Odyssey - Classic Audio

Description

Odyssey - Classic Audio is an audio restoration mod for Halo: Campaign Evolved, created to bring the game’s soundscape closer to the identity of the original Halo trilogy.

Halo: Campaign Evolved presents the OG campaign through a hybrid modern engine and audio system powered by Audiokinetic Wwise, but many of the sounds differ considerably from their classic counterparts. This project aims to restore and carefully re-adapt weapon audio, vehicles, ambience, effects and other audio elements. And, the part that might surprise you, none of the actual original game assets are used.

Documentation from the Odyssey Sound Team over the past many years has revealed a large swathe of the game's audio is pulled from various 'stock' sound libraries. (Late Night Gaming made a video on this exact topic, check it out!  With this information, and said libraries, it is possible to recreate the original game audio nearly 1:1, with the added benefits of the source audio being uncompressed (and often stereo). This means far higher quality audio, properly fitting Campaign Evolved, while still, more or less, being the exact same, recognizable iconic sounds you heard back in 2001. All of what you will hear is (or will be) featured in other Halo fan projects, such as Ringworld Alpha or Halo 2: Classic Remastered.

Alongside this, some audio from Halo 2 and Halo 3 has been brought back - plans are to replace the Plasma Rifle's audio, and the Hunter's Assault Cannon audio with their Halo 2/3 counter parts, plus whatever else I can think of down the line.

What's currently in?

Good question. Right now, the firing audio for the Assault Rifle, Battle Rifle, Chaingun, Shotgun (incl. some foley audio), Plasma Pistol and Sniper Rifle have been replaced. Additionally, the klaxon alarm heard on the Pillar of Autumn has been replaced, the Banshee's engine sound is replaced (but needs some more work), the UI audio is mostly replaced, and the 'tron' music cue has been replaced with a cover of the Menagerie from Halo 3: ODST which was done by me during initial testing while trying to get music swaps in working order. I've left it for now, since the places 'tron' is heard throughout the game is pretty jarring, and this is a slightly better fit, all things considered.

At some point, I'll be replacing it with another track, if not disabling it and other new music cues entirely.

Oh yeah, the Warthog engine audio is back to its' original Halo Trilogy sounds.

Right now, the tooling necessary to pull off these kind of swaps are still in their infancy or undeveloped, meaning that once better tooling is developed for working with the existing Wwise implementation Campaign Evolved uses, progress will steadily pick up steam.
