Tonfall is not meant to be a fully implemented audio engine but you may learn a lot about signal processing and sequencing in common. It covers most questions I am receiving by email and is not that far away from the audio engine we use in Audiotool.
- Holding a list of processors and time information
- SignalProcessor for audio generation taking TimeEvents (like notes) into account
- Design Pattern to process polyphonic audio generation (e.g. synthesizer)
- Static Delay as a template for other effects
- Note to frequency mapping
- WavFile Encoder
- Samples of the Casio RZ1 drumcomputer
- AmenBreak sample
- Super Mario playing Sequencer
- Fully launchable Metronome (Hello World of Audio DSP)
- Simple implementation of ToneMatrix

Thanks for releasing this Andre. Do you think it would be possible to use Tonfall to do some simple live DSP audio processing (using microphone/line input)?

@Og2t: You mean doing something as cool as this? http://labs.sonoport.com/discovox/

Any chance of a “get started” tutorial ?

@Og2t: Go for it. I would add it to Tonfall.
@Ricardo: Check out the examples. They should open the door. No time for a step by step tutorial, I am afraid.

Is this engine useful for audio-visualisation, too? Or is it just for generation?

Thank you very much :)

it will be nice if i can get the getting started tutorial :D

Thanks for sharing!
I would love some examples on sample playing too.

This looks really interesting, but I can’t seem to find any way of downloading this form the google code page..
Is it just me, or are there no downloads on the page? Seems a bit un-handy to download all the .as files one by one :)

It is just you ;)
Download a SVN-Client of your choice and checkout the project.
October 28th, 2010 at 10:12 pm
Ok, figured it out – thanks!
SVN-Clients look very smart :)
I would still like just a package to download from the “download” tab in google code – but that’s just me;)

FL909 was great. I hope you can show us a drum machine example with tonfall this time. can’t work out how to implement a sample processor :(

I am trying to compose a 5 minute piece of computer music for my college class and was interested in using Tonfall for the project. I was wondering if there was a guide or tutorial to get me started with learning and practicing with the framework. Thanks for the help.

Would you like to give me one example of how to use your WavEncoder to encode a byte array ? I found your DemoAudioEncoder.as in demo folder but I can not use it to encode my byte array. In this example, you only encode generated amplitudes.
My situation is like this :
- I use Microphone to record voice.
- I save recorded voice to a bytes array.
Now I want to encode that bytes array.
Thank you so much in advance.
