| Summary : Sound Blaster 16 ASP/CSP control program
|
Description :
Cspctl is a Sound Blaster 16 ASP/CSP control program. It is a simple CSP
microcode loader for Crative Sound Blaster 16ASP and some Sound Blaster AWE32
sound cards with Creative Signal Processor (CSP) chip (CT1748A) installed.
cspctl can also be used as a post-install function to snd-sb16-csp module to
load default codec at module installation.
If CSP chip is successfully detected and initialized, it will be installed as a
hardware dependent device hwC0D2 into /dev/snd directory. Currently, following
codecs can be loaded to CSP device:
- wfm0001a.csp QSound decoder
- wfm0006a.csp A-law codec
- wfm0007a.csp u-law codec
- wfm0011a.csp IMA ADPCM codec (distorted output for IMA test files)
- wfm0200a.csp Creative ADPCM codec (maybe Intel/DVI IMA ADPCM compatible)
- wfm0202a.csp Fast Speech 8 codec
- wfm0203a.csp Fast Speech 10 codec
These codecs are not yet supported by ALSA:
- wfm0201a.csp Text2Speech decoder
With QSound decoder microcode loaded, all simple PCM file formats can be
played with QSound 180 degree positioning applied. QSound element is
dynamically added into mixer structure as 3DEffect1-space element. It will
only show if support for CSP has been compiled into ALSA drivers, CSP chip
has been found, and QSound codec is loaded into CSP. When enabled, QSound
position can be dynamically changed by mixer slider.
Driver supports autoloading of u-Law, A-Law and Ima-ADPCM hardware codecs.
Autoloading is active only when there is no microcode loaded to CSP, and there
is no need to preload appropriate *.csp files.
If hardware codec microcode has been manually loaded, then CSP will support
only loaded PCM format and autoloading will be disabled. In such case, proc
interface will show loaded codec properties:
