ArdVoice: A library to play audio (voices) on the Arduboy

By @igvina

Features:

Voice library:

Play compressed audio (works better with voices)
Good speed but can cause slowdowns on 60 fps games
Configurable speed (from 0.8 to 1.4)

Voice compressor (vocoder):

Works with wav (only 8000 Hz, mono, 1 byte PCM_UNSIGNED). I recommend Audacity to convert to this format
Configurable quality (from 0 to 10), default is 4
Good compression (from 88 bytes/s to 530 bytes/s)

Usage:

Vocoder (v0.2):

Syntax: java -jar vocoder0.2.jar audio.wav [-options]
- options:
  - -q VALUE Quality (0 - 10) default: 4
  - -gs SKETCH_FOLDER Generate sketch code
  - -v Play compressed voice
  - -anp PREFIX Array name prefix
  - -ver Show vocoder version
- examples:
```
  "java -jar vocoder.jar dog.wav -gs DOG -v -q 6"
  "java -jar vocoder.jar merry.wav -v"
```

Voice library (v0.1):

Install the ArdVoice library in the Arduino IDE.
Add in .ino file:
- #include <ArdVoice.h>
- ArdVoice ardvoice;
To play voice call function: ardvoice.playVoice (...).

Methods:

void playVoice(const char *audio);
void playVoice(const char *audio, uint16_t startTime, uint16_t endTime, float speed);
void stopVoice();
boolean isVoicePlaying();
