Synthesis

muspy.write_audio(path, music, audio_format=None, soundfont_path=None, rate=44100, gain=None)

Write a Music object to an audio file.

Supported formats include WAV, AIFF, FLAC and OGA.

Parameters

• path (str or Path) – Path to write the audio file.

• music (muspy.Music) – Music object to write.

• audio_format (str, {'wav', 'aiff', 'flac', 'oga'}, optional) – File format to write. Defaults to infer from the extension.

• soundfont_path (str or Path, optional) – Path to the soundfount file. Defaults to the path to the downloaded MuseScore General soundfont.

• rate (int, default: 44100) – Sample rate (in samples per sec).

• gain (float, optional) – Master gain (-g option) for Fluidsynth. Defaults to 1/n, where n is the number of tracks. This can be used to prevent distortions caused by clipping.

muspy.synthesize(music, soundfont_path=None, rate=44100, gain=None)

Parameters

• music (muspy.Music) – Music object to write.

• soundfont_path (str or Path, optional) – Path to the soundfount file. Defaults to the path to the downloaded MuseScore General soundfont.

• rate (int, default: 44100) – Sample rate (in samples per sec).

• gain (float, optional) – Master gain (-g option) for Fluidsynth. Defaults to 1/n, where n is the number of tracks. This can be used to prevent distortions caused by clipping.

Returns
