NA2FLAC Android

Standalone

NA2FLAC Android is the official Android port of NA2FLAC, written in Kotlin for ARM64 devices running Android 8.0 or newer. It scans a folder of Nintendo audio assets and converts them to FLAC using bundled vgmstream and FFmpeg. It handles the same formats as the desktop version (AST, BRSTM, BCSTM, BFSTM, BFWAV, BWAV, SWAV, STRM, LOPUS, IDSP, HPS, DSP, ADX, MP3, OGG), merges split _l/_r stereo files, and falls back to WAV for files above 8 channels. All dependencies (vgmstream, ffmpeg, ffprobe) are bundled in the APK, so no separate installs are needed. This is the mobile counterpart to the Windows NA2FLAC desktop app; use it when you need to convert assets directly on a phone or tablet rather than on a PC. Used for pulling audio out of Nintendo titles for lossless archival or DAW-ready output on a mobile device. As with the desktop build, the bundled FFmpeg is GPL-licensed while NA2FLAC Android itself is MIT.

wwiser

Wwise

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.

Doppler

Standalone

Doppler reads the local EVE Online game client, locates all Wwise sound banks (.bnk) and loose Wwise media (.wem) in the shared cache, and exports them to a folder of playable MP3 or WAV files. It covers embedded bank streams, loose WEM resources, every language voice bank, music, UI, ambience, ship, weapon, and turret audio. The tool downloads portable runtime dependencies (Node.js, vgmstream-cli, FFmpeg) into its own directory on first run, requires no admin access, and does not modify the game client. Output is resumable, grouped by source bank and authored client path, and accompanied by a JSON/CSV manifest and failure log. Exports are configurable via command-line flags for format (MP3/WAV), bitrate, worker count, output path, and more. A full 320 kbps MP3 export of the current EVE client produces roughly 9.5 GiB across ~20,000 files.

BnkExtractor

Wwise

BnkExtractor 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.
