# pcmdiff(1)

proof-of-concept raw PCM deltifier

## Name

pcmdiff — proof-of-concept raw PCM deltifier

## Syntax

**pcmdiff** *file1* *file2* **\>***file3*

## Description

pcmdiff will compute the arithmetic difference between the raw PCM files *file1* and *file2* and write it to stdout. This allows one to make the degradation that inherently comes with lossy audio formats, audible.

## Examples

```
	oggenc -q0 -o test.ogg test.wav;
	oggdec -o test2.wav test.ogg;
	pcmdiff test.wav test2.wav >delta.wav;
```
