HOW IT WORKS
Three steps, no account, nothing to install.
01
Upload your BNK file
Drag and drop a Wwise .bnk SoundBank from a game's audio folder, or select it from your device.
02
Extract the sounds
Keep WAV as the output format and start. Each complete sound stored in the bank is decoded to its own 16-bit WAV.
03
Download the WAVs
Download the sounds together as a ZIP, numbered name-1.wav, name-2.wav and so on. A bank with one sound gives a single WAV.
BNK
In games, BNK is most often the Audiokinetic Wwise SoundBank format. A bank stores a game's sound events and playback structure, and often embeds the sounds themselves as Wwise .wem audio. Some banks hold only events, or only short prefetch clips of sounds that the game streams from separate .wem files. Media players can't open .bnk files.
WAV
WAV is a RIFF-based audio format commonly used for uncompressed PCM audio. It is easy to edit and broadly supported in recording, broadcast, and desktop audio workflows.
FILE FORMATS
SOURCE
A BNK is an Audiokinetic Wwise SoundBank, the audio package of games built with Wwise. Banks hold events and playback rules, and often embed short sounds such as effects and voice lines as numbered entries, while longer sounds stream from separate .wem files. The embedded sounds have numbers, not names.
TARGET
Microsoft and IBM defined WAV in 1991. It normally stores plain PCM audio with no compression, which is why editors, DAWs, broadcast systems and speech tools accept it without question. The price is size: CD-quality stereo takes about 10 MB per minute, and tagging support is limited.
| Feature | BNK | WAV |
|---|---|---|
| Developed by | Audiokinetic (Wwise) | Microsoft and IBM |
| File extension | .bnk | .wav |
| Compression | Vorbis, ADPCM, PCM or Opus inside | None (PCM) |
| Size vs uncompressed WAV | Varies by codec | Same size (1:1) |
| Tags and cover art | Events, no sound names | Basic text tags, no cover art |
| Best for | Sound effects in Wwise games | Editing, mastering, speech tools |
| Plays on phones and browsers | No, needs vgmstream | Yes |
USE CASES
Practical workflows where BNK to WAV conversion is useful.
Get every sound from a bank at once
Turn a bank of footsteps, impacts or UI sounds into a set of WAVs instead of extracting them one by one.
Find a sound to replace in a mod
Listen through the numbered WAVs to find the effect or voice line you want to swap out.
Check a rebuilt bank before release
Mod authors can confirm that a repacked bank holds the right sounds, in the right order and at the right length.
Open Xbox 360 and PS3 banks
Big-endian SoundBanks from Xbox 360 and PS3 builds extract the same way as PC banks.
Handle banks that mix codecs
A bank that combines PCM, Vorbis and Opus sounds still gives one WAV per sound, each at its own sample rate and channel count.
Load bank sounds into a sampler
Bring a whole set of weapon, creature or interface sounds into a DAW or sampler as standard WAV files.
Compare sounds between game patches
Extract the same bank from two game versions and compare the WAVs to see which sounds changed.
Listen to a localized dialogue bank
Extract voice lines from a language-specific bank, such as an English or Japanese one, to compare the deliveries.
Study a game's sound design
Hear each layer of a game's effects on its own to learn how its sound team built the mix.
Archive a game's embedded sounds
Keep the sounds of a bank as standard WAV files that audio software will open for years to come.

TROUBLESHOOTING
Game audio works differently from normal music files, which explains most surprises.
01
The file held several sounds, so each one became its own WAV, numbered in bank order. Sounds have numbers, not names.
02
Banks such as Init.bnk hold only events or keep sounds in separate .wem files. Convert those .wem files instead.
03
Prefetch clips, the first moments of sounds streamed from .wem files, are skipped so only complete sounds are delivered.
04
Skipped entries close up the numbering, so download 5 isn't always the bank's fifth entry.
05
Looping game music is rendered the way the game plays it: the looped section plays once more, then fades out over 10 seconds. A loop covering the whole track plays once.
06
The file is damaged, isn't really BNK audio, or was extracted with the wrong tool. Extract it again from the game files and retry.
vgmstream is the reference decoder for game audio, used through foobar2000 or the command line. dragdropdo runs the same decoder in the browser, so you can turn BNK into WAV on any device.
| What matters | dragdropdo | vgmstream and Desktop Tools |
|---|---|---|
| Nothing to install | ✓Yes. Runs in any modern browser. | ~foobar2000 plus the vgmstream plugin, or vgmstream-cli. |
| Works on phones and tablets | ✓Yes. Desktop, Android, iPhone and iPad. | ~No. Windows and command-line tools. |
| Batch conversion | ✓Yes. Add many files and download one ZIP. | ~Yes, with scripts or foobar2000's converter. |
| Share finished files | ✓Yes. Send a unique link from the result page. | ~You upload and share the files yourself. |
| Pricing | ✓Free with daily limits. $2.99 or $6.99 passes for unlimited use, no monthly plan. | ~Free. |
| Choosing loop count and fade | ✓Fixed: an inner loop plays twice, then fades over 10 seconds. | ~Yes. vgmstream-cli sets the loop count and fade length. |
Other tools use different pricing, limits and workflows. This comparison describes dragdropdo's own features without assuming every other tool works the same way.
