# VAG files
|
|
|
|
> VAG is the PlayStation single waveform data format for ADPCM-encoded data of sampled sounds, such as
|
|
piano sounds, explosions, and music. The typical extension in DOS is “.VAG”.
|
|
|
|
See [FileFormat47.pdf](http://psx.arthus.net/sdk/Psy-Q/DOCS/FileFormat47.pdf), p.209

## Audio to VAG conversion
|
|
|
|
We have to convert the audio file to RAW data first :
|
|
|
|
```bash
|
|
ffmpeg -i input.mp3 -f s16le -ac 1 -ar 44100 tmp.dat
|
|
```
|
|
|
|
then use [`wav2vag`](https://github.com/ColdSauce/psxsdk/blob/master/tools/wav2vag.c) to convert the data, making sure the `-freq=` parameter matches the `-ar` value used above :
|
|
|
|
```bash
|
|
wav2vag tmp.dat output.vag -sraw16 -freq=44100
|
|
```
|
|
|
|
## VAGedit
|
|
|
|
You can find a graphical editor in the [PsyQ sdk](http://psx.arthus.net/sdk/Psy-Q/PSYQ_SDK.zip) named `VAGEDIT.exe`.
