MARF is a general cross-platform framework with a collection of algorithms for audio (voice, speech, and sound) and natural language text analysis and recognition, along with sample applications (identification, NLP, etc.) of its use. MARF can run distributed over the network (CORBA, Java RMI, and Java XML-RPC Web Services) and may act as a library in applications or be used as a source for learning and extension.
FMS is a tool to create all kinds of sounds from scratch. You can play any sound (sine, triangular, vowels, etc.) with any property settings (frequency, volume, balance, sweep, etc.) and modulations thereof. It also features tools to save sounds, play .MUS music, graphically display sounds, and make real noise.
Secret Rabbit Code is a sample rate converter for audio. It is capable of arbitrary and time varying conversions. It can downsample by a factor of 256 and upsample by the same factor. The ratio of input and output sample rates can be a real number. The conversion ratio can also vary with time for speeding up and slowing down effects.
