| ; DAC Frequency Algorithms | |
| ; ------------------------ | |
| ; Multiple algorithms can be defined. | |
| ; Each algorithm has its own section [$0] .. [$F]. | |
| ; The default section at the beginning of the file is [$0]. | |
| [$0] | |
| ; There are 2 ways of doing the default algorithm. | |
| ; 1. Frequency = BaseRate / (RateDiv + Rate) | |
| ; 2. Simulate a Z80 running at 3579545 Hz where the DAC loop takes | |
| ; BaseCycles + LoopCycles * (Rate-1) cycles. | |
| ; Within one loop, LoopSamples samples (not bytes!) are generated and played. | |
| ; Way 2 is preferred, way 1 is used when there is no BaseCycles value. | |
| BaseRate = 275350 | |
| RateDiv = 12.12 | |
| BaseCycles = 341 | |
| LoopCycles = 26 | |
| LoopSamples = 2 | |
| RateMode = 0x00 | |
| ; Sets, which compression types should use this algorithm by default. | |
| ; Possible values: All, PCM, DPCM | |
| DefCompr = DPCM | |
| [$1] | |
| BaseRate = 11025 | |
| RateDiv = 0.00 ; RateMode 0 only | |
| ; RateMode chooses the actual algorithm used for calculating the freuqency. | |
| ; 0 - base speed decreased by Rate | |
| ; 1 - Rate is a fraction of RateOverflow, multiplied by BaseRate | |
| ; So a low Rate value means a low frequency. | |
| ; Note: Rate > RateOverflow results in a speed higher than BaseRate. | |
| ; 2 - like 1, but Rate is the inverse fraction | |
| ; That means, that Rate = 0 is the base speed, Rate = RateOverflow is frequency 0. | |
| RateMode = 0x01 | |
| ; 100% fraction value for Rate (default is 0x100) | |
| ; Note: RateDiv and RateOverflow override each other. | |
| RateOverflow = 0x100 | |
| DefCompr = PCM | |
| ; Global Settings (algorithm-independent) | |
| ; --------------- | |
| ; Resample Mode: | |
| ; 0 - normal | |
| ; 1 - linear interpolation | |
| ResampleMode = 0x01 | |
| ; first Drum ID value (hexadecimal value, default is 81) | |
| DrumIDBase = C8 | |
| ; The [Banks] section can be used to remap (BankID, SoundID) to the final DAC Sound ID. | |
| ; The SMPS songs can switch between these banks to change what DAC sound appears to be the "first" one for them. | |

| ; Compression - can be PCM or DPCM | |
| Compr = PCM | |
| ; File Name - file path relative to the directory of this .ini | |
| File = DAC_81.bin | |
| ; Playback Rate - determines playback speed using the formula above | |
| Rate = 0x100 | |
| ; YM2612 Panning flags | |
| ; possible values: | |
| ; 0x00 (default, don't change panning) | |
| ; 0x40 (force left) | |
| ; 0x80 (force right) | |
| ; 0xC0 (force center) | |
| Pan = 0xC0 | |
| ; restart the sound after it finishes - can be False (default) or True | |
| Looping = False | |
| ; play the sound backwards - can be False (default) or True | |
