Methods toInt16 :: a -> [Int] Source numChannels :: a -> Int Source Instances C Double C Float (C a, C b) => C ((,) a b)

signalToBinary :: C v => [v] -> [Int] Source

signalToBinaryMono :: C a => [a] -> [Int] Source

signalToBinaryStereo :: C a => [(a, a)] -> [Int] Source

writeInt16Stream :: FilePath -> [Int] -> IO () Source

Uses endianess of the machine, like Sox does.

readInt16Stream :: FilePath -> IO [Int] Source

The end of the list is undefined, if the file has odd length. It would be better if it throws an exception.

writeLEInt16Stream :: FilePath -> [Int] -> IO () Source

Write a little endian 16 bit integer stream via String data and writeFile.

readLEInt16Stream :: FilePath -> IO [Int] Source

The end of the list is undefined, if the file has odd length. It would be better if it throws an exception.

int16ToNum :: C a => Int -> a Source

putInt16Stream :: Handle -> [Int] -> IO () Source

numToInt16Packed :: C a => a -> Int16 Source

int16PackedToNum :: C a => Int16 -> a Source

floatToInt16Packed :: Float -> Int16 Source

doubleToInt16Packed :: Double -> Int16 Source
