libcw/py/gen_wavetables

These scripts are used to generate notes from a MIDI sampler for a defined set of pitch and velocities. The notes and begin/end time markers are recorded where each recorded audio file contains all the velocities for a single pitch. The resulting samples are then used to calculate wavetables for use by the libcw wavetable oscillator. (see: dsp::multi_ch_wt_seq_osc and flow::piano_voice).

wt_util.py

Utilities used by all other modules

gen_midi_csv.py

Generate a MIDI file in CSV format to trigger the sampler with a sequence of velocities for a given pitch.

sample_ivory.py

Use the MIDI file from 'gen_midi_csv.py' to trigger the sampler and record the resulting audio and onset/offset TSV marker file.

calc_sample_atk_dur.py

Calculate a list [(vel,bsi,esi)] which indicates the attack wavetable.

calc_wavetables.py

Create a JSON file of wave tables for all pitches and velocities.

wt_osc.py

Generate a set of notes using the wavetables found by calc_wavetables.py. This program implements a wavetable oscillator which can interpret the wavetables created by calc_wavetables.py
