The Analysis & Recontruction Sound Engine analyzes a sound file into a spectrogram and is able to synthesize this spectrogram, or any other user-created image, back into a sound.

Changes:
Fast frequency domain full logarithmic scale filtering, fast FFT-based envelope detection, faster analysis (about 100x faster), nearest neighbor downsampling for downsizing spectrogram lines (will be changed for the final 0.2 release), a faster FFT-based sine synthesis method, and a revision of the user interface. Noise synthesis was disabled and will be re-implemented for the final 0.2 release.
