- Cddarip is a new program that does the previously impossible. It allows
- one to extract audio samples directly from an audio CD (CDDA). Until the latest
- generation of drives (these expensive double speed drives), it was impossible to
- read audio samples through a CD-ROM player. Most units had provisions to play
- the discs when it is not being used for computer data, and would often furnish
- computer programs to emulate the buttons on a standard audio CD player. However,
- the units had their own DACs and audio was taken from a headphone or line output
- connected to the drive.
- This program is intended for the Toshiba XM-3401B drive. It MAY work on
- similar models by Toshiba, and it is rumored the Apple CD300 is a similar drive
- inside. CDDARIP has not been tested thereon. It will not likely work on other
- manufacturers units, thought the latest Sony and NEC drives could have this
- capability.
- This program came to being out of curiosity. I had obtained the Toshiba
- SCSI command manual to solve another problem(see fix_xa.lzh) and I discovered
- command capability to retrieve CDDA digital audio. I wrote a short program to
- grab an arbitrary sample and save it as a raw 8 bit file. I played back the
- result and low and behold, it sounded something like the original.
- To make it usable, an interface had to be generated, and this was 70% of
- the programming time. Plus everything is in BCD and some code had to be written
- to handle this. The result is basically a CDDA control program (CDDARIP can
- be used for this just fine). This allows the user to browse his CD to set the
- proper times to sample. Then he can actually sample the data to disk.
- Data from this can be used with other programs, as it puts it out in the
- standard IFF 8SVX format. Think of it, your favorite guitar licks can come up
- when there is a system message with 2.0 or above.
- Cddarip was compiled with SAS/C ® 6.02. It is designed to work with all
- 68000 family processors.

- REQIREMENTS:
-
- TOSHIBA XM-3401-B or similar 3400 series drive. Apple CD300 MAY work not tested.
-
- SCSI Interface that supports SCSI direct. Tested on Amiga 3000.
-
- Headphones or amplifier/speakers on 3401's audio output.
-
- WorkBench/Kickstart (TM Commodore-Amiga inc) 2.04 or greater.
-
- Note: It should NOT require any CD ROM filesystem as it accesses SCSI directly.
-
- Hard disk for saving larger samples.
-
- The music industry probably has concerns about perfect duplication of CD and
- other digital audio. This will not happen with CDDArip since the quality is
- degraded to 8 bits, less than a good analogue copy. Also the cost of media and
- drives for that magnitude of data would be many times the cost of the CD in a
- record store.
- This may be distributed by Fred Fish, and by any BBS, and any redistributable
- software library. And it may be distributed anywhere in the world.
