# HOWTO To Create Training Set of GOAT Warren Buffett for Mozilla TTS

Following https://stackoverflow.com/a/66307612

Use the `LiveRecorder` Firefox plugin to record from Youtube.

Convert from webm to audio-only ogg.
```
ffmpeg -i berkshire-1994.webm -vn -acodec copy ./berkshire-1994-00:00_10:00.ogg
```

Split by silence. This automated splitting of files is the killer app for command-line audio tools, imo.

```
sox ./berkshire-1994-00:00_10:00.ogg berkshire-1994-00:00_10:00-.wav silence 1 0.2 0.5% 1 0.2 0.5% : newfile : restart
```

Play with trimming (start and duration)
then when you narrow down the clip, you can use `sox` to trim.
This is where GUIs like Audacity are still better.

```
play ./berkshire-1994-00:00_10:00-149.wav trim 0:00 0:02.5
sox ./berkshire-1994-00:00_10:00-149.wav ./berkshire-1994-00:00_10:00-149a.wav trim 0:00 0:02.5

```
