Lossless audio compression saves space compared to the original RCT2 WAV files. No audio data is lost; it is simply stored more efficiently.

The RCT2 audio is stored without much metadata. Data about original composers, performing artists, and the title of each piece of music can be added to the RCT2 music. For an implementation of these suggestions, check this project.

Compression methods

All three of these have very similar compression ratios.

  • The RCT2 soundtrack stored as FLAC is 58% of its original size, to 251 MB from 436 MB.
  • TAK works perfectly and can restore the WAVs to checksum-identical original files, but it's not natively cross-platform and it's not available under the GNU General Public License.
  • WavPack has near-identical compression results to TAK or FLAC, while remaining in WAV format. Neither FLAC nor WavPack can restore the WAVs to what they were like TAK can.

Names

All tracks have names: both "_____ style" and an even more official name (check the sound credits). We have heard from the composer for the RCT2 soundtrack that our track listing is correct. This listing is consistent with the MusicBrainz tagging style.

Other files

  • css1 is a special WAV for sound effects.
  • css2 contains the long "crowd" sound effect.
  • css10 and css16 are nearly empty, and are probably unused. The rest are seemingly just WAV files named as DATs. Check the header: RIFF %. WAVEfmt.
  • css35 is titled "MPEG-1 layer III audio" and though its bitrate is high (488 kbps as FLAC), it's possible that it was transcoded from MP3.
