问题:

I am Using NAudio for getting MP3 file information as well merging 2 or more MP3 files. It works fine on localhost but when I publish the site on AZURE it throws error "NoDriver calling acmFormatSuggest"

I assume that you are trying to use something that is not installed on the machine in Azure - in your case it is ACM MP3 decoder. On a client Windows it can be pre-installed, but i do not think that server Windows can have it. Also i suspect that something like that will not be allowed to run on Azure Web Apps (it looks like you are trying to use that).

So, i would suggest you to use Virtual Machine for that and install needed components here or use something software-based. I have found:

new Mp3FileReader(stream,wave=> new DmoMp3FrameDecompressor(wave))

It looks like it can be used in your case. Could you please try?

As Alex has said, it is because the MP3 codecs (both ACM and DMO) are not present on the server. Your options are to find a way to install them, or to use a fully managed MP3 decoder such as NLayer instead.
