ZXTune is a set of portable cross-platform applications (GUI/CLI) intended to play chiptunes originally created for ZX Spectrum. It features advanced ripping possibilities that let you search for music in big data sets. Supported playback formats include AY, AS0/ASC, FTC, GTR, PSC, PSG, PSM, PT1, PT2, PT3, SQT, ST1, ST3, STC, STP, TXT, TurboSound, VTX, YM, CHI, DMM, DST, PDT, SQD, STR, TF0/TFE, TFC, TFD, and COP. Supported compressed formats include CHARPRES, CC3, CC4, CC4PLUS, DSQ, ESV, GAM, GAMPLUS, HRUM, HRUST1, HRUST2, LZH1, LZH2, LZS, MSP, PACK2, PCD61, PCD62, TLZ, TLZP, TRUSH. Supported archived/container formats include FDI, HOBETA, HRIP, LHA, RAW, SCL, TD0, TRD, ZXZIP, ZIP, RAR, SNA128, and Z80.
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.
Giada is a minimal, hardcore audio tool for DJs and live performers. Just pick your sample, drop it in any channel, and start the show by using this tiny piece of software as a loop machine, drum machine, sequencer, live sampler, or effect (VST) host. Giada aims to be a compact and portable virtual device for production use and live sets.
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).
Bangarang is a semantically empowered media player. Fully integrated with KDE’s Nepomuk semantic storage, Bangarang has access to indexed media information and automatically shares its own media information, rating, tags, and usage statistics with other Nepomuk powered applications. Anything Phonon multimedia system plays, Bangarang plays. Audio settings and video settings are automatically enabled if the Phonon backend supports it. Plasma desktop widgets with MPRIS support can directly control Bangarang. Bangarang keeps you in control of your media experience. It provides quick access to lists of recently played, highest rated, and frequently played items. The Info View provides helpful information when you need it. Media information can be edited easily. It can fetch artist, song, movie, and TV show information from open data providers like Last.fm, themoviedb.org, and theTVDB.com. Bangarang lets you use either tags or files and folders to organize your media in any way you wish.
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.
