AcoustID fingerprinter and webservice access for .NET framework 4.5 and .NET standard 2.0. See acoustid.org for information about the AcoustID project.

The original code for this project can be found at https://github.com/acoustid/chromaprint.

• AcoustID fingerprint calculation.
• AcoustID webservice access: Lookup or submit fingerprints using the LookupService and SubmitService classes in the AcoustID.Web namespace.

An example showing how to implement the IDecoder audio decoder interface using NAudio can be found in the wiki. A simple winforms example application is available here.

If you want to use the AcoustID webservice in your application, you need to get an API key from https://acoustid.org/. Once you have the key, register it with AcoustID.NET by setting

AcoustID.Configuration.ClientKey = "APIKEY";
