CD tools

There are miscelaneous tools for work with CD:

• CD-disassembler: Disassembler of CD subchannel data.
• gramofile2toc: Simple AWK convertor of gramofile tracks file (generated from wav source) to cdrdao toc file (tested on raw swabbed file).
• swab: Very simple swab filter (swaps byte order in raw audio file). CD-burning tools knows to do it on fly, but sometimes it is useful (for example for audio preview).
• p96toraw: Very simple convertor, which removes subchannel data from P96 RW_RAW file (cdrdao) to produce raw audio data.
• fromrawconvert and timeconvert: Two simple convertors between cdrdao toc formats - fromrawconvert: toc of raw96 -> standard toc, tomeconvert - time-oriented toc -> raw96 offset toc
• cdrdao-acd.patch: Patch for cdrdao for Almost-CD (so called “protected CD”. In case of L-EC use bad block data instead of sync sector. It sometimes causes data-mangling anyway (sector numbering can contain oddities).
• cdaudioscan: Simple CD audio sector tracker for MMC compliant devices. Starts playing audio from start, then 75 times per second monitors sector number. Helps to find sector numbering oddities on Almost-CD (so called “protected CD”).
