DobutokO.Sound.Keyboard

Maintainer : [e-mail]

A program and a library to create experimental music from a mono audio and a Ukrainian text. Can work with both WAV and FLAC files if your SoX installation supports FLAC.

Working with input and files

qwerty2dvorak :: ByteString -> ByteString

Converts a string of lowercase ASCII letters being typed on the QWERTY keyboard layout into corresponding Dvorak keyboard layout.

dvorak2qwerty :: ByteString -> ByteString

Vice versa to qwerty2dvorak.

input2BL :: IO ByteString

Get contents into lazy ByteString with filtering of all characters that are not a lower case ascii letters.

readFile2BL :: FilePath -> IO ByteString

Usual way the function readFile2BLGen is used. The text in a file being read is treated as a properly typed (entered) one. So there is no keyboard layout conversion at all.

readFile2BLGen :: String -> FilePath -> IO ByteString

Reads a given file into a lazy ByteString with filtering of all characters that are not a lower case ascii letters. It has additional first command line argument to control the way of treating letters: as being typed (entered) properly (null String), or needed to be converted from qwerty to dvorak layout ("q" String), or vice versa (otherwise).

Conversions

readFileDoubles :: FilePath -> IO (Vector Int)

Usual way the function readFileDoublesGen is used. The text in a file being read is treated as a properly typed (entered) one. So there is no keyboard layout conversion at all.

readFileDoublesGen :: String -> FilePath -> IO (Vector Int)

After reading a file into a filtered lazy ByteString (see, readFile2BLGen) converts the resulting ByteString into a Vector of Int. The arguments have the same meaning as for readFile2BLGen.

takeDoubles :: ByteString -> Vector Int

Converts a lazy ByteString into a Vector of Int using hashStr2.

hashStr2 :: Char -> Char -> Int

Hashes two lower case ascii characters. Is used for controlling frequencies and operators.

convH :: String -> (ByteString -> ByteString) -> ByteString -> ByteString

Auxiliary function to define how is a ByteString treated, see readFile2BLGen.
