At the request of Don Stuart, here is some information about the formats supported by different sound libraries.
Contents
In-memory data formats
In-memory sound formats are fairly diverse.
Reading and writing sound files
| Library | Sound file format |
|---|---|
| HCodecs | (Audible a) => DiffUArray Int a
|
| hsndfile | MArray with Float and Double
|
| HSoundFile | [[Double]]
|
| ALUT | OpenAL.AL.Buffer
|
| WAVE | [[Int32]]
|
Playing sounds
| Library | Sound file format |
|---|---|
| OpenAL | Ptr UInt8, Ptr Int16, 1-N channels
|
| SDL-mixer | ForeignPtr ChunkStruct, ForeignPtr MusicStruct
|
Sound processing libraries
| Library | Sound file format |
|---|---|
| dsp | Array a, [a]
|
| Synthesizer | [a], StorableVector.Lazy a, (StateT s Maybe a, s)
|
| jack | Operates via mapping functionsmainMono :: (CFloat -> IO CFloat) -> IO ()mainStereo :: ((CFloat, CFloat) -> IO (CFloat, CFloat)) -> IO ()
|
MIDI-based
| Library | Sound file format |
|---|---|
| HCodecs | Reads and writes MIDI files |
| midi | Reads and writes MIDI files |
| alsa-midi | Uses midi library |
| Haskore | Uses midi library |
| YampaSynth | Stand-alone program |
Special-purpose APIs only (FFIs, etc.)
| Library | Sound file format |
|---|---|
| hCsound | CsoundPtr
|
| HasSound / Haskore | OrcExp
|
| hsc3 | UGen
|
No public sound-buffer API
| Library | Sound file format |
|---|---|
| hbeat | The relevant source files are missing! |
| hogg | Very low-level API for Ogg internals only |
| libmpd | No sound buffer API |
| sonic-visualizer | No sound buffer API |
| truelevel | Stand-alone program (uses WAVE) |
| wavconvert | Stand-alone program |
