Detailed Description
Conversions to and from various music and signal processing units. Note that: silence::Event represents loudness in MIDI units (0 to 127). silence::Orchestra represents loudness in gain (0 to 1). silence::WaveSoundfileOut represents loudness in amplitude (0 to 1 for float samples, 0 to 32767 for short samples). Loudness can also be represented in positive decibels (0 to 84 for short samples, 0 to whatever for float samples). For float samples, decibels are assumed to be equivalent to MIDI velocity; otherwise, MIDI velocity is rescaled according to the maximum dynamic range supported by the sample size. All loudness conversions are driven by sample word size, which must be set before use; the default is 4 (float samples).
