## filter_test
|
|
This is a basic utility for testing the Ploopy headphones filtering routines on a PC.
|
|
|
|
### Usage
|
|
Find a source file and use ffmpeg to convert it to PCM data:
|
|
|
|
```
|
|
ffmpeg -i <input file< -map 0:6 -vn -f s16le -acodec pcm_s16le input.pcm
|
|
```
|
|
|
|
Run `filter_test` to process the PCM data. The `filter_test` program takes two arguments an input file and an output file:
|
|
|
|
```
|
|
./filter_test input.pcm output.pcm
|
|
```
|
|
|
|
You can listen to the output audio using ffplay (which is usually included with ffmpeg:
|
|
|
|
```
|
|
./ffplay -f s16le -ar 48000 -ac 2 output.pcm
|
|
```
|
|
|
|
If there are no obvious problems, go ahead and flash your firmware. |
