He does it again! Audio and video conversion is definitely Algo territory.
I know I keep repeating myself and it's getting old, but if he takes all his previous proof-of-concept audio and video stuff (picture conversion, bad apple converter, audio converters etc.), beefs it up, throws in some cool gfx fx too, then you will have a kick-ass demo on your hands. I'll shut up now. lol |

| @fatfrost. I assume you mean the Frodigi method? Yes, A wave sample from a sid can be recreated back to sid waveforms and frequencies. Obviously not perfect as the ADSR, Pulse Width, Sustain, Filter is not used in Frodigi1/2 at all hence a rather 'crude' conversion back to sid |

| Now can you make an example with a Sid that has been ogg filed then converted back?? ;) |

| @TLR. Absolutely. Its very much like fixed length lossy LZ78. However the major increase in quality is due to the amplitude adjustments where each sliding offset has its unique one of sixteen amplitude values to get more definition out of the small 4k data. |

Very impressive!
So basically you create a 4k dictionary of waveforms and map the original stream the closest way possible to it?
I assume you iterate that to find the closest to optimal solution.
Kind of like lossy LZ78 in a way. |

I am still experimenting in more optimum methods of creating the wavetable.
In this implementation I time shrunk the audio with interpolation so that there would be less dramatic transition jumps. It works rather well, but suboptimal. I have ideas on improving this method however. This way I can probably increase the compression rate without affecting the quality too much (in comparison to only using larger chunks) with the same wavetable method |

| Awesome! Any hints on how you created the 4k wavetable? |

\O/ Algorithm = Cycleburner in 2014^^
Awsome and can't wait to see where this is going! |
