous ones (0.x.x) and requires recompilation of applications using it. * This release is API compatible with the previous one. But if you are using the now deprecated filtlen() function please replace this by inpsize() which provides the same information. * The inpdist() function has been added, see docs. * The ratio_a() and ratio_b() calls have been removed, if this is a problem (I'd be surprised) they can be added again. * The include files are now in $PREFIX/include/zita-resampler/. Please DO remove any old ones manually after installing this version. Compiling using the old includes and linking with the new library will create havoc. * #defines and static functions are added for compile time and run time version checking, see resampler-table.h. Zita-alsa-pcmi is the successor of clalsadrv. It provides easy access to ALSA PCM devices, taking care of the many functions required to open, initialise and use a hw: device in mmap mode, and providing floating point audio data. Release 0.1.1 (26/01/2012) --------------------------- * This release is almost API compatible with clalsadrv-2.x.x. The only changes your source code will need are: - Change the include file. - Change the type of any objects defined by the library. - Replace calls to stat() by state(). - If you want error reporting on stderr, add an optional parameter to the constructor. See include file for details. * Added support for big-endian PCM formats. * Added support for reading and writing interleaved user buffers. * Error messages on stderr can be selectively enabled. If an app is compiled without them, they can be re-enabled at runtime by defining the environment variable ZITA_ALSA_PCMI_DEBUG, so they are now by default off. See source code for details. * Two simple demo programs are provided, one of them is the ALSA version of jack_delay. Complete documentation will follow later. The clalsadrv lib will remain available for some time, but any new releases of JAAA and JAPA will switch to the new one. Patches for AMS are being prepared. Both libraries have been updated mainly to provide the necessary functionality for two new apps: zita-a2j and zita-j2a. These allow to add ALSA hw: devices as a Jack client, same as the alsa-in and alsa-out clients that come with Jack. To see why I wanted something to replace those, have a look at <http://kokkinizita.linuxaudio.org/linuxaudio/resample.html> Both apps still need some cosmetics but they are in a working state. I'd want some more testing before they are released. If interested drop me a line off-list. Ciao, -- FA Vor uns liegt ein weites Tal, die Sonne scheint - ein Glitzerstrahl.
