BCWAV
BCWAV is the Nintendo 3DS format for short sounds: sound effects, voice clips, jingles and the sounds of HOME Menu themes. Like BCSTM it uses DSP-ADPCM or PCM and can hold loop points, but it is loaded into memory instead of streamed.

HOW IT WORKS
Convert BCWAV to WAV in three steps
Three steps, no account, nothing to install.
01
Upload your BCWAV file
Drag and drop a stand-alone .bcwav sound, for example one extracted from a .bcsar sound archive, or select it from your device.
02
Convert to WAV
Keep WAV as the output format and start. PCM16, DSP-ADPCM and IMA-ADPCM audio is decoded to 16-bit PCM.
03
Download the WAV
Download one WAV per BCWAV file. It opens in Audacity, any DAW and common media players.
BCWAV
BCWAV (CTR wave) is the Nintendo 3DS format for short sounds such as sound effects, voices and menu sounds, and it is also used in custom 3DS themes. It holds PCM, DSP-ADPCM or IMA-ADPCM audio, often with a loop point. In games, these sounds are usually packed inside .bcsar sound archives.
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
BCWAV and WAV compared
TARGET
WAV
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 | BCWAV | WAV |
|---|---|---|
| Developed by | Nintendo | Microsoft and IBM |
| File extension | .bcwav | .wav |
| Compression | DSP-ADPCM or PCM | None (PCM) |
| Size vs uncompressed WAV | About 1/4 (ADPCM) | Same size (1:1) |
| Tags and cover art | Loop points, no tags | Basic text tags, no cover art |
| Best for | 3DS effects and theme sounds | Editing, mastering, speech tools |
| Plays on phones and browsers | No, needs vgmstream | Yes |
USE CASES
Use Cases for BCWAV to WAV
Practical workflows where BCWAV to WAV conversion is useful.
Preview sounds for a 3DS theme
Theme makers can listen to a BCWAV in any player, or open it in an editor, before putting it into a custom theme.
Get 3DS menu and system sounds
Convert extracted 3DS home menu and system sounds into WAV files for a video, a soundboard or a fan project.
Edit sound effects for a 3DS mod
Modders open the original sound in Audacity as a WAV to match the length and volume of a replacement.
Collect character voice clips
Put character voices from a 3DS game into WAV files that any video editor or soundboard accepts.
Audition a .bcsar dump
A .bcsar archive can hold hundreds of sounds. Extract the BCWAVs, convert them in one job and preview each WAV in a file browser or DAW.
Check how a sound loops
Looped BCWAVs play the intro, the loop twice and a 10 second fade, so you can hear where the loop joins.
Sample handheld sounds for music
Producers can sample 3DS sound effects and jingles in WAV, which every sampler and DAW accepts.
Use 3DS sounds in a stream
Add a 3DS jingle or menu sound as a stream alert in OBS.
Archive 3DS game audio
Keep decoded copies of a game's sound effects that open on any computer, at the 3DS-native 32728 Hz rate where the game uses it.
Document sounds on a game wiki
Wiki editors can turn extracted BCWAVs into WAV files and then encode them for the web.

TROUBLESHOOTING
WAV Not Sounding Right?
Game audio works differently from normal music files, which explains most surprises.
01
The track repeats and fades out
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.
02
It says the BCWAV is incomplete
A file holding less than 97% of the audio its header describes was cut off while extracting or downloading. Upload the complete file.
03
It says the file can't be decoded
The file is damaged, isn't really BCWAV audio, or was extracted with the wrong tool. Extract it again from the game files and retry.
04
The WAV is very large
WAV is uncompressed, about 10 MB per minute for 44.1 kHz stereo and more for higher rates or extra channels.
05
The sound is very short
Most BCWAV files are short effects. That's the whole sound.
06
A music stream isn't accepted
3DS music uses BCSTM. Use our BCSTM to WAV converter.
COMPARISON
dragdropdo vs. vgmstream and Desktop Tools
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 BCWAV 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.
