You need to batch-convert Nintendo audio formats (BRSTM, BCSTM, BFSTM, AST, LOPUS, IDSP, etc.) to FLAC on an Android device while preserving folder structure.
about
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.
