How can I read and edit mp3 frame header bits

What I want to do is not get the information about the file but I want to read the bits and also be able to locate bits positions within the frame header. The header is 32 bits (4 bytes) of which is what I want to get back or displayed as a message.

I want to read it, edit it. The bit i want to read is H which is in position bit (8).
Here is the frame header sample

I want to return each of these and alsobe able to locate one such as H and return it value and also loop through by position. eg. Lets say I also want to read a bit at position x and or set it with a value.

What I have tried:

The samples I've seen so far online only shown how to read tags not bits or any similar thing to what I'm looking for.

Solution 1

You can use FileStream for that FileStream.ReadByte Method (System.IO)[^]

Hey guys sorry to take so long to reply, I was still trying out this and I still fail. Well let me put it this way. I want to intentionally corrupt the mp3 file so that it wont be recognized as an mp3 or it format will not be recognized. I want this file be unplayable while also I keep note of how I corrupted the file so that I can correct it back later. XOR seemed to work but only if I XOR the whole file and that takes quite a lot of time to XOR and unXOR the file. The file I don't want it to be recognized as an MP3 once corrupted so that not even MP3 repair, converters can be able to convert or correct this file.

Anyone know how to go about doing that programmatically?
