You need to parse Wwise .bnk files to understand audio scripting structure or generate TXTP files that simulate Wwise playback in vgmstream.
about
wwiser is a parser for Wwise .bnk banks that reads and displays all bank chunks, including HIRC (audio scripting) data with properly identified fields. It cannot modify banks but provides comprehensive analysis of Wwise's internal structure.
The tool's primary use case is generating TXTP files that allow vgmstream to simulate Wwise's audio playback, including complex features like dynamic music stems and layered audio. It handles both Wwise's sound module (simple SFX) and music module (realtime-mixed stems), attempting to recreate the engine's behavior in a static playback format.
wwiser supports automatic name resolution from companion files like SoundbanksInfo.xml or custom name lists, and provides both a web-based viewer and command-line interface for exploring bank contents. It works with nearly all .bnk versions except the earliest two used in Shadowrun and Too Human.

BnkExtractor
WwiseBnkExtractor is a library for parsing and extracting content from Wwise soundbank files. It handles the proprietary .bnk container format used by Audiokinetic Wwise and extracts .wem audio files embedded within. The tool is designed for reverse engineering workflows, asset recovery, and technical analysis of Wwise-integrated games. It provides programmatic access to soundbank structures without requiring the original Wwise project files.
Fmod5Sharp
StandaloneFmod5Sharp is a managed C# library that decodes FMOD 5 sound bank files. It reads FSB5 files, extracts contained samples with their metadata (frequency, channels, names), and exports them to standard formats like WAV and OGG. The library supports multiple encoding formats including PCM variants, GCADPCM, IMAADPCM, Vorbis, and FADPCM. It handles both throwing and non-throwing load operations, provides format validation, and reports file extensions for supported codecs. The tool is primarily used for extracting game audio from Unity and Unreal Engine titles that use FMOD middleware. It exposes sample properties like frequency and channel count, making it useful for audio asset inspection and conversion pipelines. The library can rebuild audio data into standard file formats that can be played by common media players or further processed by other audio tools.
