FileSignatures VS NAudio

There seem to be a few in nuget, the issue is they only cover a very few filetypes, presumably because the authors didn't want to spend gazillions of hours typing all the data in. This one might be a good base if you wanted to fork or contribute to it: https://github.com/neilharvey/FileSignatures/

https://github.com/neilharvey/FileSignatures is such a package that you can use to detect the actual file type and you can extend it to detect custom signature.

For audio handling, since working with .NET there really wasn't a choice, if not using the NAudio library. This is working pretty well so far, with the ASIO support to get low latency (a must have in the audio world) and many useful features to work with audio samples.

This implementation will use the minimum configuration necessary. For Windows, we’ll also leverage the NAudio package for handling audio playback, as it offers a straightforward solution for recording and playing audio files.

Thanks for the suggestion. I have to rewrite most of the audio signal processing code anyway as I am using NAudio currently. Have heard of PiSound before, and will definitely check it out as it is pretty popular. I just need a way to output an array of numbers, representing the processed sound wave, to turn into an analog signal. Writing this from scratch is unnecessarily complicated when these libraries already exist.

Not tried it but there is also NAudio (https://github.com/naudio/NAudio)

I’ve used NAudio for this. You get Windows support for free, and it’s not too difficult to implement for other platforms. I have gists published for Android and iOS that should get you going.

This might help: NAudio, they have a doc file for working with pitch here
