This section describes the mimium libraries.

Standard Libraries #

core.mmm #

• mix(gain,a,b)->float
• switch(gate,a,b)->float

Unit Conversions #

• midi_to_hz(note:float)->float
• hz_to_midi(hz:float)->float
• dbtolinear(db:float)->float
• linear2db(a:float)->float

math.mmm #

• PI
• log10(x:float)->float
• log2(x:float)->float

env.mmm #

• adsr(attack,decay,sustain,release,input)->float

filter.mmm #

• onepole(x,ratio)->float
• smooth(x)->float
• biquad(x,coeffs:(float,float,float,float,float))->float
• lowpass(x,fc,q)->float
• highpass(x,fc,q)->float

noise.mmm #

• gen_noise(seed)->float
• noise()->float
• unoise()->`float

noise() is same as gen_noise(1.0). Noise with the same seed returns always same number sequence.

The unoise macro is a mechanism for automatically allocating noise seeds. Each time you execute unoise!(), different seeded noise sources like gen_noise(1), gen_noise(2), etc. are embedded. However, all noise sources will always output the same deterministic uncorrelated noise each time.

If you need to use a noise source with a specific seed, use gen_noise directly.

osc.mmm #

• phasor(freq)->float
• phasor_shift(freq,phase_shift)->float
• saw(freq,phase_shift)->float
• triangle(freq,phase_shift)->float
• sinwave(freq,phase_shift)->float
