output: 'out.wav',
gate: true,
compress: true,
pan: -0.25,
treble: -0.1,
bass: 0.8,
extrastereo: false,
volume: 1.2,
trim: 0.1,
reverb: 0.2
})
input
- the path, URL or Node.js ReadStream of the input audiooutput
- the path, or Node.js WriteStream of the output audioe.g
await channelstrip.mixdown({
input: 'https://mydomain.com/test.wav',
output: 'out.wav',
gate: true,
reverb: 0.25
})
Many file formats are supported, with the file extension indicating the file type:
