1 cdparanoia release III alpha 9 README
2 [March 19, 1998, updated March 27, 2001]
6 This CDDA reader distribution ('cdparanoia') reads audio from the
7 CDROM directly as data, with no analog step between, and writes the
8 data to a file or pipe as .wav, .aifc or as raw 16 bit linear PCM.
10 These are installation notes; for lots of other cdparanoia related

18 1. A CDDA capable CDROM drive (ATAPI, SCSI, or proprietary)
20 2. For proprietary drives:
21 2a. kernel support for the particular CDROM in use
23 For ATAPI CDROM drives:
24 2b. IDE cdrom (ATAPI) support
26 2c. IDE-SCSI host adaptor emulation
27 2d. SCSI cdrom support (optional)
28 2e. kernel support for the generic SCSI interface and proper device
29 (/dev/sg?) files in /dev. Most distributions already have the
30 /dev/sg? files. devfs [supported] sets this up automagically.
32 For SCSI CDROM drives:
33 2f. SCSI cdrom support (optional)
34 2g. kernel support for the generic SCSI interface and proper device
35 (/dev/sg?) files in /dev. Most distributions already have the
36 /dev/sg? files. devfs [supported] sets this up automagically.
38 3. A Linux 2.2.x, 2.3.x or 2.4.x kernel
40 ATAPI drives may be used either with the native IDE cdrom driver, or
41 with IDE-SCSI host adaptor emulation. Both work, but the SCSI
42 emulation mode works much better for CDDA extraction. Cdparanoia may
43 also be able to identify and use unusual drives that report 'CDDA
44 incapable' in native ATAPI mode.
46 /proc filesystem support is no longer needed, although you'll
47 certainly want to have it for other packages. Cdparanoia does not
48 require threading, IPC or sound card support.
50 Devfs is fully supported as of 9.8, with or without devfsd.
55 To build the cdparanoia utility:
60 This will compile cdparanoia and the shared paranoia libs; make
61 install (as root) will install it. Don't forget to run ldconfig;
62 unlike previous releases, this version uses shared paranoia libs; you
63 can still build the static version as follows:
68 Unlike cdda2wav and readcdda, cdparanoia is smart enough to find CDROM
69 drives and the appropriate interfaces automatically; if you have only
70 one CDROM drive, you'll not need to worry about it. If your machine
71 has more than one CDROM drive and cdparanoia finds the wrong one,
72 you'll need to tell it which device to use on the command line (see
73 the man page and Troubleshooting below).
75 To build the cdda_interface.a and cdda_paranoia.a libraries:
80 The .so shared libraries can be built as follows:
85 Other build notes (such as building and using a debugging version of
86 cdparanoia to aid me in tracking down any trouble) can be found on the
87 Cdparanoia web site at the URL given above.
89 Additional installation notes
90 =============================
92 Most Linux setups already have performed the steps described below,
93 and devfs also provides all the necessary device entries
94 automatically. The list is useful for doublechecking on a non-devfs
95 install. (originally taken from Heiko's cdda2wav README)
99 Cdparanoia requires the generic SCSI interface; you'll need
100 a kernel with compiled-in or module-supplied sg interface.
101 In case of a module, this has to be loaded ('modprobe sg';
102 usually done in boot time scripts).
103 This can be verified with 'cat /proc/devices'. It should
104 have a line under Character devices:
107 Cdparanoia also uses (but doesn't really require) the kernel SCSI
108 cdrom driver, ie, a kernel with compiled-in or module-supplied
109 cdrom support. In case of a module, this has to be loaded
110 ('modprobe sr_mod'; again, usually part of boot up scripts).
111 This can be verified with 'cat /proc/devices'. It should
112 have a line under Block devices:
115 If the modules are properly configured but not currently loaded,
116 cdparanoia will trigger loading during its autoscanning.
118 In the /dev directory there have to be these descriptors:
119 br-------- 1 cduser user 11, 0 Jan 23 1995 sr0
120 br-------- 1 cduser user 11, 1 Mar 24 1993 sr1
124 crw------- 1 cduser user 21, 0 Aug 27 1995 sga
125 crw------- 1 cduser user 21, 1 Aug 27 1995 sgb
126 crw------- 1 cduser user 21, 2 Aug 27 1995 sgc
129 and a link named 'cdrom' to the cdrom drive used. The link can be
130 to the cdrom device *or* the generic device. The link isn't required,
131 but it will speed autodetection.
133 Permissions and ownership can be changed at will, of course.
134 Here access is permitted only to user 'cduser'.
136 (for ATAPI and proprietary cdrom devices)
138 The kernel must have compiled-in or module-supplied cdrom support.
139 In case of a module, this has to be loaded ('modprobe <modulename>';
140 this is normally included in the boot-up scripts).
141 This can be verified with 'cat /proc/devices'. It should
142 have a line under Block devices:
143 <major> <name of cdrom driver>
145 In the /dev directory there have to be these descriptors:
146 br-------- 1 cduser user <major>, 0 Jan 23 1995 <cdrom device 1>
147 br-------- 1 cduser user <major>, 1 Mar 24 1993 <cdrom device 2>
150 a link named 'cdrom' to the cdrom drive used will speed up the
151 process of finding the cdrom (cdparanoia checks for the link first)
153 These steps are usually performed automatically during the
154 installation of Linux.
156 (for ATAPI cdrom drives using IDE-SCSI host adaptor emulation)
158 Overall, the instructions are the same as for normal SCSI drives.
159 To cause the CDROM drive to appear as a SCSI device instead of ATAPI,
160 the kernel must be compiled *with* SCSI and generic SCSI support, and
161 *without* IDE CDROM drive (ATAPI) support. If native ATAPI support is
162 enabled, the kernel will always choose to use the native ATAPI driver.
167 Specifically, 'cdparanoia' will not play to sound cards, do MD5
168 signatures, do rate reduction, or generally make use of the maximum
169 speed available from a CDROM drive. If your CDROM drive is *not*
170 prone to jitter and you don't have scratched discs to worry about,
171 look into Heiko's original cdda2wav.
