Early Audio

This is a sub-page of Proto:Sonic Adventure 2 (Dreamcast)/The Trial.

Every track was altered in later builds, as none of the audio used in this version matches the final's audio, most notably City Escape/City Escape 3.

As only one stage is available in this demo, only eight tracks are present.

Audio Differences#

Music

All of the tracks used in this build have either have minimal or quite significant differences compared to what's heard in the final. This (and similar to but unlike the Preview) version uses 44100 Hz for all tracks, but they use 32000 Hz in the final game to save space, while the "Coming 2001" file would be deleted after this build (with more info on that below).

Title Screen#

The ending of the title screen music is different and the lead guitar is quieter.

Let's Make It#

The intro from the final is notably missing here. However, there were also additional drum sounds at the beginning of this build's track that would be removed in the final version.

City Escape#

City Escape's track starts off differently and does not include vocals yet. This build uses different instruments than the earlier demo track. It should be noted that the instrumental at 0:24 - 0:38 would later be used and remixed in Sonic Generations as the guitar solo for Classic Sonic's City Escape stage.

City Escape 2#

The track was rearranged slightly at 0:36 for the final release.

City Escape 3#

Similar and/or same as the first track above, but without the opening, and instead used for when the player restarts from the last checkpoint after losing a life and when the speed shoes or invincibility wear off after a few seconds.

Invincible#

The drums at 0:07 are reused from the beginning of the track. The final trims 0:07 slightly while some additional drum sounds would be added at 0:08.

Speed Up#

The instruments in this demo sound much closer to Sonic Adventure. This would have a more unique remix in the final version.

Round Clear#

While nearly identical to the final, the ending lasts ever-so-slightly longer than the final version.

Sound

Sonic's Voice#

See this section for the early cutscene.

Checkpoint#

This page or section needs more audio. There's a whole lotta words here, but not enough audio. Please fix this. Specifically: Rip the sound.

The checkpoint sound is similar to Sonic Adventure.

Other Differences#

• After clearing City Escape, the "COMING 2001" screen is shown, with a voice clip accompanying it that's not present in the final version nor any later builds, as the coming.adx file was deleted within the next build of the game and completely removed from the final.

• The whistle that Sonic makes, as well as the sound that an animal makes when you get it, are erroneously played at a lower sample rate and are significantly shorter in length and higher in pitch as a result.
• There is a small click noise when Sonic gets on a rail that is not there on the final.
• When the player's rank is shown at the end of the stage, it makes the emblem jingle noise as opposed to the metallic thud sound in the final.
