At last, the first beta version of Evolutif is available! It's based on a new source line and target line model which allows you easily connect objects to each other and control the flow of audio data. Support for connecting audio channels individually instead of on a per-object basis has also been implemented. Other highlights include several new classes such as EvoInputDevice which you can use...

Fixed documentation program gamera to allow class declarations of other classes at the beginning of a header file. Now also replaces the '&' character with "&" to avoid some strings being interpreted as special html character codes. Generated documentation for all classes.
Need to fix: Have separate sections at the top of the file for public and protected functions. The...

The first beta version of Evolutif is expected to be complete within the next few days! We have added several new classes to extend the functionality including a new SourceLine and TargetLine model which allows you to connect any channel on a source object to any channel on a target object. We've also fixed several bugs in the alpha version and written several test programs to try out.

Fixed EvoInputDevice so that the constructor takes an additional argument specifying the size of the object's internal buffer. Found that the pops and clicks in audio from an input device were due to the internal buffer being too small. Also tried implementing the reader/writer algorithm to ensure that no reading takes place when the buffer is empty and no writing takes place when the buffer is...

Implemented new EvoInputDevice class and tested it with default input device (mic in on my machine). Fixed volume bug in EvoMixer. Fixed memory deallocation bug in EvoAudioBuffer and nonexistent file bug in EvoWaveAudioFile. George fixed the connect() function in EvoTargetDevice to support connecting any source channel to any target channel.
Also wrote several small test programs and all ran...

Implemented new EvoIoDevice, EvoInputDevice, EvoOutputDevice and EvoFileRenderer classes. These are still pretty sketchy and need quite a bit of work. Did a major overhaul of EvoAudioManager to implement the new design. Still need to add initialize() function to facilitate better error handling. Also found quite a few problems with EvoAudioBuffer::play() that need to be worked out.

Finally implemented new bandlimited interpolation upsampling code for paFloat32 data format. Other data formats probably will not be supported for resampling in the future because it require the EvoFilterKernel class to support other data types and you can convert any format to paFloat32 and back without any loss of information. Still need to boost volume a bit after (or during) resampling...

The html documentation page for EvoVolumeEffect is all screwed up. We need to fix it! And I guess my documentation program needs a tune up too...

Added the new EvoFilterKernel class. Implemented makeWindowedSinc() and convolve() functions. I will be able to write a much better resampling routine within the next couple of days by using these basic DSP operations. The resampling algorithm will simulate an impulse train by interpolating the input buffer with zero samples and then convolving this with a lowpass filter (windowed sinc, probably...
