At the request of Don Stuart, here is some information about the formats supported by different sound libraries.
Contents |
1 In-memory data formats
In-memory sound formats are fairly diverse.
1.1 Reading and writing sound files
| Library | Sound file format |
|---|---|
| HCodecs | (Audible a) => DiffUArray Int a |
| hsndfile | MArray Float Double |
| HSoundFile | [[Double]] |
| ALUT | OpenAL.AL.Buffer |
| WAVE | [[Int32]] |
1.2 Playing sounds
| Library | Sound file format |
|---|---|
| OpenAL | Ptr UInt8 Ptr Int16 |
| SDL-mixer | ForeignPtr ChunkStruct ForeignPtr MusicStruct |
1.3 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 functions mainMono :: (CFloat -> IO CFloat) -> IO () mainStereo :: ((CFloat, CFloat) -> IO (CFloat, CFloat)) -> IO () |
1.4 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 |
1.5 Special-purpose APIs only (FFIs, etc.)
| Library | Sound file format |
|---|---|
| hCsound | CsoundPtr |
| HasSound / Haskore | OrcExp |
| hsc3 | UGen |
1.6 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 |
