## Sound

### Sound:

AppleWin emulates both the internal speaker and also the Mockingboard (or Phasor) sound card, using a PC sound card.

Use the AppleWin Configuration tab labelled Sound.

If you want to use a sound card then use at least DirectX 9.

#### Speaker:

You can now only emulate this with a sound card.

#### Mockingboard:

When the Mockingboards are enabled, the cards are physically plugged into slots 4 and 5 of the Apple II.

Each Mockingboard is a type 'C': 2x AY8910 (3-channel sound generator) & 1x SSI263 (speech chip)
Each AY8910 is fully emulated (tone, noise & envelope).
Each SY6522 (that controls an AY8910) can generate precise timer interrupts or phoneme-complete interrupts.
Emulation of the SSI263 is basic at the moment and only plays back phonemes at a fixed rate without any support for inflection or filters.
Additionally the Votrax/SC-01 (predecessor to the SSI263) is emulated by remapping Votrax phonemes to the SSI263's.

#### Phasor:

When Phasor is enabled, the card is physically plugged into slot 4 of the Apple II.

Phasor is equivalent to 2 Mockingboards: so has 4x AY8910 & 1x SSI263.
