Re: [Haskell-cafe] Open-source projects for beginning Haskell students?

Sorry; make that http://slavepianos.org/rd/ut/hsc3-texts/hsc3-tutorial.html On 3/22/12, Tom Murphy wrote:

If you want to do Haskell audio synthesis, you could also use hsc3 (good start here: http://slavepianos.org/rd/ut/hsc3-texts/). With hsc3 you can start on serious audio synthesis with only a few lines of Haskell. In my opinion it could use a much larger community.

The task is to implement a small audio synthesizer in Haskell.

seriously?!?! i'm not in his class, but i'm game! i learn better when i'm working on something interesting, and i want to make my (currently pretty pathetic) haskell better and i *LOOOVVVVEEEEE* audio! a haskell-based synth (or series of synths) would be really spiffy! what do i have to know / learn / do?

Well, it's up to you, really. You need to learn a bit how audio synthesis works, for instance starting with the following links.

http://www.acoustics.salford.ac.uk/acoustics_info/sound_synthesis/ http://en.wikibooks.org/wiki/Sound_Synthesis_Theory http://en.wikipedia.org/wiki/Category:Sound_synthesis_types

Then, it's best to learn by programming various wave forms yourself and playing around with them. I just finished implementing the necessary Haskell backend for playing raw audio data. You can find it here:

http://hackage.haskell.org/package/tomato-rubato-openal

The testSine function demonstrates how it works.
