FFSampledSP is a free implementation of the javax.sound.sampled.spi interfaces. It is part of the SampledSP collection of javax.sound.sampled libraries. Its main purpose is to decode audio from various formats at high speed using FFmpeg. To do so, it uses the tagtraum FFmpeg package, which offers FFmpeg binaries configured to decode audio while avoiding CODECs with patent problems. In other words, it supports formats like Ogg and FLAC well, while leaving MPEG-4 and MP3 unsupported.
Slim HTML5 Audio jQuery Plugin is a very simple jQuery plugin to embed an audio player. It can insert HTML to play a given audio file using the HTML5 audio tag. It also inserts the embed container tab as fallback when the audio tag is not supported by the Web browser (e.g., IE7 and 8).
Le Biniou works with music, voice, ambient sounds, and whatever acoustic source you chose. When you run Le Biniou, it gives a revolutionary rendering of the sound you are playing. You can entirely manage the sequences and chose your own series of pictures from the default library, your colour scales, and the kind of alteration you want to apply, or you can let Le Biniou's artificial intelligence run on its own. Forget the old visualizations you are familiar with and discover a new multidimensional (spatial and chromatic) way of comprehending music and sounds for artistic, recreational, or didactic purposes.
SpectMorph allows you to analyze samples of musical instruments and to combine them (morphing). It can be used to construct hybrid sounds, e.g. a sound between a trumpet and a flute, or smooth transitions, e.g. a sound that starts as a trumpet and then gradually changes to a flute. Interpolating between two samples of the same instrument (different attack velocity of a piano) could be interesting. The analysis process decomposes samples into a sum of sine waves (corresponding to the partials present in the signal, or the part of the signal perceived as "tone") and additional noise. SpectMorph is thus based on the research on Spectral Modelling Synthesis.
The Kowalski project aims to provide a data driven, lightweight cross platform audio solution. The target audience is developers of games and similar applications where real time audio plays an important role. The Kowalski engine, which is the runtime component, relies only on host-specific external libraries to pass the final output buffers to the audio hardware. All other processing is done in the engine code. Features include positional audio (distance attenuation, cone attenuation, Doppler shift, binaural panning), real time Ogg Vorbis decoding, a powerful mix bus system, and tools to build, validate, and view Kowalski data.
Libsonic is a free C library for speeding up or slowing down speech. However, it's optimized for speed-ups of over 2X, unlike previous algorithms for changing speech rate. Sonic enables clear playback of audio books at 3X speed, and some blind listeners are able to listen at 6X. Libsonic has also been integrated into several text-to-speech engines. It works well on all platforms, even Android phones without FPUs. Pitch control is also supported.
annoyme is a program that plays a sound effect every time you hit a key on your keyboard to give you the feeling you are using a real typewriter. This can be used to impress colleagues with your typing skills or just for sentimental reasons. It supports various sound input methods, as well as multiple output libraries like ALSA or AO. Most importantly, it is also possible to add more sound themes. Currently, only input for XEvIE (on an X Server) is supported.
