 Re: Creating new Speech Data for the V364

@Gaia: I play the ABeeC-demo on both emulators again:
Correction:
* You can here something in Yape, but is more noise then speech. (I had in mind, that you hear nothing)
* In Vice you can here actually voice, very high and fast, but it plays voice.

The unusual here is, that the SpeechData-format has the 48 bit/frame format, but with no compression (Bit 6 is set to 0) (Config-Byte: 03).

The Config-byte
low Nibble:
Bit Function Set 0 Set 1
0 Filter stages 10 8
1 Repeat available not available
2 Frame length 20 ms/frame 10 ms/frame
3 Bits/Frame 48 bits/frame 96 bits/frame

high Nibble
4 Loss effect calculation none available
5 Sound source shape Pitch Triangle
6 Speech Data Uncompressed Compressed
7 ? not used, same as Bit 6
