NuWav is a pure Ruby audio WAVE file parser and writer.
It currently has support for basic WAVE files, Broadcast Wave Format (bext and mext chunks), and the cart chunk. It will parse other chunks, but doesn't necessarily provide specific parsing for them.
It will look for a class based on the chunk name, so if you want to add 'fact' chunk parsing, you need to define a class like this (n.b. 'fact' chunks are already supported, this is an example from the code):
module NuWav
class FactChunk < NuWav::Chunk
attr_accessor :samples_number
def parse
@samples_number = read_dword(0)
end
def to_s
"<chunk type:fact samples_number:#{@samples_number} />"
end
def to_binary
"fact" + write_dword(4) + write_dword(@samples_number)
end
end
end- Fork the project.
- Make your feature addition or bug fix.
- Add tests for it. This is important so I don't break it in a future version unintentionally.
- Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
- Send me a pull request. Bonus points for topic branches.
