LambdaSound.SaveAndLoad

This module exports some functions for simple loading and saving sounds.

However, keep in mind that loaded sounds have a fixed amound of samples and thus cannot be stretched in duration losslessly. Stretching a sound results in sub- or supersampling and will also shift the pitch. Pitch-retaining stretching has not been implemented yet!

Documentation

saveWav :: FilePath -> Hz -> Sound T Pulse -> IO ()

Save a sound as a wav file using default sampleSound.

loadWav :: FilePath -> IO (Sound T Pulse)

Load a wav as a sound, mixing channels with parallel2.

If you want to to use this with embedIO, you should probably use embedIOLazily instead!

saveRaw :: FilePath -> Hz -> Sound T Pulse -> IO ()

Save a sound as floats.

loadRaw :: FilePath -> IO (Sound I Pulse)

Load a sound from floats.

If you want to to use this with embedIO, you should probably use embedIOLazily instead!

saveRawCompressed :: FilePath -> Hz -> Sound T Pulse -> IO ()

Save a sound as gzip-compressed floats.

loadRawCompressed :: FilePath -> IO (Sound I Pulse)

Load a sound from gzip-compressed floats.

If you want to to use this with embedIO, you should probably use embedIOLazily instead!
