EchoPrintSharp .NET Standard Library

Library that generates an EchoPrint audio fingerprint string from PCM audio data.

How To Use

Add the Nuget package to your project

Install-Package EchoPrintSharp.Netstandard -Version 1.1.1

or the old PCL:

Install-Package EchoPrintSharp

then add some code:

using EchoPrintSharp;
...
var pcmData = new Int16[441000]; // 40 seconds x 11,025Hz = 441,000 samples, for example
... // put your mono/11,025Hz audio data in pcmData here
var echoPrint = new CodeGen();
string epCodes = echoPrint.Generate(pcmData);

If your audio data is not in mono/11,025Hz/16bit format, use this call:

...
string epCodes = Generate(pcmData, bitsPerSample, numberOfChannels, samplingrate)
