Release id #871 : Digi-Organizer V.1
How do i load samples into this? I know dirmaster must be involved but ive tried importing .raw files and .wav files (which ive compressed to 8-bit mono) and it dosent work |

Samples must be raw data, preconverted to 4bit IIRC. |

4-bit samples, indeed, with two samples per byte, and the first sample in the upper nibble. |

Well how do i convert into 4-bit? I know how to convert to .raw (export in mpt) but not 4bit? |

There doesn't seem to be any audio tool outputting fewer than 8 bits of raw mono PCM audio.
So you'll have to make do with those 8-bit .raw files and truncate the samples yourself with a small tool written in the language of your choice.
Take two bytes, then merge them with something like "((A & 15) * 16) + (B & 15)".
Note that this doesn't properly round the samples nor otherwise reduce the error. |

I had a similar problem, Durandal helped me to solve it:
Sample audio on C64, how to do a better conversion?
Here is the code:
