ffmpeg

Converting Audio into Different Formats / Sample Rates

Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma

You can get the list of supported formats with:
ffmpeg -formats

You can get the list of installed codecs with:

	const Web3 = require("web3");
	const BN = Web3.utils.BN;

	(async () => {
	const network = "mainnet";
	const web3 = new Web3(

	Read a PFM file into a Numpy array. Note that it will have
